Hello Francisco, I find "PEAR DB" particularly a wonderful data abstraction layer. I have been working with for a long time and so far I have had minor difficulties while porting from one database to another. I have worked with PEAR DB on three databases, MySQL with BDB tables, Postgresql and Oracle. It works fine with all the three, but I must confess my working with Oracle based data interface is limited. Just one small aspect to be taken care of while using PEAR DB is that, u need to use quotes to enclose the fields. Speed of operation is very good in terms that, user hardly notices the difference of data abstraction layer being present. -- Best regards, Gurudutt mailto:guru@xxxxxxxxxxxxx Life is not fair - get used to it.
