CHECKSUM TABLE tbl_name[,tbl_name ...] [ QUICK | EXTENDED ]
Reports a table checksum. If
specified, live table checksum is reported, or
NULL if the table does not support live
checksum. This is very fast. In
the whole table is read row by row and the checksum is
calculated. This can be very slow for large tables. By default -
EXTENDED - MySQL returns live checksum if the
table support it and scans the table otherwise.
Este comando está implementado no MySQL 4.1.1.
