The IP must implement any function it has registered for handling custom scalar functions. When a scalar function is identified in a query, the OpenAccess SDK SQL engine first tries to find a match from its built-in functions. If it doesn't find a match, then it searches in the list of function registered by the IP as part of the INIT_SCALAR operation. If the OpenAccess SDK SQL engine finds a match in the IP registered list of scalar functions, it calls that function. Otherwise, an error is reported.
Refer to the DataDirect OpenAccess SDK Programmer's Guide for more information on OpenAccess SDK built-in and IP-defined scalar function processing.
