Passing rowset

Question

A developer at our site says that we should pass a javax.sql.rowset into a stored procedures from a java class using JDBC. Is this possible and where can I find a sample?

Answer 1

Rowsets read cursors DO come from the database, however, Rowsets read data-to-pass-in-to-stored-proc need to be created in Java.
We had this issue as well, where we had a stored-proc that needed to take in one parameter, but that parameter would be a list (collection, cursor, array, table, etc.) of search tokens with which to perform a search.
As far as I know you can't pass a javax.sql.rowset into a stored prcedure from java, however what you can do is use Index-By tables.
Using an oracle.jdbc.OracleCallableStatement, you can bind an Index-By table from a java array, something like this:
OracleCallableStatement ocstmt = (OracleCallableStatement) conn.prepareCall("begin pkg.stored_procedure(?); end;");
int[] data = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }
ocstmt.setPlsqlIndexTable(1, data.length, data.length, OracleTypes.NUMBER, 0);
ocstmt.execute();
conn.commit();
ocstmt.close();
connt.close();
To use this approach you will need the Oracle JDBC 10g drivers.
Be warned though, I have a standalone java class with a main method which can run this code fine, passing the array into PL/SQL, which then could do whatever it wanted with it. However, I still cannot get this to work in a servlet.
