Table:
A table in SQL is a set of data which is systematically displayed in rows and columns.
The CREATE TABLE Statement is used to create a new table.
Syntax:
CREATE TABLE tableName (columnName1 datatype, columnName2 datatype, ... columnNameN datatype); |
Example:
CREATE TABLE EMPLOYEE ( EMP_ID INT NOT NULL, NAME VARCHAR (20) NOT NULL, AGE INT NOT NULL, SALARY INT NOT NULL, PRIMARY KEY (EMP_ID) ); |
Output:
Table created. |
Note: We can use DESC command to see the created table.
DESC EMPLOYEE;
