I just converted a working app from MySQL to PostgreSQL. I used fabForce's DBDesigner 4 to build and maintain my data model in MySQL. To port the schema, I exported the data model to an SQL file, and hand tweaked the file to change datatypes and move INDEX statements out of the Create Table statements. Everything worked like a charm. I can switch back and forth between the two databases by simply changing the ODBC connect string. Here's my problem, though: queries in mySQL are almost instantaneous, whereas those same queries in PostgreSQL can take four seconds or more - even when I'm hitting a table with only one row. I'll bet I have something misconfigured, but I'm a newbie FNG, and I don't yet know my way around yet. BTW, I did a search on mySQL in the novice threads, and performance seems like a hot-button issue. Please be assured that I have no issues or agendas with either product, and fully assume that I have something misconfigured. I'm slightly overwhelmed by the volume of documentation (on-line, and I bought books by Douglas&Douglas and Matthew&Stone) and would like a few points in the correct direction. Help is absolutely appreciated. Regards, Jim Brown PostgreSQL 8.1.3 PostgreSQL ANSI ODBC driver 8.01.02.00 PSQLODBCA.DLL 1/31/2006 __________________________________________________ Do You Yahoo!?
