Oracle PL/SQL Insert, Update, Delete & Select Into
PL/SQL is a procedural language extension to SQL. It supports all the features of SQL, including complex queries, data manipulation, and transaction control. In addition, PL/SQL offers many features that are not available in SQL, such as conditional compilation, loops, dynamic SQL, and exception handling.The most basic PL/SQL block consists of a series of statements enclosed in the keywords DECLARE, BEGIN, and END. For example:DECLAREv_employee_id NUMBER(6)v_last_name VARCHAR2(20);v_salary NUMBER(8,2);BEGINSELECT employee_id, last_name INTO v_employee_id, v_last_name -- line 1FROM employees -- line 2 -- table or view name must follow the FROM keyword on line 2!WHERE employee_id = 100;PL/SQL is a procedural language extension to SQL that adds control structures, looping, and other features to the standard SQL command set. In this tutorial, you will learn how to use the PL/SQL INSERT, UPDATE, and DELETE statements to manage data in Oracle tables. You will also learn how to use the PL/SQL SELECT INTO statement to query data from Oracle tables.PL/SQL is a procedural language extension to SQL. It has procedural programming, conditions and loops. It is used in Oracle database to write stored procedures,triggers and functions.INSERT : Used to insert new rows into a table.UPDATE : Used to modify existing rows in a tableDELETE : Used to delete existing rows from a table.SELECT INTO : Used to retrieve data from a table into variables or records.PL/SQL is Oracle's procedural extension to industry-standard SQL.
