A Boolean value that specifies whether the CONCAT_NULL_YIELDS_NULL database option is active.
If True, the concatenated result is NULL.
If False (default), the value is concatenated with a zero string.

Remarks

This property specifies whether a value that is concatenated with a null value results in a null value or in a zero string.

This option can also be changed by using the Transact-SQL ALTER DATABASE statement.
