Question

I want to store domain names(example:google.com – without “http://” and “www”)in MySQL as primary key+Index.

so when I call a domain through PHP I should get the result according to that domain faster.
Right now I am inserting domain in plain text.

is it right way to do it?? or do I need to hash it??

your Ideas please

Answer 1

I think you should not use char/varchar in primary index. Rather create an int PK and domain column with unique constraint.

I think that would work in your case.

Checkout some reasons here:

CHAR() or VARCHAR() as primary key in an ISAM mySQL table?

EDIT

Here is the sample table. I created this table on assumptions. Change it according to your need.

CREATE  TABLE IF NOT EXISTS `test`.`sample` (

  `id` INT NOT NULL AUTO_INCREMENT ,

  `domains` VARCHAR(100) NOT NULL ,

  PRIMARY KEY (`id`) ,

  UNIQUE INDEX `domains_UNIQUE` (`domains` ASC) );

P.S. Created using mysql workbench.
