Type: Scalar function

This function can be used to validate if a conversion to the uniqueidentifier datatype is possible for a given string.

The special case of a null-string will give a return value of 0.


Use the built-in SQL server function

SELECT TRY_CONVERT(uniqueidentifier, x);

Be careful with differences in behavior for '' and trailing/leading whitespace characters, space, tab new line etc.

Return value: bit

Returns 1 if conversion is possible and 0 otherwise.


@str mandatory varchar(8000)
