TRUNCATE TABLE command
Date: July 26, 2007 03:12PM
I was trying to use TRUNCATE TABLE command, and as per certification book MySQL® 5.0 Certification Study Guide,(Section 11.5. The DELETE and TRUNCATE TABLE Statements) it says that Truncate never returns the no. of rows it removed from table, where as to my surprised it did returned the no. of rows but issue is these are NOT the correct rows returned.
Refer to below code
mysql> create table newcity select * from city;
Query OK, 4079 rows affected (0.24 sec)
Records: 4079 Duplicates: 0 Warnings: 0
mysql> truncate table newcity;
Query OK, 3727 rows affected (0.08 sec)
Ideally Truncate table should have returned 4079 instead it returned 3727 rows. Any idea about this issue ?
I am using 5.0.22-community-nt & the table newcity has ENGINE as Innodb
Waiting for reply.
