delete from instrumentos where recno>5633


Well, the syntax looks correct, but ...
Make sure you have a backup in case something goes wrong.

How many records will you be deleting? (if it is a lot consider doing it in smaller batches)

Are there any constraints? (i.e. are other tables affected by this)?

Only you know that database; We only know as much about that db as you have included on this page.

can you provide the complete table definition? (field names, types etc.)

and perhaps a few rows of data too?

If you do not have a [recno] field how do you know that you need to delete where recno > 5633 ?

Are you saying that recno isn't a column from a table? If so, do you want to mean ROWNUMBER?
