I am accessing PostgreSQL through MS Access. Everything works Ok if I manually connect through Access using the ODBC Dialog. However I wrote a VB function that opens the database and connects to it. This works provided there is no int8 column in the PostgresSQL table. When I use the ODBC interface to link the tables, int8 columns on PostGreSQL are mapped to Number in Access and everything works OK. However when I use connection string as in VB the int8 columns are mapped to Binary in Access. Does anyone know what parameters I need to set in the ODBC string to fix this? I can't find any documentation. There is an Int8 section in the ODBC interface but I cant find any corresponding parameter to set in a connection string. By the way the options I am using in the VB connection string are: "PORT=5432;SSLMODE=prefer;A6=;A7=100;A8=8192;B0=254;B1=8190;BI=8190;C2=dd_;C X=1b503a9" Thanks Andrew ___________________________________________ Andrew J.
