   I was not able to get the query to work with CheckPlus, either with all   
   fields changed from Check to CheckPlus or else just the JobItem fields.

   I do not get an answer table, but the default block size of the BDE is 4096.

   That table has 115 rows and JobItem.DB has 1050412 records. The issue is   
   that if Whs1.db has only a single JobKey in all of its rows, the query will   
   run successfully. When a second JobKey is added, then the error occurs. I do   
   not believe table size is an issue here because this query will only use a   
   small number of the JobItem records, at most a few hundred.   
      
   I am now getting more interactive information since I added the answer   
   table. "Corrupt file - other than header." Table: JobItem.db   
   File:JobItem.px. However, the PX file is not corrupt. It has been rebuilt   
   with both Chimney Sweep and alternately with TUtility. A TUtility verify   
   reports a BTree error, and Chimney Sweep reports no errors. I do not believe   
   this table is corrupted because the data is heavily used elsewhere and there   
   is no erroneous data reported. I think this is related to this query.   
      
   Thanks,   
   Joe
