Hello all, There is a new odbc driver (version 6.30.0237) and source code at our website (http://www.insightdist.com/psqlodbc). This one contains some bug fixes AND alot of setup options! You can now configure the driver more closely to match your needs hopefully. Please click on the version link and/or the "dialog boxes" link for more detailed information. Some quick highlights are: - By democratic vote, uses ISO datestyle, period! Automatically sets this datestyle to backend on connection. - Advanced options for Driver and Datasource (and lots of them). - Ability to control whether cursors are used, thus emulating the old driver/libpq behavior. - Ability to control how unknown sizes are reported: "Longest" emulates old driver/libpq behavior. - Recognizing Unique indexes is a driver option. - Some data type mappings and data type sizes are configurable. - SQLExtendedFetch implemented when not using cursors. There is also a "Defaults" button to set all these options back to optimum settings. Note, there are performance issues involved with not using cursors, since the driver must suck down all the rows in the result set. However, there are some advantages when it comes to updating tables since the tables are not kept locked by the backend. If you are having problems with locked tables or the driver hanging, try setting Use Cursors to false. This is a workaround until whenever the backend locking improves. Also, when not using cursors, the sizes of character data types varchar and text can be known since all the tuples are retrieved in the result set. So if you set the option "Longest" on the Advanced Options (Driver), this will be possible. Feedback on this new driver is appreciated. Regards, Byron.
