UPDATE Command
The UPDATE operation is a part of DML (Data Manipulation Language) in SQL Server which is used for updating the existing data in the table of the database. It is one of the basic operations that gets used frequently when there needs a change in the data of the table. We can update single as well as multiple columns based on the condition we want by using the WHERE clause. The data modifications are very easy using UPDATE Commands.
Syntax:
UPDATE table_name SET column_name1 = value1 , column_name2 = value2,..
WHERE condition
Parameters: column_name1 and column_name2 are the columns for which new values need to be assigned, the condition is the condition on which to apply the update.
Explanation: We use the SET Operator to set new values that we want to place in place of old values. Generally, we use the WHERE clause to update existing values because there are lots of records present in the table, if we want to update a particular record then we use the WHERE Clause over theirs to update the record.
