Introduction of Update in SQL Server

In SQL Server, the UPDATE statement is used to modify existing records in a table. It allows us to change the values of one or more columns in a specified set of rows based on a specified condition.

Syntax:

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

Explanation:

• table_name: The name of the table we want to update.
• column1, column2, ...: The columns we want to update.
• value1, value2, ...: The new values we want to assign to the specified columns.
• WHERE condition: The condition that specifies which rows to update. If satisfied then all rows in the table will be updated.

SQL Server is a Relational database Management system which is developed by Microsoft and is one of the most used databases in the world. It provides the developer with a set of rich functionalities to create tables, insert data in them, and then manipulate and play with them as and when necessary.
