Do you have example code that fails? Mysql variables are probably limited
to your server's max_packet value. I am able to create variables containing
long strings with no problems, at least:
mysql> set @a=repeat('a',1024*1024*10);
Query OK, 0 rows affected (0.95 sec)
mysql> select length(@a);
+------------+
| length(@a) |
+------------+
| 10485760 |
+------------+
1 row in set (0.05 sec)
mysql>
