Some time When we import the large database file then shows the errors like as below:
1 errors were found during analysis.
Missing expression. (near "ON" at position 25)
SQL query: Edit Edit
SET FOREIGN_KEY_CHECKS = ON;
MySQL said: Documentation
#2006 - MySQL server has gone away
The solution of this problem is to change the php.ini values as below:
max_execution_time = 500
max_input_time = 500
memory_limit = 512M
post_max_size = 512M
max_allowed_packet = 512M
Now restart the services… hope it will work.
