Field '' not found

[Robson]

We sometimes get the error "Field '' not found". The strange thing is, it only occurs every once in a while. And it occurs on a number of QueryDataSets. There are no fields added with the fieldeditor and the query always returns the same columns. Also the table structure doesn't change. Furthermore, the fields are all fetched via FieldByName without use of variables for the name. Any idea what the problem might be?

We use:

Delphi 5
Direct Oracle Access 346
Oracle 9.2

I'm not sure what could cause this. We haven't had similar problem reports before. If you have a reproducible case, feel free to send it by e-mail so that we can check it out.

It happend, when some part of code has set to dataset a new sql query text, which does not contain the specified field (which is in datasets default sql text and is regulary added to his fields)
