Hi, I'm new with pgSQL and I'm not sure why, but I
keep getting the same error. I want to call a function
that returns a cursor and I keep getting the following
exception:
org.postgresql.util.PSQLException: ERROR: cursor
"<unnamed portal 1>" does not exist
I would appreciate any help with this problem.
This is my JDBC code:
Connection objlConnection =
ConnectionPool.getConnection(saJNDI);
CallableStatement statement = null;
ResultSet rs = null;
try{
statement = objlConnection.prepareCall("{? = call
ret_user(?)}");
statement.registerOutParameter(1, Types.OTHER);
statement.setObject(2, "munoze");
statement.execute();
rs = (ResultSet)statement.getObject(1);
while(rs.next()){
System.out.println(rs.getString(1));
System.out.println(rs.getString(2));
System.out.println(rs.getString(3));
}
rs.close();
statement.close();
} catch (SQLExcepton e){
...
This is my function code:
CREATE OR REPLACE FUNCTION
traer_usuario(pnombreusuario "varchar")
RETURNS refcursor AS
$BODY$
DECLARE
ccursor refcursor;
BEGIN
open ccursor for
select nombreusuario,
contrasena,
idrol
from usuario
where nombreusuario = quote_literal($1);
RETURN ccursor;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
