Hi, I'm using HDBC extensively in my app and it works very well. Most of the time my app uses an Sqlite database with HDBC and no problems there. The only problem I have is when I use it against an Access database backend in which I want to do inserts. Creating a connection works fine, also running queries. It only budges when I want to do inserts. *RedcomBatch.Export> handleSqlError $ run dbc "insert into mytable values (?)" [toSql "dummytext"] *** Exception: user error (SQL error: SqlError {seState = "[\"HY104\"]", seNativ eError = -1, seErrorMsg = "bindparameter 1: [\"98: [Microsoft][ODBC Microsoft Ac cess Driver]Ung\\252ltiger Genauigkeitswert. \"]"}) *RedcomBatch.Export> Any ideas why? Günther The German part of the error message reads "invalid precision value"
