Last Modified: 2012-05-12
hello all,

in a java project i would like to check a database user if he has right of change database structure. (such as drop_priv, alter_priv, delete_priv)

the first question is: how do i check the drop right of  'myuser' , who has localhost as host.
here some details:
in mysql, i have tried to use
select Delete_priv from mysql.user where User='myuser';
to find if use has delete right. but the result i got is "Yes" and "No". because in database there are two users with the same name, one has "localhost" as host, another has "%" as host.  

second question is: how do i get the result of sql above in java code?

do you mean that you are happy with your sql, you just want to know how to get it in the java code?

If so, then you need to use JDBC

If  your question is different, please, elaborate

You probably want the following and you can get the result in java by using this in the usual way, as any other query
select user from mysql.user where user = 'myuser' and host = 'localhost' and drop_priv = 'Y';
