  • CURSOR MANAGEMENT in PL/SQL a Cursor Is a Private SQL Work Area That Oracle Uses to Execute SQL Statements and Store Information
    CURSOR MANAGEMENT in PL/SQL A Cursor is a private SQL work area that Oracle uses to execute SQL statements and store information. Whenever you issue a SQL statement, the Oracle server opens an area of memory in which the command is parsed and executed. This area is called a ​ Cursor . This temporary work area is used to store the data retrieved from the ​ database, and manipulate this data. A cursor can hold more than one row, but can process one row at a time. The set of rows the cursor holds is called the Active Set. ​ ​ TYPES OF CURSOR There are two types of Cursors in PL/SQL:­ (1) Implicit Cursor (2) Explicit Cursor IMPLICIT CURSOR :­ It is declared by PL/SQL implicitly when DML statements like ​ INSERT, UPDATE and DELETE statements are executed. They are also declared when a SELECT statement that returns just one row is executed. When the executable part of a PL/SQL block issues a SQL statement, PL/SQL creates an implicit cursor, which PL/SQL manages automatically. IMPLICIT CURSOR ATTRIBUTES :­ Oracle provides few attributes for implicit cursor ​ called as implicit cursor attributes to check the status of DML operations. These attributes are :­ (1) %FOUND (2) %NOTFOUND (3) %ROWCOUNT (4) %ISOPEN The status of the cursor for each of these attributes is defined in the below table :­ Attribute Return Value Example %FOUND The return value is TRUE, SQL%FOUND if the DML statements like INSERT, DELETE and UPDATE affect at least one row and if SELECT...INTO statement return at least one row. The return value is FALSE, if the DML statements like INSERT, DELETE and UPDATE do not affect any row and if SELECT ….

  • T-SQL: a Simple Example Using a Cursor
    Steve Stedman Freelance SQL Server Consultant http://stevestedman.com T-SQL: A Simple Example Using a Cursor For more information on cursors, also take a look at the free SQL query training provided by Steve Stedman. In SQL Server the cursor is a tool that is used to iterate over a result set, or to loop through each row of a result set one row at a time. It may not be the best way to work with a set of data, but if you need to loop row by agonizing row (RBAR) in a T-SQL script then a cursor is one way of doing it. Note: If you are new to SQL Server and come from an Oracle background, you should know that cursors on SQL Server are different from those on Oracle. Before creating the cursor, we will just start with a simple query that will end up being used in the cursor. Which looks something like this: 1 / 6 Steve Stedman Freelance SQL Server Consultant http://stevestedman.com Now to convert it to a cursor, instead of just a select statement. Step 1: Declare variables to hold the output from the cursor. Step 2: Declare the cursor object; Step 3: Assign the query to the cursor. Step 4: Open the cursor. Step 5: Fetch the first row. 2 / 6 Steve Stedman Freelance SQL Server Consultant http://stevestedman.com Step 5: Loop until there are no more results. In the loop print out the ID and the name from the result set and fetch the net row.
