[quote="adminaia"]I speed up Join-Node #1 by filtering my 1st MySql-Node. And my second Join-Node has only 20.000 values to match. But it would be very nice if someone could check how to JOIN 3 tables in ONE SQL-Node. Greetings[/quote]

Brings fast solutions. <br />But today i faced a big problem while JOINING two MYSQL tables with about 370k records in. Each! <br /> <br />I build a first connector to table CONTACT and a second one to table ADRESS. Joining them all took hours (days?). I killed the job meanwhile. <br /> <br />Reducing the amount of values with WHERE lastname = 'smith' in table1 and where country = 'italy' in table2 will produce a fast result. <br /> <br />My second approach was to use the generic ODBC connector for mysql. It is faster to configure but i can not select different values with WHERE. <br /> <br />Any idea how to speed up?</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="templates/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
