Match comma seperated list with input in SQL statement

Question

Im optimizing my SQL statement to make it faster.

I have a comma seperated list with zipcodes like

1111, 1112,1115,1112 etc etc

Now in my query I want to match if the iput matches 1 of those zipcodes. If so.. then it will return a ID of the object that has all those zipcodes.

But what is the best way to do this now im doing

AND ( loc.loc_zip LIKE  '%".$_REQUEST['zip']."%'

Validation of the input will be added ofcourse.. but this is just for testing. But I have tested this and it seems a bit slow.

Is this the best way to do this ?

Answer 1

you should use 'in'

select * from Users where userid in (1,2,3,4,45,6,656)

Edit: if the ZipCodes are Chars, you can only use in if you separate them by ''

select * from loc where loc.loc_zip in ('1111','1112','1115','1112')

if .$_REQUEST['zip']. has ' ' then->

select * from loc where loc.loc_zip in (.$_REQUEST['zip'].)

if the ZipCodes are int you can use the first statement Bare in mid you must intersect your list with '' or it wont work
