SQL: Delete Vs Truncate Vs Drop
In this tutorial, you'll learn the difference between delete/drop and truncate. 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.

How to Implement and Differentiate Delete and Drop Commands in Oracle 10g .
Hello Guys, Today we will see basic difference between Delete and Drop Commands in Oracle 10g Database, Then after we will Conclude the difference between two. Lets see.... Hence we can Conclude that Delete command only deletes specific or all the records of the table, But Delete commands does not delete Structure of the table, While Drop command deletes all the records of the table as well structure of the table. We can see whether table Structure exists or not using Desc command or select query command. Thank you for Watching. Subscribe my Channel for more videos. Thank you.

GridView insert update delete in asp.net - Part 23
Link for csharp, asp.net, ado.net, dotnet basics and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for text version of this video http://csharp-video-tutorials.blogspot.com/2013/03/gridview-insert-update-delete-in-aspnet.html In this video we will discuss about performing an insert, update and delete on asp.net gridview control using sqldatasource. We will be using tblEmployee table for this demo. SQL script to create and populate this table with sample data is available in Part 13 of asp.net gridview tutorial. Create an asp.net web application. Drag and drop a gridview and a sqldatasource control on WebForm1.aspx. Configure "SqlDataSource1" control 1. Right click on "SqlDataSource1" control and select "Show Smart Tag" 2. Now click on "Configure Data Source" link 3. Select connection string, from the dropdownlist on "Choose your data connection" screen. You need to have a connection string specified in web.config file. 4. Click Next 5. On "Configure the Select Statement" screen, select "tblEmployee" table from dropdownlist. 6. Click on "Advanced" button 7. Select "Generate INSERT, UPDATE and DELETE statements" checkbox and click OK 8. Click Next and Finish Drag and drop gridview control on WebForm1.aspx. Now let us associate "SqlDataSource1" control with "GridView1" control 1. Right click on "GridView1" control and select "Show Smart Tag" 2. Select "SqlDataSource1" from "Choose Data Source" dropdownlist 3. Select "Enable Deleting" and "Enable Editing" checkboxes. At this point "Delete" and "Edit" buttons should appear on the gridview control. We will be using gridview control's footer for inserting a new record. Set "ShowFooter" property of the GridView1 control to "true". This can be done from the properties window, or in the HTML. By default GridView control has generated bound fields to display EmployeeId, Name, Gender and City columns. We need to convert these bound fields into template fields. This can be done very easily using the designer. 1. On the "GridView Tasks" pane click on "Edit Columns" link button. 2. Select "EmployeeId" from "Selected Fields" section and click on "Convert this field into a template field" link 3. Do the same for Name, Gender and City Now modify the template fields in the HTML. Please note 1. In every TemplateField, along with EditItemTemplate and ItemTemplate, we also need FooterTemplate. 2. A dropdownlist is used in EditItemTemplate and FooterTemplate of "Gender" template field, instead of a textbox control. 3. To validate data during edit and insert operations, notice that, we are using validation controls, in EditItemTemplate and FooterTemplate. 4. A linkbutton is used in the footer template of "EmployeeId" template field, to enable the user to insert a new employee row 5. We have used ValidationGroup="Insert" for all the validation controls in FooterTemplates. LinkButton's ValidationGroup is aslo set to "Insert", so that all the validation controls in in FooterTemplates are fired only on Insert LinkButton click. 6. We have set LinkButton's OnClick="lbInsert_Click". 7. After the closing tag of GridView, notice that we are using 2 validationsummary controls, to display all the validation messages in one place. ValidationSummary1 control's ValidationGroup is set to "Insert". ValidationSummary1 control displays all insert related validation errors, and edit related validation errors are displayed using ValidationSummary2 control. Finally copy and paste the following event handler method in WebForm1.aspx.cs protected void lbInsert_Click(object sender, EventArgs e) { SqlDataSource1.InsertParameters["Name"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtName")).Text; SqlDataSource1.InsertParameters["Gender"].DefaultValue = ((DropDownList)GridView1.FooterRow.FindControl("ddlGender")).SelectedValue; SqlDataSource1.InsertParameters["City"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtCity")).Text; SqlDataSource1.Insert(); }

Oracle SQL 05 How to Creating a Table SQL Developer
USING SQL COMMAND Types of SQL Commands The following sections discuss the basic categories of commands used in SQL to perform various functions. These functions include building database objects, manipulating objects, populating database tables with data, updating existing data in tables, deleting data, performing database queries, controlling database access, and overall database administration. The main categories are DDL (Data Definition Language) DML (Data Manipulation Language) DQL (Data Query Language) DCL (Data Control Language) Data administration commands Transactional control commands Defining Database Structures Data Definition Language, DDL, is the part of SQL that allows a database user to create and restructure database objects, such as the creation or the deletion of a table. Some of the most fundamental DDL commands discussed during following hours include the following: CREATE TABLE ALTER TABLE DROP TABLE CREATE INDEX ALTER INDEX DROP INDEX CREATE VIEW DROP VIEW Manipulating Data Data Manipulation Language, DML, is the part of SQL used to manipulate data within objects of a relational database. There are three basic DML commands: INSERT UPDATE DELETE Selecting Data Though comprised of only one command, Data Query Language (DQL) is the most concentrated focus of SQL for modern relational database users. The base command is as follows: SELECT This command, accompanied by many options and clauses, is used to compose queries against a relational database. Queries, from simple to complex, from vague to specific, can be easily created. The SELECT command is discussed in exhilarating detail during Hours 7 through 16. A query is an inquiry to the database for information. A query is usually issued to the database through an application interface or via a command line prompt. Data Control Language Data control commands in SQL allow you to control access to data within the database. These DCL commands are normally used to create objects related to user access and also control the distribution of privileges among users. Some data control commands are as follows: ALTER PASSWORD GRANT REVOKE CREATE SYNONYM You will find that these commands are often grouped with other commands and may appear in a number of different lessons throughout this book. Data Administration Commands Data administration commands allow the user to perform audits and perform analyses on operations within the database. They can also be used to help analyze system performance. Two general data administration commands are as follows: START AUDIT STOP AUDIT Do not get data administration confused with database administration. Database administration is the overall administration of a database, which envelops the use of all levels of commands. Database administration is much more specific to each SQL implementation than are those core commands of the SQL language. Transactional Control Commands In addition to the previously introduced categories of commands, there are commands that allow the user to manage database transactions. COMMIT Saves database transactions ROLLBACK Undoes database transactions SAVEPOINT Creates points within groups of transactions in which to ROLLBACK SET TRANSACTION Places a name on a transaction Transactional commands are discussed extensively during Hour 6, "Managing Database Transactions." sql interview questions,sql interview questions and answers,interview questions for freshers,SQL,sql tutorial BEGINNERS,oracle,pl sql,pl/sql,mysql,oracle interview,google interview question,trigger in oracle,dbms,rdbms, oracle tutorial,pl sql basics,pl sql tutorials, pl sql example,sql,sql server ,query,sql query,questions,interview questions,coding interview,sql coding, code , database interview questions and answers,interview questions sql, interview questions,sql server,sql interview,interview sql,interview question sql join ,inner join, group by,select sql,interview questions ,sql basic, PL SQL Programs,PL SQL,PL SQL block,PL SQL Function,PL SQL Package,PL SQL Package body,PL SQL Procedure ,PL SQL Trigger,PL SQLType,PL SQL Type body,CREATE OR REPLACE PROCEDURE,database interview questions and answers,interview questions sql, interview questions,sql server,Procedural Language,interview sql,interview question sql join ,inner join, group by,select sql,interview questions ,sql basic,pl sql variable,oraclecoach,claire rajan, PL SQL,PL SQL block,PL SQL Function,PL SQL Package,PL SQL Package body,PL SQL Procedure,PL SQL Trigger,PL SQLType,PL SQL

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.

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
