Passing SQL string to Stored Procedure

Question

I have the following package:
CREATE OR REPLACE PACKAGE PKG_QUERY
AS
TYPE CURSOR_TYPE IS REF CURSOR;
PROCEDURE SP_QUERY(QUERY IN OUT CURSOR_TYPE);
END;
CREATE OR REPLACE PACKAGE BODY PKG_QUERY
AS
PROCEDURE SP_QUERY(QUERY IN OUT CURSOR_TYPE, IN_SQL IN VARCHAR2)
AS
BEGIN
OPEN QUERY FOR IN_SQL;
END;
END;
Here is what I would like to do. I would like to pass an SQL string that I build in my middle tier and pass it to the SP_QUERY procedure as IN_SQL. I can't seem to get this to compile. If I explicitly type in a select statement (ex. OPEN QUERY FOR SELECT * FROM table), it works fine. Can I pass in an SQL statement as a string and execute the query? Any help that anyone can offer would be GREATLY appreciated!!!!
Thanks for any help you can offer,
Michael

Answer 1

String bigString = getBigString(); // wherever it comes from
ByteArrayInputStream bais =
         new ByteArrayInputStream(bigString.getBytes());
PreparedStatement ps = conn.prepareStatement("INSERT INTO SOMETABLE VALUES(?)"); 
//above is just an example, use your insert statement
ps.setAsciiStream(1,bais,bigString.length());Of course, that is assuming you have some type of CLOB in your database.
