hello everybody,
I have created a function to display the rows in a table. The function is
returning the refcursor. I am calling the refcursor in Callable Statement, but
i am getting No class found for refcursor. I have seen these queries earlier in
this forum.
I am using postgresql 7.3.4 and pg74.215.jdbc3.jar.
As per the solutions given for earlier queries i tried to give getString(1), but
i am getting null value.
i am attaching the code along with this mail.
This is my pl/pgsql
CREATE or REPLACE FUNCTION displayall() RETURNS refcursor AS '
DECLARE
cursor1 cursor for select pageid,keyword from Maintable;
BEGIN
open cursor1;
return cursor1;
END;
'language 'plpgsql';
My jdbc code is
con.setAutoCommit(false);
CallableStatement cstmt2=null;
cstmt2=con.prepareCall("{? = call displayall()}");
cstmt2.registerOutParameter(1,Types.OTHER);
cstmt2.executeUpdate();
ResultSet rs2=(ResultSet)cstmt2.getObject(1);
i am getting No class found for refcursor and the error is pointing to
cstmt2.executeUpdate() line.
I also tried to use
con.setAutoCommit(false);
CallableStatement cstmt2=null;
cstmt2=con.prepareCall("{? = call displayall()}");
cstmt2.registerOutParameter(1,Types.OTHER);
String test=cstmt2.getString(1);
But test is pointing to null.
Can anyone please help me in solving this problem. I need to sort out this issue
at the earliest as i need to use Callable Statement in JDBC and also pl/pgsql.
Reply awaited.
Regards
P.mani
