mysql (5.1) > create table with name from a variable

Question

I\'m trying to create a table with a name based on the current year and month(2011-09), but MySQL doesn\'t seem to like this.

SET @yyyy_mm=Year(         


        

Answer 1

You should be able to do something like this:

SET @yyyy_mm=DATE_FORMAT(now(),'%Y-%m');
SET @c = CONCAT('CREATE TABLE `survey`.`',@yyyy_mm, '` LIKE `survey`.`interim`');
PREPARE stmt from @c;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

Answer 2

set @yyyy_mm=concat(year(now()),'-',month(now()));
set @str = concat('create table survery.`', @yyyy_mm,'` like survey.interim;');
prepare stmt from @str;
execute stmt;
deallocate prepare stmt;
