The Syntax of the Transact SQL Update Statement

The SQL Server Transact SQL Update statement can be used to update an existing row or rows of adatabase table. The update statement's syntax is as follows:

UPDATE <table name>
SET <columnname1> = <columnvalue1>, <columnname2> = <columnvalue2>
WHERE <column> = <value>

The WHERE clause in the Update SQL statement is optional. If a WHERE clause is not specified then all of the rows in that table will be updated.

A SQL code syntax example of using the Update statement is shown below:

UPDATE t_Products
SET ProductName = 'Microsoft SQL Server' ProductPrice = '$995'
WHERE ProductID = 112

Table rows can be inserted into a table by using the Insert Into statement. Here's the syntax of the SQL Insert Into query. A table can be created using the SQL Create Table function.
