Select row when value is in range - sql

Question

Given the two column below how can I select the row 110-118 if my filter is 111? 100-118 is a range thus 111 falls between 100-118
Dest_ZIP Ground
004-005 003
009 005
068-089 002
100-118 001

Answer 1

Below is a simple example of how to do this in SQL using a sub query to get the start and end range. This can be expanded on to better handle parsing the string value.
Declare #Temp TABLE
(
Dest_Zip varchar(7),
Ground varchar(3)
)
INSERT INTO #Temp VALUES ('004-005','003')
INSERT INTO #Temp VALUES ('068-089','002')
INSERT INTO #Temp VALUES ('100-118','001')
SELECT A.Dest_Zip, A.Ground FROM
(
select
Convert(int, SUBSTRING(Dest_Zip,1,3)) StartNum,
Convert(int, SUBSTRING(Dest_Zip,5,3)) EndNum,
*
from #Temp
) AS A
WHERE 111 >= A.StartNum AND 111 <= A.EndNum

Answer 2

Fix the data. Here is a simple way using computed columns (and assuming the "zips" are always 3 characters):
alter table t
add column minzip as (left(dest_zip), 3),
add column maxzip as (right(dest_zip), 3);
Then, you can run the query as:
select t.*
from t
where '111' between t.minzip and t.maxzip;
You can even create an index on computed columns, which can help performance (although not much in this case).

If you wish to make the checks in php, maybe this sample code can help you:
<?php
$my_string = "111";
$foo = "100-118"; // our range
$bar = explode('-', $foo); // Get an array .. let's call it $bar
// Print the output, see how the array looks
//print_r($bar);
//echo $bar[0].'<br />';
//echo $bar[1].'<br />';
if(($bar[0] <= $my_string ) AND ($bar[1] >= $my_string)){ echo 'true';} else { echo 'false';}
?>
