COUNTSET is an overloaded scalar function. It is defined with the following parameter data types for the following (target_arg [,target_value_arg]) input combinations:
|target_arg type||target_value_arg type (optional)|
The maximum supported size (n) for VARBYTE is 8192 bytes.
All expressions passed to this function must either match these declared data types or can be converted to these types using the implicit data type conversion rules that apply to UDFs.
The UDF implicit type conversion rules are more restrictive than the implicit type conversion rules normally used by Vantage. If any argument cannot be converted to one of the declared data types by following UDF implicit conversion rules, it must be explicitly cast.
If any argument cannot be converted to one of the declared data types, an error is returned indicating that no function exists that matches the DML UDF expression submitted.
