#1062 - Duplicate entry 0' for key 'PRIMARY'

问题

INSERT INTO `crm_customer` (`customerid`, `firstname`, `lastname`, `address`, 
  `telephoneno`, `companyname`, `fax`, `comments`, `countryid`, `statename`, 
  `cityname`, `emailaddress`, `zipcode`, `dateofbirth`, `unsubscribe`) 
VALUES ('0', 'jhghjgfk', 'kghjkj', 'hjkghjgh', '8776785', 'hjghjkgyjk', 
     '457665', 'jghjgfhj', '0', 'ghjgfjgf', 'gjgfhj', 'ghjgfhjgfj', 
     '764574576', '2017-03-13', '')

I'm getting error as `#1062 - Duplicate entry 0' for key 'PRIMARY'

If you have an auto increment column you don't need the value for key primary .. assuming you key primary is customerid you should use:

    INSERT INTO `crm_customer` ( `firstname`, `lastname`, `address`, 
  `telephoneno`, `companyname`, `fax`, `comments`, `countryid`, `statename`, 
  `cityname`, `emailaddress`, `zipcode`, `dateofbirth`, `unsubscribe`) 
VALUES ( 'jhghjgfk', 'kghjkj', 'hjkghjgh', '8776785', 'hjghjkgyjk', 
     '457665', 'jghjgfhj', '0', 'ghjgfjgf', 'gjgfhj', 'ghjgfhjgfj', 
     '764574576', '2017-03-13', '')

Simply avoid the column name and value in the corresponding part of the insert.

Or, you can use it in column name list but with null value:

    INSERT INTO `crm_customer` (`customerid`,  `firstname`, `lastname`, `address`, 
  `telephoneno`, `companyname`, `fax`, `comments`, `countryid`, `statename`, 
  `cityname`, `emailaddress`, `zipcode`, `dateofbirth`, `unsubscribe`) 
VALUES ( null, 'jhghjgfk', 'kghjkj', 'hjkghjgh', '8776785', 'hjghjkgyjk', 
     '457665', 'jghjgfhj', '0', 'ghjgfjgf', 'gjgfhj', 'ghjgfhjgfj', 
     '764574576', '2017-03-13', '')

And, if you don't have auto increment add it:

 ALTER TABLE crm_customer MODIFY COLUMN customerid INT auto_increment

I assume customerid is your primary key and you are trying to make duplicate entry for the same customerid.

Try this

INSERT INTO `crm_customer` ( `firstname`, `lastname`, `address`, 
  `telephoneno`, `companyname`, `fax`, `comments`, `countryid`, `statename`, 
  `cityname`, `emailaddress`, `zipcode`, `dateofbirth`, `unsubscribe`) 
VALUES ('jhghjgfk', 'kghjkj', 'hjkghjgh', '8776785', 'hjghjkgyjk', 
     '457665', 'jghjgfhj', '0', 'ghjgfjgf', 'gjgfhj', 'ghjgfhjgfj', 
     '764574576', '2017-03-13', '');

And if customerid is not autoincremented set, then set it by,

ALTER TABLE crm_customer AUTO_INCREMENT = 1

This will work if and only if you already have primary key in your table.
