SQL UPDATE statement

The UPDATE statement is used to modify the existing record in a table.

Syntax:

UPDATE tableName SET columnName1 = value1, columnName2 = value2,..., columnNameN = valueN 
WHERE [condition]

Use where condition if you want to update a specific record otherwise all records will update.

Example:

UPDATE EMPLOYEE SET EMP_NAME = 'Parmender' WHERE EMP_ID = '5';

Output:

1 row(s) updated.
