What is the SQL UPDATE statement?

Rating:

The SQL UPDATE statement allows a user to update the current values in a database with new values. It contains three main clauses. The first clause specifies the table that requires an update, the second clause specifies the column name and the data values that will be inserted in place of the current values, and the third clause specifies the criteria for the records that will be updated. An example query is given below:

Update Employee{first clause}
Set Fname="Roger"{second clause}
Lname="Pressman"
WHERE Empid=1{third clause}
