Hey all,

I've been tasked with writing Java that accesses Oracle 8i, MSSQL and DB2 seamlessly. To hide much of the RDBMS logic, I've written many stored procedures whose task it is to retrieve rows and return the rows to the Java methods. Here is what works for DB2/MSSQL:

      try {
        CallableStatement stmt = conn.prepareCall("{call
SSSLOG_GETSOURCES}");
        try {
          ResultSet rs = stmt.executeQuery();
          try {
            while (rs.next()) {
              System.out.println(rs.getInt(1) + ", " + rs.getString(2));
            }
          } finally {
            rs.close();
          }
        } finally {
          stmt.close();
        }

      } finally {
        conn.close();
      }



SSSLOG_SOURCES is defined in MSSQL as follows:

CREATE PROC SSSLOG_GETSOURCES
AS
 SELECT *
 FROM SSSLOGSOURCES
 ORDER BY LOGSOURCEDESC
GO

In Oracle, I understand (by trying to read the documentation and looking at various posts), that a Stored Procedure can't return a rowset. But, a function can. And, the way to get it to return the data is somehow through a cursor - like:

CREATE OR REPLACE PACKAGE TYPES
AS

    TYPE CURSORTYPE IS REF CURSOR RETURN SSSLOGSOURCES%ROWTYPE; END;
/

/*


However, when I run through the Java code above, it claims that there is no such procedure or function. If I change the code to call another stored procedure I've written that doesn't return a dataset, it is found. What's going on? Also, when I simply invoke it from SQL Plus, SQL Plus complains it's not there. But if I use this syntax:

variable b refcursor
exec :b := SSSLOG_GETSOURCES
print :b

I can see that it works and it's there.

Why can't the Java App above find it? It can find all the other SPs I've written (although the others it finds are CREATE PROCEDURE... and not CREATE FUNCTION...) TIA Marc Received on Thu Apr 05 2001 - 13:54:11 CEST
