Hi all.
I'm having problems obtaining resultsets from a pgsql function, I've
read the jdbc documentation, and read similar messages in the lists, but
I still cannot make it work. Perhaps someone can see what's wrong with
my code, because I can't find it :(
my plgpsql function is:
CREATE OR REPLACE FUNCTION usuarios_load(INTEGER) RETURNS REFCURSOR AS '
DECLARE
result REFCURSOR;
BEGIN
OPEN result FOR SELECT * FROM usuarios WHERE id=$1;
RAISE NOTICE ''usuarios_load() -> %'', result;
RETURN result;
END;
' LANGUAGE 'plpgsql';
my java code is:
conn.setAutoCommit(false);
cstmt=conn.prepareCall("{ ? = call usuarios_load( ? ) }");
cstmt.registerOutParameter(1, Types.OTHER);
cstmt.setInt(2, 33);
cstmt.execute();
rs=(ResultSet)stmt.getObject(1);
while (rs.next()) {
System.out.println(rs.getString(0)); << throws exception
}
the logs says:
2003-12-15 16:54:35 LOG: statement: set datestyle to 'ISO'; select
version(), case when pg_encoding_to_char(1) = 'SQL_ASCII' then 'UNKNOWN'
else getdatabaseencoding() end;
