SELECT * FROM Students WHERE Name LIKE 'M%' We can use any one of the following 3 SQL Server functions, to achieve exactly the same thing. CHARINDEX LEFT SUBSTRING The following 3 queries retrieve all student rows whose Name starts with letter 'M'. Notice none of the queries are using the LIKE operator. SELECT * FROM Students WHERE CHARINDEX('M',Name) = 1 SELECT * FROM Students WHERE LEFT(Name, 1) = 'M' SELECT * FROM Students WHERE SUBSTRING(Name, 1, 1) = 'M'

04 MySQL Tutorial for Beginners: USE, SELECT, result set, DISTINCT, ALL
 
12:35
In this video you will begin to code your first "SQL statements" in MySQL Workbench. The very first thing you need to do is to choose and select a database. The "USE statement" is the one you’re going to need for this purpose, and it's the very first statement you're going to learn. The second statement you're going to learn is the "SELECT statement" which is used to retrieve data from a base table. You code the SELECT keyword followed by a list of column names separated by commas and the FROM keyword followed by the name of the base table from which the query retrieves the data. A "result set" is a table of data resulted from a statement: you can think of it as a temporary table that's created within a database. Note that when you execute a USE statement alone, you do not get any results back, because a USE statement itself does not expect to have any results back. In the SELECT clause, you can code an asterisk as a shorthand to indicate that all of the rows and columns should be retrieved. By default, all of the rows in the base table are included in the result set. In some cases, that means that the result set will contain duplicate rows, or rows whose column values are identical. If that's not what you want, you can include the DISTINCT keyword in the SELECT clause to eliminate the duplicate rows. The DISTINCT keyword prevents duplicate rows from being included in the result set. The ALL keyword causes all rows matching the search condition to be included in the result set, regardless of whether rows are duplicated. The ALL keyword is the default and can therefore be omitted.

SQL injection - Getting the table name  ,  column name  and database name from the database
 
12:25
in this video I will tell you how can get the table name and column and database name from the unknown database. As database connection is written in the server language so we need to run some code before we get to that stage of getting the table name, column name and database from the website To run our sql injection we are going to use, UNION query Step – 1 – In the step one we will try to get the number of column, to do that I will type the user which exist in the database Step – 2 – After knowing the number of column, we will try to get the table name and column name from the database, to do that I will use union query, and I will give below value in the form. Step – 3 – After knowing the table name and database name, we will try to get the table name, in the userprivateinfo table, to do that again I will use union query, and I will give below value in the form. Step – 3 – After knowing the table name and database name and column name, we will run one example to do that again I will use union query, and I will give below value in the form. Note – Although I keep on using Tom, as starting value, for every step, but you can use any value, as it does not matter, weather that value exist in the database or not.

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

A Story of Indexes and Full Table Scans: Finding All the Red Sweets Part 1
 
08:43
"Why isn't Oracle using my index?!" is a common question people have when tuning SQL queries. In this episode Chris compares two methods for finding all the red candies from party bags he's prepared. He shows how these are like a full table scan and an index range scan. He goes on to compare the performance of these two approaches. He shows when a full table scan becomes more efficient than an index range scan and vice versa. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

SQL:Column name starting with digit
 
04:57
In this tutorial, you'll learn how to use column name starting with digit or underscore. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Correlated subquery in sql   Part 60
 
07:59
In this video we will discuss about Corelated Subqueries In Part 59, we discussed about 2 examples that uses subqueries. Please watch Part 59, before proceeding with this video. We will be using the same tables and queries from Part 59. In the example below, sub query is executed first and only once. The sub query resutls are then used by the outer query. In a non-corelated subquery, the subquery can be executed independently of the outer query. Select [Id], [Name], [Description] from tblProducts where Id not in (Select Distinct ProductId from tblProductSales) If the subquery depends on the outer query for its values, then that sub query is called as a correlated subquery. In the where clause of the subquery below, "ProductId" column get it's value from tblProducts table that is present in the outer query. So, here the subquery is dependent on the outer query for it's value, hence this subquery is a correlated subquery. Correlated subqueries get executed, once for every row that is selected by the outer query. corelated subquery, cannot be executed independently of the outer query. Select [Name], (Select SUM(QuantitySold) from tblProductSales where ProductId = tblProducts.Id) as TotalQuantity from tblProducts order by Name Text version of the video http://csharp-video-tutorials.blogspot.com/2013/01/correlated-subquery-in-sql-part-60.html Slides http://csharp-video-tutorials.blogspot.com/2013/09/part-60-co-related-subqueries.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/05/part-1-how-to-find-nth-highest-salary_17.html This is a very common SQL Server Interview Question. There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

Well come to sql server tutorial part 3.1. Today I will show you how to create and modify table in query editor, Using create table and alter table statement. In part 3, I have talked about table, how to create it graphically and data types. In previous tutorial we have created customer table. Now I am going to create same table using query editor. USE TEST_DB CREATE TABLE Customer1 ( [CustomerID] [int] NOT NULL, [FirstName] [varchar](50) NULL, [LastName] [nchar](10) NULL, [BirthDate] [date] NULL, ) First login to sql server management studio. Click new query. Type use database name. Under that database the table will be created. For this tutorial test db is our database name. Now type create table and table name customer table. Press enter then type opening and closing first bracket. In between these bracket type column name data type and constraint. Every column must be separated by a comma sign. Click execute. Refresh database to view the newly created table. In practical environment you may need to modify table. In sql, it is called alter table. Now I will show you how to add and delete column from an existing table. Type alter table and customer table as table name. Then type add, column name and data type. Click execute. Select table. Click refresh. Expand to view newly added column. Now I will show you how to delete a column from a table. Type drop column and column name. Then click execute. COLUMN NAME joining date has been deleted. That’s all for today. Please subscribe to my channel. Don’t forget to comment and like or dislike.

Read from (SELECT) Database table - SQLite3 with Python 3 part 3
 
11:20
In the previous tutorials, we've covered creating a database and populating one, now we need to learn how to read from the database. Reading from a database is where the power of using something like SQLite over a flat file starts to make sense. While we can query the entire table, we can instead just query a single column, or even based on specific row values. Let's see what I mean sample code and text tutorial: https://pythonprogramming.net/sqlite-part-3-reading-database-python/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

Best Way to Write Basic SQL Queries
 
13:33
SQL Server Query writing strategies is something I have yet to find in any book. When enthusiastic SQL students do this, they experience a revelation. The number of errors drops significantly and the speed at writing complex queries increases immediately. Knowing how to narrow down what we are looking for amongst a vast list of choices helps immensely. Grabbing the right tables first and then the fields second is akin to grabbing the right menu before ordering an item from it. In fact, one student named Tim took this back to his team of SQL developers and they immediately implemented this process. We are all used to following steps. Most of the time, actions are sequential from top to bottom or left to right. Other times we complete things in phases. The two phases we are going to use in this exercise apply to joining tables. This is easy to implement as we only need remember to organize first and clean up second. When visiting a new restaurant, we will ask to see the menu, because we want to see all they have to offer. The odds are that we might be interested in half of the items, but only need a few dishes for our group at the table. Looking at the menu is like starting a query with a ‘SELECT *’ statement. Once we have looked at all the fields, we narrow our choice(s) to only the items we want at the time. Sometimes restaurants have multiple menus. My favorite restaurant has a kids’ menu, an adult menu, a gluten-free menu and a drink menu. These menus were each gathered at our table. Ultimately, in my head, a selection was narrowed to what was needed. Phase I: Organize. When building a new query from many tables, we often find ourselves wondering, “Where do I start?” First, lay the steps out by identifying which tables contain the essential data. Second, get all the table joins working with a basic ‘SELECT *’ statement. Third, add any basic filtering criteria. Phase II: Itemize. Once all joins and criteria, such as SELECT, FROM and WHERE are working, we are ready for Phase II. This entails going back and changing our ‘SELECT *’ to an itemized SELECT field list as the final step. Let’s explore how this two-phase process of Organize and then Itemize can be a big time-saver. We are going to use one of the challenges from the last lab. In Lab 3.2 (Outer Joins), Skill Check 2, we needed to get four fields from two different tables. If we were to list all four desired fields and test one table at time, we will get an error as seen on the right side of the figure below. In the figure below we write a SELECT statement and part of the FROM clause. When completed, the FROM clause will have two tables, but for now we just want to get the Location table working. By using the ‘SELECT *’ strategy, we remove any possible errors from line 1. From there, we can focus on the more complicated logic used for joining tables together. We can add tables one at a time until everything is working. This is the Organize phase. NOTE: SELECT * never results in an Error message stating “invalid column name”, however; a SELECT list with itemized field(s) can have this error. After our query is organized and working, we can go back and itemize the SELECT field list to display only the fields that are necessary. This is done during Phase II (Itemize). The steps for this system are broken down as follows: Since SELECT is always the first statement in a query, it’s natural to want to write the field names before writing the FROM clause. However; we can save time and trouble by using the ‘*’ until the entire query is working properly. When this is complete, it is very easy to itemize the field list, with the confidence of knowing it will not cause any problems. Exercise: Simple membership for a club: Table1 (id_Member,name_Member, email_member, title, age, company) Table2 (id_Club,club_name, club_Location, address) Table3 (id_club, id_member,membership_date) Q1: Show all member names, email, age, and company from Table1 Q2: Show all club name, location, and address data Q3: Show member name, club name, club location (hint: Use joins and all 3 tables) You can find all other classes related to this video here: http://www.joes2pros.com/joes2pros/Course/Introduction_To_Microsoft_SQL_Server Enroll Today & Get the First Month for only $1!
