Trim Postcode (1 Viewer)

[abbaddon223]

Hi all,

If anyone can help I'd be very grateful!

I'm trying to trim a postcode (easy) so that only the first two letters are left (finding not easy).

The issue I have is:

AB21 4LF
S21 2RE

IE I'm after

AB
S

If I trim from left or right based on the a space and characters to remove, the postcodes with only 3 IN characters end up wiped out...

Thanks in advance...

left("S212RE", 2 + ( asc(mid(Ucase("S212RE"), 2,1)) < 64 ) )
S
left("AB214LF", 2 + ( asc(mid(Ucase("AB21 4LF"), 2,1)) < 64) )
AB

should work...

Hi,

Thanks for your response.

Would this work en-masse though? (IE I have 32K lines of data with all different postodes).

Thanks again.

here's another way

i think postcodes have to start with a letter and are either one or two letters for the postcode area.

IIf(IsNumeric(Mid([postcode],2,1)),Left([postcode],1),Left([postcode],2))

assuming your postcodes are guaranteed well formatted then you could use something like this idea - which needs a bit of further attention

if isnumeric(char2) then
   leftpart = left(postcode,1)
else
   leftpart = left(postcode,2)
end if

on reflection i see this is the same idea as G81 above

YEs it should take for any and all postcodes the first (two) letters
