Hello pgsql-sql, I am the new member for the postgres mailing list. Actually I have been working with mysql, php and perl for a very long time now, and offlate shifted to pgsql. I have many technical difficulties 1. I need to port mysql data to pgsql. I tried both mysql2pg.pl and my2pg.sql. Both have some problem. I think it is got something to do with the auto increment feature that i used in mysql. Can that issue be addressed while porting. 2. Some of the joins that were successfully working in mysql are not working, most importantly LEFT JOIN. eg. SELECT SUM(ACT_DueTab.CableAmount) as NetworkTotal FROM ACT_NetworkTab,ACT_DueTab, ACT_InvoiceTab LEFT JOIN ACT_CustomerTab ON (ACT_CustomerTab.CustCode=ACT_InvoiceTab.CustCode) WHERE ACT_DueTab.InvCode=ACT_InvoiceTab.InvNumber and ACT_NetworkTab.NetCode=3 and ACT_CustomerTab.NetCode=ACT_NetworkTab.NetCode and (ACT_InvoiceTab.InvGenDate <= '2001-08-31' and ACT_InvoiceTab.InvGenDate >= '2001-08-01') ORDER BY ACT_InvoiceTab.InvGenDate DESC This query works fine in mysql, but suffers in pgsql. 3. I was using PEAR for data abstraction layer ( to make code independent of the database), I find that PEAR which worked fine with mysql doesn't work so well with pgsql Any help on all these issues will be greatly appreciated. I am in the midst of a porject porting exercise. -- Best regards, Gurudutt mailto:guru@xxxxxxxxxxxxx Life is not fair - get used to it. Bill Gates
