OK, here's my scenario: We have a client with a database app where the backend data resides in MS SQL server and the frontend was created with MS Access 97. Eventually they will be migrating to a Web/PostgreSQL system, but it will be done in two steps. The first is to change the backend to PostgreSQL. I imported the data from the MS SQL server into a Access MDB file. Then I broght it back to our office to work with. I tried various methods to try to transfer the data from Access97 into postgres, finally I gave up and decided to write something myself. I set up two ODBC datasources, the .mdb file and the Postgres Database; then I wrote a small Python script to pull records out of the one and insert them into the other. Worked like a charm. Now I am trying to link the frontend (in Access97) to PostgreSQL through ODBC. I have 6 tables, 3 of them have no problems, but the other 3 will not let me change any data. I can view it, but when I try to change something, it gives me this error message: "This has been changed by another user since you started editingit. If you save the record, you will overwrite the changestheother user made. Copying the changes to the clipboard will let you look at thevalues the other user entered, and then paste the changes backifyou decide decide to make changes." There are three buttons: "Save Record", "Copy to clipboard", and "Drop changes". "Save Record" is greyed out. In the logs I get: conn=50895320, query='BEGIN' conn=50895320, query='UPDATE "agents" SET "eocoverage"='1' WHERE "agentid" = '381966990' AND "firstname" IS NULL AND "middleinitial"IS NULL AND "lastname" IS NULL AND "spouse" IS NULL AND "idtype" = 'FID' AND "dob" IS NULL AND "homeaddress"IS NULL AND "homecity" IS NULL AND "homestate" = 'MI' AND "homezip" IS NULL AND "homeareacode" IS NULL AND"homephone" IS NULL AND "email" IS NULL AND "agencyname" = 'A W Ayres Agency' AND "agencypobox" = '278' AND "agencyaddress"= '700 W Chicago Rd' AND "agencycity" = 'Sturgis' AND "agencystate" = 'MI' AND "agencyzip" IS NULL AND "agencyareacode"= 616 AND "agencyphone" = '6511761' AND "agencytollfreecode" IS NULL AND "agencytollfreenumber" IS NULL AND"agencyfaxareacode" = 616 AND "agencyfax" = '6513264' AND "agencycontact" IS NULL AND "agencycontact2" IS NULL AND "dedicatedfax"= '1' AND "eocoverage" = '0'' conn=50895320, query='ROLLBACK' All six tables have primary keys. In the 'Agents' table, 'agentid' is the primary key. I have tried every combination of options for the PsqlODBC driver I can think of. None of them work. I tried turning on "Recognize Unique Indexes", "Row Versioning", "OID Show Columns", "OID Fake Index", etc. No combination seems to work. I had this problem once with the MySQL ODBC driver on some other computers. In that case, updating to the latest driver fixed the problem. I have installed the latest version of everything. PostgreSQL 6.5.3, psqlODBC 6.40.0008, MS MDAC 2.5. I just can't figure it out. ,------------------------------------------------------------, | Weston J.
