HELP: collection as in parameter of SP using jdbc

Question

Hi, everyone:
i'm trying to pass an array of int value to a stored_procedure using jdbc, but i cannot figure out how to write the exact code.
i always get the same exception: java.sql.SQLException: invalid name schema.
i have searched this section and found some examle(Call a procedure/function with an array as argument i tried that example code, but it cannot work too, the same exception.
here is my jdbc code:
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:test";
Connection conn = null;
Class.forName(driver);
conn = DriverManager.getConnection(strUrl, "zzuliTV", "123456");
CallableStatement proc = null;
proc = conn.prepareCall("{ call TEST_TABLE_INT_PARAM(?,?) }");
int elements[] = { 1, 2, 3, 4 };
ArrayDescriptor desc = ArrayDescriptor.createDescriptor("TEST_PACKAGE.ID_TABLE", conn);
//ARRAY aArray = new ARRAY(desc, conn, elements);
//proc.setInt(1,-1);
//proc.setArray(2, aArray);
//proc.execute();
proc.close();
conn.close();
pl/sql code:
create or replace
PACKAGE TEST_PACKAGE AS
type ID_TABLE is table of number(10,0);
END TEST_PACKAGE;
in the jdbc code, the statement "ArrayDescriptor desc = ArrayDescriptor.createDescriptor("TEST_PACKAGE.ID_TABLE", conn);" caused the exception.
i have tried the code "ArrayDescriptor.createDescriptor("ID_TABLE", conn);" or written the pl/sql nested table globally or written an varray instead, but all failed, always the same exception.
i use oracle 11g.
Could anyone help me, thanks a lot.

Answer 1

The error might be caused by your collection being defined inside of "TEST_PACKAGE", which I presume is a PL/SQL package.
JDBC does not support Object nor Collection types defined inside packages.
So, your attempt to globally define your "ID_TABLE" is the correct way to go.
create type id_table as table of integer;
or
create type id_table as varray(#) of integer;
Both are valid global definitions. I think that you said that you tried this unsuccessfully.
You may want to try rewriting your elements declaration as follows.
int elements\[] = new int\[]{1, 2, 3, 4};
However, your declaration is probably fine. Another suggestion is to use CallableState.setObject() instead of setInt() and setArray().
proc.setObject(1, new Integer(-1));
proc.setObject(2, aArray);
Also note that for 11g, the driver class is "oracle.jdbc.OracleDriver"
Only other thing I can think of is to make sure the collection is defined in your schema or, if another, you have permission to it.
That's all I can think of. Here is a link that describes using collections with JDBC. You may find it useful.
