MySQL grant permission question

I want to grant a user delete permission to a database but got issue:

Suppose I have a database: sampleDatabase and a table: sampleTable, and username: sampleUser

What I did was:
grant usage on *.* to 'sampleUser'@'12.1.1.22' identified by password 'xxx';
grant select, insert, update, delete on 'sampleDatabase'.* to 'sampleUser'@'12.1.1.22'

But I still got 'delete permission denied for user: sampleUser@12.1.1.22'

When I specially granted permission to table level, it could work:
grant select, insert, update, delete on 'sampleDatabase'.'sampleTable' to 'sampleUser'@'12.1.1.22'

I have many tables in this database, so I can't grant permission one by one. I didn't experience such issue before when I used '*' to grant permission to all tables in a database.

Any hint? Thanks.

I cannot replicate the problem, but http://stackoverflow.com/questions/3891855/grant-delete-on-database-table-to-username seems to describe the same situation as yours.

Thanks. Still wondering if what the issue is.

When I use:
select * from mysql.db where User = 'xxx' and Host='xxx'
I could see the delete_priviledge is "Y". But when I tried to delete record, it still reported "permission denied". I have to grant delete permission to a table level to delete records.

One thing I notice is: select * from mysql.host returns zero. Does it matter if there is no record in mysql.host table?

Thanks for any hint.

show grants for current_user();
