Question

If i already have record with the exact same data in mysql database i dont want the php code to enter it again.
The code i am using is

mysql_query(" ALTER TABLE tablename ADD UNIQUE INDEX(pageid, name) INSERT IGNORE INTO `tablename`  
VALUES ('2','3','4'));

It doesnt seem to work. What is the problem.

Answer 1

Execute this query from MySQL and create the index first.

ALTER TABLE tablename ADD UNIQUE INDEX(pageid, name);

Then you can perform the insert query from PHP

mysql_query("INSERT IGNORE INTO `tablename`  VALUES ('2','3','4')");
