ADMIN_IsInteger

Deprecated.

This function can be used to check if a given string is formally an integer, i.e. if the string contains only digits with an optional leading plus och minus character.

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

This function should NOT be used when determining whether a conversion to int or bigint is possible since it does not perform any overflow check. In these cases you should use the functions ADMIN_IsInt or ADMIN_IsBigint instead.

Type: Scalar function
Area of use: General use

Return value: bit

Returns 1 if the string is formally an integer and 0 otherwise.

Parameters:

@str mandatory varchar(8000)
