0100,0100,0100Hi there I have a relatively simple problem : I have a field named "id" that has type "Auto-number" in an Access database table. I know there is no 'auto_number' type in PostgreSQL. I know also, that SERIAL and SEQUENCE are workarounds for this problem, but I'm not sure how to make a field a SERIAL once its already created in the table. I have tried making the DEFAULT value of field "id" set to SERIAL, but I get this error : FF00,0000,0000PostgreSQL said: ERROR: Attribute 'serial' not found  Your query:  ALTER TABLE "names" ALTER "id" SET DEFAULT SERIAL 0000,0000,0000This is my system : odbc driver version (on Win machine) : 7.01.00.04 Insight Distrib. (PSQLODBC.DLL) odbc driver version (on Red Hat machine) : postgresql-odbc-7.0.2-17.rpm postgre database version : postgresql-7.0.2.rpm error messages on screen : none. the commlog file : see attached file (psqlodbc.log) 0100,0100,0100Suggestions, workarounds and prayers would be appreciated ! love rich handler
