Program Plan Intro
SQL:
- SQL stands for “Structured Query Language”.
- The current version of SQL is “ANSI SQL – 92”.
- SQL is not a
programming language. It is text-based and it is also called as data sublanguage.- In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.
- It contains constructs which are used to define and process
database . They are executed using DBMS-supplied command prompt. - Some of the DBMS products provide GUI tools in order to perform tasks are as follows:
- SQL Server
- Oracle Database
- MySQL

Creating table comes under Data Definition Language (DDL). Syntax for creating table is as follows:
CREATE TABLE TABLE_NAME (
Column1 datatype,
Column2 datatype,
…
);
