13.4.1 Comment vérifier une table

To check a table, use the following commands:

isamchk nom_table

This finds 99.99% of all errors. What it can't find is corruption that involves ONLY the data file (which is very unusual). If you want to check a table, you should normally run isamchk without options or with either the -s or --silent option.

isamchk -e nom_table

This does a complete and thorough check of all data (-e means ``extended check''). It does a check-read of every key for each row to verify that they indeed point to the correct row. This may take a LONG time on a big table with many keys. isamchk will normally stop after the first error it finds. If you want to obtain more information, you can add the --verbose (-v) option. This causes isamchk to keep going, up through a maximum of 20 errors. In normal usage, a simple isamchk (with no arguments other than the table name) is sufficient.

isamchk -e -i nom_table

Like the previous command, but the -i option tells isamchk to print some informational statistics, too.
