I was checking mysql by mistake i updated the (max_questions =1) .
Now i searched over google and stack overflow for this solution every one has a answer like ,
UPDATE mysql.user SET max_questions=0 WHERE User='root';
SET CHARACTER SET 'utf8'; SELECT @@character_set_client;
GRANT USAGE ON *.* TO 'root'@'localhost' WITH MAX_QUERIES_PER_HOUR 0;
but no one is giving the answer that where to execute these query because phpmyadmin is showing this error
Error
SQL query: Edit Edit
SET CHARACTER SET 'utf8';
MySQL said: Documentation
the error shows
check the manual that corresponds to your MySQL server version for the right syntax to use near '=0 where user='root' at line 1 – asif Aug 01 '15 at 10:11
