Question

When i insert a record into a table, the auto_increment field ‘s value maybe 1000, I know there is a auto_increment counter, deciding the value.

I use the command:

SHOW VARIABLES LIKE 'auto_incre%'

it outputs：

auto_increment_increment    1
auto_increment_offset   1

so I just want to know, if there is a way i can use to check the auto_increment counter value. Thanks for any help.

SHOW TABLE STATUS LIKE 'table_name'

Gives you the column as Auto_increment. This is the next value (often id) which will be added on INSERT.

Example:

$str_table = 'users';

$query = mysql_query("SHOW TABLE STATUS LIKE '{$str_table}'");
$row   = mysql_fetch_assoc($query);

$int_increment = $row['Auto_increment'];
