PHPMyAdmin - 总记录数不同 [英] PHPMyAdmin - Total record count varies
问题描述
我使用phpmyadmin在一个记录表上运行请求,结果计数不同。例如,当显示结果时,显示显示记录1 - (〜180,234)。
此数字每次刷新时都会更改,并且不会添加或删除任何数据。
当我对记录执行SQL请求时,结果保持不变。这是phpMyAdmin的问题吗?
I am running a request on a table of records with phpmyadmin, and the results count varies. For example, when showing the results it says "Showing records 1 - (~180,234 )".
This number changes each time I refresh, and no data is being added or removed.
When I do a SQL request for the record, the result stays the same. Is this an issue with phpMyAdmin?

在InnoDB表的
情况下返回一个近似计数。参见
$ cfg ['MaxExactCount']一个到
的方法来修改这些结果,但这可能会对性能造成严重的影响。
phpMyAdmin uses a quick method to get the row count, and this method only returns an approximate count in the case of InnoDB tables. See $cfg['MaxExactCount'] for a way to modify those results, but this could have a serious impact on performance.
