I use an InterBase database with an alias made in BDE. I want to display the record number for a table when I navigate through the records.
Your solution >.RecNo always returns –1 because it is a TDataSet.RecNo.
Is there another solution?
There is no such thing as a record number with server-based databases such as InterBase and others like SQL Server and Oracle. This is because these database servers are set-based, not record-based. RecNo only applies to desktop databases like Paradox and dBASE (and clones).
You might be able to “fake” the record number with your table if you have a unique identifier in that table, and that unique identifier is a single column. In that case, you’d do something like this:
SELECT Count(UniqueIDColumn)FROM MyTableWHERE UniqueIDColumn
where IDValue is the ID value of the current "record." Of course, you'd have to know that with some sort of retrieval SQL statement.
