如何正确的做如下update MYSQL语句？

Question

i have a string with the following value

Germany,Sweeden,UAE

and i have an mysql row that have a value of one of this separated string with comma

as example a Country Row with a value Sweeden.

i have tried to use this sql statement to update a targeted row where its value is like one of this string separated with comma

hence if the row have a value of sweeden it should be updated sense sweeden value is include in the comma string

UPDATE CountryList SET Time= '100' WHERE Country LIKE '%Germany,Sweeden,UAE%' 

but i couldn't update the targeted row using this syntax. any idea what is the correct syntax i should use?

Answer 1

I think you want find_in_set() :

update CountryList 
set time = 100 
where find_in_set(country, 'Germany,Sweeden,UAE')

This checks if country matches any of the values in the comma-separated row given as second argument to find_in_set() .

Note that I removed the single quotes around the literal 100 : if time is a number, then treat it as such (if it's a string instead, then keep the quotes).
