Row Count Discrepency

2006-01-01, 7:23 am

I have an InnoDB table in a MySQL 4.1.14 database. Can anyone suggest
why MySQL Adminstrator says the table has 497 rows, while doing a query or
a count on the same table shows that it only has 434?

IIRC, InnoDB only gives an estimated row count in admin (or SQLyog or
whatever), not an actual count, because of the way it does (or doesn't)
store row information.

MyISAM tables, on the other hand, show accurately because they store the
rowcount as part of the table data.
