Error Code 1292 - Truncated incorrect DOUBLE value - Mysql

Question

I am not sure what is this error!

#1292 - Truncated incorrect DOUBLE value: 

I don't have double value field or data!

I have wasted a whole hour trying to figure this out!

here is my query

INSERT INTO call_managment_system.contact_numbers 
    (account_id, contact_number, contact_extension, main_number, created_by)
SELECT
    ac.account_id,
    REPLACE(REPLACE(REPLACE(REPLACE(ta.phone_number, '-', ''), ' ', ''), ')', ''),'(','') AS Phone,
    IFNULL(ta.ext, '') AS extention,
    '1' AS MainNumber,
    '2' AS created_by
FROM 
    cvsnumbers AS ta
    INNER JOIN accounts AS ac ON ac.company_code = ta.company_code
WHERE 
    LENGTH(REPLACE(REPLACE(REPLACE(REPLACE(ta.phone_number, '-', ''), ' ', ''), ')', ''),'(','') ) = 10

here is my show create table for the table which the results are going into

CREATE TABLE `contact_numbers` ( ?
    `number_id` int(10) unsigned NOT NULL AUTO_INCREMENT, ?
    `account_id` int(10) unsigned NOT NULL DEFAULT '0', ?
    `person_id` int(11) NOT NULL DEFAULT '0', ?
    `contact_number` char(15) NOT NULL, ?
    `contact_extension` char(10) NOT NULL DEFAULT '', ?
    `contact_type` enum('Primary','Direct','Cell','Fax','Home','Reception','Office','TollFree') NOT NULL DEFAULT 'Primary', ?
    `contact_link` enum('Account','PDM','Other') NOT NULL DEFAULT 'Account', ?
    `status` tinyint(1) NOT NULL DEFAULT '1' COMMENT '0 = inactive, 1=active', 
   ?`main_number` tinyint(1) NOT NULL DEFAULT '0' COMMENT '1 = main phone number', ?

Answer 1

This message means you're trying to compare a number and a string in a WHERE or ON clause. In your query, the only potential place where that could be occurring is ON ac.company_code = ta.company_code; either make sure they have similar declarations, or use an explicit CAST to convert the number to a string.

If you turn off strict mode, the error should turn into a warning.
