Error: select command denied to user '<userid>'@'<ip-address>' for table '<table-name>'

I'm sure the original poster's issue has long since been resolved. However, I had this same issue, so I thought I'd explain what was causing this problem for me.

I was doing a union query with two tables -- 'foo' and 'foo_bar'. However, in my SQL statement, I had a typo: 'foo.bar'

So, instead of telling me that the 'foo.bar' table doesn't exist, the error message indicates that the command was denied -- as though I don't have permissions.

Hope this helps someone.

database user does not have the permission to do select query.

you can grant the permission to the user if you have root access to mysql

http://dev.mysql.com/doc/refman/5.1/en/grant.html

Your second query is on different database on different table.

 String newSQL = "Select `Strike`,`LongShort`,`Current`,`TPLevel`,`SLLevel` from `json`.`tbl_Position` where `TradeID` = '" + i + "'";

And the user you are connecting with does not have permission to access data from this database or this particular table.

Have you consider this thing?

select command denied to user ''@'' for table ''

This problem is a basically generated after join condition are wrong database name in your join query. So please check the your select query in join table name after database.

Then solve it for example its correct ans ware

string g = " SELECT `emptable`.`image` , `applyleave`.`id` , `applyleave`.`empid` , `applyleave`.`empname` , `applyleave`.`dateapply` , `applyleave`.`leavename` , `applyleave`.`fromdate` , `applyleave`.`todate` , `applyleave`.`resion` , `applyleave`.`contact` , `applyleave`.`leavestatus` , `applyleave`.`username` , `applyleave`.`noday` FROM `DataEMP_ems`.`applyleave` INNER JOIN `DataEMP_ems`.`emptable` ON ( `applyleave`.`empid` = `emptable`.`empid` ) WHERE ( `applyleave`.`leavestatus` = 'panding' ) ";

The join table is imputable and applyleave on the same database but online database name is diffrent then given error on this problem.
