MYSQL Truncated incorrect DOUBLE value

Question

When the SQL query below is executed:

UPDATE shop_category 
SET name = \'Secolul XVI - XVIII\' 
    AND name_eng = \'16th to 18th centuries\' 
WHERE category         


        

Answer 1

It seems mysql handles the type casting gracefully with SELECT statements. The shop_id field is of type varchar but the select statements works

select * from shops where shop_id = 26244317283;

But when you try updating the fields

update stores set store_url = 'https://test-url.com' where shop_id = 26244317283;

It fails with error Truncated incorrect DOUBLE value: '1t5hxq9'

You need to put the shop_id 26244317283 in quotes '26244317283' for the query to work since the field is of type varchar not int

update stores set store_url = 'https://test-url.com' where shop_id = '26244317283';
