Table level changed... what does this mean
I have been bugging the list relentlessly for some time now about my
problems with indexing. Briefly, I have a Clipper and a delphi app. that
need to access the same data. The tables if I'm correct are Dbase III+
format. I have at last discovered that one can create indexes using the
addindex method. However when I try to index a table with the following
code:
academic_dbf_tbl.addindex('academic','surname',[ixUnique]);
I get an error 'table level changed'.
If I convert the file to a Dbase 5 format the code works and creates an mdx
file. I would be happy to work mdx indexes, bu t I need my files to stay in
the Dbase III+ format.
An help would be appreciated.
