You can use the system tableDBPROCPARAMS to determine the following database information, among other things:
· All input parameters of the database function AVGPRICE in the HOTEL schema and the following parameter information: data type, length and the number of the affected parameter in the range of all parameters within that database function.
SELECT parametername, datatype, len, dec, pos
FROM DOMAIN.DBPROCPARAMS
WHERE schemaname = 'HOTEL'
AND dbprocname = 'AVGPRICE'
AND "IN/OUT-TYPE" = 'IN'
· All output parameters of the database procedure AVG_PRICE in the HOTEL schema and the following parameter information: data type, length and the number of the affected parameter in the range of all parameters within that database procedure.
SELECT parametername, datatype, len, dec, pos
FROM DOMAIN.DBPROCPARAMS
