# *= (Multiplication Assignment) (Transact-SQL)
[!INCLUDE [sql-asdb-asdbmi-asa-pdw](../../includes/applies-to-version/sql-asdb-asdbmi-asa-pdw.md)]

Multiplies two numbers and sets a value to the result of the operation. For example, if a variable @x equals 35, then @x *= 2 takes the original value of @x, multiplies by 2 and sets @x to that new value (70).
