SQL Scripts : Using the SQL Scripts Maximize Efficiency
SQL or Structured Query Language is a powerful and standard database computer language. It is used with all the RDBM’s to retrieve and manage data. There are three categories of commands in SQL. They are DDL(Data Definition Language), DML(Data Manipulation Language) and DCL(Data Control Language). Examples of Software that use SQL are MYSQL, Oracle, Sybase, SQL Server and more. Though SQL is very good at creating, retrieving and manipulating data, by itself, it lacks the basic programming features. PL/SQL is used to include SQL statements in data driven programs.
Today we walk you through the Graphical User Interface known as SQL Scripts, which help to manage script files. The latter contain the different SQL commands as well as PL/SQL blocks. If the script file contains SQL*Plus commands they are ignored at the time of execution. We assume that you are familiar with the different SQL commands and PL/SQL, if not you can take this course on how the essentials of SQL for PL/SQL programming.
