Table:

In SQL, a table is a set of data that is displayed systematically in rows and columns.

To create a new table, use the CREATE TABLE statement.

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 the DESC command to see the created table.

DESC EMPLOYEE;
