I’m wondering, what is fastest (or lightest for the database to handle)
Let’s say, the db table has 4 fields: x,y,z,q
I only need 3: x,y,q
What way is fastest/easiest for the database to perform (using PHP)..
“SELECT * FROM table” or “SELECT x,y,q FROM table”?
Would the same apply if the table had 5 or more fields while I still only needed to select 3?
SELECT x,y,z FROM tableis faster because MySQL won’t have to look up what columns are in your table before executing the query.
