Your IP must modify IP GETSUPPORT to return support for IP_SUPPORT_TABLE_FUNCTIONS.
You can update the support array if the IP GETSUPPORT function uses the support array, or you can modify the IP GETSUPPORT function to enable the support for table functions.
Updating the support array
IP_SUPPORT_TABLE_FUNCTIONS must be set to 1 in the support array to indicate that the IP supports table functions.
Using the GETSUPPORT function
The IP GETSUPPORT function must return TRUE for IP_SUPPORT_TABLE_FUNCTIONS.
Note: If IP GETSUPPORT does not indicate support for IP_SUPPORT_TABLE_FUNCTIONS, OpenAccess SDK returns an error for a query with table functions.
