Hi,

I have a table of Locations around the country. My system produces reports
based on these Locations. I also have a table containing Brick Codes e.g.

Brick Post Code
AB51 AB51
AB52 AB52
AB55 AB55
AB56 AB56
AL01 AL1
AL02 AL2
AL03 AL3
AL04 AL4

How can I compare the first 3 or 4 letters of the postcode in the Locations
table to the corresponding entry in the Brick Codes table so I can add it to
my report?

Thanks for your help

Use the substring function to get the n letters and the case
function to compare, such as ...

case when substring(brick,1,2) = substring([post code],1,2) then 'matching
1st 2' else 'no match' end "Comparison 1 of x",
case when substring(brick,1,3) = substring([post code],1,3) then 'matching
1st 3' else 'no match' end "Comparison 2 of x",
case when substring(brick,1,4) = substring([post code],1,4) then 'matching
1st 4' else 'no match' end "Comparison 3 of x",
etc

Shaun,

This is untested, but should do the trick.

WHERE Brick = CASE LEN(PostCode)
WHEN 3 THEN STUFF(PostCode,3,0,'0')
ELSE PostCode END

or

WHERE PostCode = CASE SUBSTRING(Brick,3,1)
WHEN '0' THEN STUFF(Brick,3,1,'')
ELSE Brick END

Hope that helps,
Rich
