- In order for Crystal Reports to report of an Oracle stored procedure, all of the following requirements must be satisfied:
- When using an ODBC connection to access an Oracle stored procedure, you must create a package that defines the REF CURSOR. This REF CURSOR must be strongly bound to a static pre-defined structure. This package must be created separately and before the creation of the stored procedure.
- When using an Oracle native connection, it is possible to report off the Oracle stored procedure that created within a package and also an Oracle stored procedure that references a weakly bound REF CURSOR.
- The stored procedure must have a parameter that is a REF CURSOR type. Crystal Reports uses this parameter to access and define the result set that the stored procedure returns.
- The REF CURSOR parameter must be defined as IN OUT (read/write mode). After the stored procedure has opened and assigned a query to the REF CURSOR, Crystal Reports will perform a FETCH call for every row from the query’s result. This is why the parameter must be defined as IN OUT.
- The parameters can only be defined as IN (input) parameters. Crystal Reports is not designed to work with OUT parameters.
- The REF CURSOR variable must be opened and assigned its query within the procedure.
- The stored procedure can only return one record set. The structure of this record set must not change based on parameters.
- The stored procedure cannot call another stored procedure.
- If you are using the CR Oracle ODBC driver, check the option: "Procedure Returns Results" under the tab "Advanced" in the CR Oracle ODBC DSN
- If you are using the native Oracle driver and using hard-coded date selection within the stored procedure, the date selection must use either a string representation format of YYYY-DD-MM (where the date field = 2004-01-01) or the To_Date formula function with the same format specified (where date field = To_Date(2004-01-01’,’YYYY-MM-DD’).
- Most importantly, the stored procedure must be able to execute successfully in Oracle’s SQL *Plus utility.
- If all of the above requirements have been met, verify the database driver that you are using works with that version of Oracle outside of Crystal Reports.
