Last Modified: 2015-04-21
Hello Experts:

I want to insert values in database table where the values doesn't exist... I am trying to write the code using PDO / PHP / mysql.

I am reading values from same database table and inserted in same database...

Due to the limitations of the web application, I can add unique key in the table and use INSERT IGNORE MYSQL technique... I have to go with IF NOT EXIST technique...

Please let me know if anybody has done this before.
