After you have __connected__ to the database using IB_SQL, what dialect is being reported on the Connection tab?

No. If you have __actually__ got a dialect 3 database, a column defined as DATE will be a dialect 3 DATE type. If your database is in fact a dialect 1, a column defined as DATE will be the equivalent of TIMESTAMP.

What EXACTLY is the error message?

In the Data Definition manual, the section on datatypes.

What kind of control are you trying to view the blob column in? A TDBGrid? AFAIK, the VCL TDbGrid doesn't support displaying blobs in a grid. Display a TDBMemo alongside the grid, linked to the same datasource and to the blob datafield; then, as you scroll through the grid you will see the contents of the blob field.

NB, make sure that you instantiate the virtual field objects of your dataset (set the query Active, then dbl-click on the iboquery, right-click on the window and select Add All Fields.) Select the blob field and, if necessary, change its FieldType to ftMemo.

No, the DBGrid must be linked through its Datasource property to a TDatasource. This TDatasource in turn must be linked to your dataset through its Dataset property. Or is this what you meant?
