I have a column in a table which used to be varchar(255) in the beginning and due to some design changes now it is varchar(1536) = 1024 + 512. I will not be searching or indexing this field, does it make sense to store this value in a different data type other than a varchar if you would like to optimize this for performance?
Yes, it will be better if you can store the values in the “
TEXT” data type. For more details, please read this article.Regarding knowledge of storage requirements, you can read this one.
Hope it helps.
