| View as plain text | |||
Aside from the incredibly annoying fact that InnoDB tables don't store a total COUNT(), my question is... Why are these numbers different? I could easily parse out the second query which is REDICULOUSLY faster. BTW, why doesn't mySQL just 'alias' the first query behind the scenes for us and parse out the count? mysql> SELECT COUNT(rsm_report_id) FROM Swordfish.rsm_reports; +----------------------+ | COUNT(rsm_report_id) | +----------------------+ | 277456 | +----------------------+ 1 row in set (24.84 sec) mysql> show table status where Name = 'rsm_reports'\G *************************** 1. row *************************** Name: rsm_reports Engine: InnoDB Version: 10 Row_format: Compact Rows: 296100 <<----- why doesn't this match above?! Avg_row_length: 3204 Data_length: 948961280 Max_data_length: 0 Index_length: 13664256 Data_free: 0 Auto_increment: 277457 <<----- this can't be counted on Create_time: 2007-03-26 20:23:14 Update_time: NULL Check_time: NULL Collation: utf8_general_ci Checksum: NULL Create_options: Comment: InnoDB free: 5120 kB 1 row in set (0.27 sec)
