The ODBC specification supports invoking a stored procedure through a canonical method. If IDS_FEATURE_RPC_SUPPORT is set to Y, the stored procedure is executed as an RPC. If there is a batch of multiple canonical stored procedure invocations and IDS_FEATURE_RPC_SUPPORT is set to B, the batch is executed as a single batched RPC. In all other cases, the procedure is executed as a language event. The IDS_AUX_RPC_TEXT string is used as the verb for the language event. The IDS_AUX_RPC_SEP is a 3-character string which is used to map the ODBC parameter separators "(,)".
