MyBB SQL Error

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
    1 - Can't create/write to file '/tmp/#sql_4ec6_0.MYI' (Errcode: 122)
Query:
    SHOW COLUMNS FROM mybb_users LIKE 'unreadpms' 

Please Tell me How Can I fix It Now?
Please Explain Step By Step

I get error 144. 144 - Table './techworm_db/mybb_datacache' is marked as crashed and last (automatic?) repair failed

Enter PHPMyADMIN, find the table, and repair it. That should fix it.

Table 	Op 	Msg_type 	Msg_text
techworm_db.mybb_datacache 	repair 	error 	Can't create new tempfile: './techworm_db/mybb_dat...
techworm_db.mybb_datacache 	repair 	status 	Operation failed

CAN i empty the table?

No you don't want to empty your table. Just Repair it.

That's host issue Mark, the first error showing its not writing to the database table. Means either host dis-able it or admi9n doesn't allow permissions / privileges while creating user / password for the database.
