>>How can I easily sort a table based on the primary key?
>>
>>I wrote some FoxPro 6 code a few years ago (now with SP5) and now the client has a fair amount of data in the DB. I would like to resort most (or all) of the tables in that DB based on the primary key of each table.
>>
>>I have spent the last 2.5 hours goofing with SORT, COPY STRUCTURE, APPEND FROM... and combinations there of. In the end all I ended up with was frustration. I am certain that I ran a couple of simple commands when I imported their old data into the 'new' database a few years ago but I just can not seem to figure out the process. Surely, there is an easy way to do this.

>>Any suggestions would be appreciated.
