postgresql with jdbc and stored procedures (functions): ResultSet

Question

I just tried to call a stored function from the server (getStat), that is looking like this:

create type stat as (type text, location text, number int);
create f         


        

Answer 1

No need to use a CallableStatement with the {call ...} syntax.

Just use a select and a regular Statement:

Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery("select * from getStat()");
while (rs.next())
{
  System.out.println(rs.getString(1));
  System.out.println(rs.getString(2));
  System.out.println(rs.getInt(3));
}
