How to update mysql column using array

Question

I am working with mysql, I have table "wp_notification" and here is currently strcture of table

id              UserId                PostId              status
1               s:1:"8";              26                  accept          

In "UserId" column, i am saving Userid of users in "array" format using "serialize" function, but now i want to update( add one more user id in this column) this column So how can i do this ? Is this possible with mysql query only ?

Answer 1

You don't need to update the column. You can add one more user id in the future/current cells in that column.

It is worth noting however that using a "serialized" output string as an Id in a database is not a good solution. See Normalization in MYSQL .
