This function can be used to validate if a conversion to the numeric (or decimal) 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(numeric(x, y), z);

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

Type: Scalar function
Area of use: General use
