Description
The CHECK TABLE command checks the integrity of a table and its indexes and memo file, where applicable.
If the optional REPAIR keyword is specified:
- Any detected index errors are auto repaired.
- Any detected duplicate links in the memo file are unlinked.
The CHECK TABLE command can be run on shared data.
After execution the "_tally" system variable is set to the number of errors detected.
Example
open database southwind
check table customers
if _tally > 0
check table customers repair
endif
