Question : Update set

I need help with an update set statement

On the field postcode if the len(6) i.e. de34lf, after the 3rd character i need a ' ' so it would be de3 4lf
And if the len(7), i.e. de443lf, after the 4the character i need a ' ' so it would be de44 3lf

How can this be done, rtim and ltrim will be required

Answer : Update set

Karinloos, len only does the rtrim function alone. hence doing ltrim is necessary.

update table
set postcode =
    case len(ltrim(postcode)) when 6 then left(ltrim(postcode), 3) + ' ' + replace(postcode, left(ltrim(postcode), 3),'')
        when 7 then left(ltrim(postcode), 4) + ' ' + replace(postcode, left(ltrim(postcode), 4),'') else postcode
    end


i think this will be sufficient.
