The default is 8196, so it has to be increased.) For what it is worth, Postgresql has a 1 Gb limit on the size of a text field. So if you know that you ascii chars are 8bits, then you should be able to store a little over 134,000,000 characters. > Conclusion: Version 8.2.4.0 of psqlodbc30a.dll and psqlodbc30w.dll > require tables WITH OID. > (The "OID Options, Show column" -- and presumably > "ShowOidColumn" -- has > no effect.) I will try to spend some time to play with ADO record sets without using a DSN to see what happens and see with I can comeup with. But in the mean time at least you can perform your test comparison.
