Question

I have one small question, I am new so please help me.

In my project I have one text file which has zip4 and zip5 , I want to concatenate both the zip code but it has one problem, at some place zip4 is blank (not null) so when I used the derived column with

ISNULL(ZIP_4) ? ZIP_5 : (ZIP_5 + "-" + ZIP_4) 

expression it will return the

(zip5-)

where zip4 is blank and I want only zip5 without -.

So please help me.

Answer 1

Try

ISNULL([ZIP_4]) || LEN([ZIP_4]) == 0  ? [ZIP_5] : ([ZIP_5] + "-" + [ZIP_4]) 

or

ISNULL([ZIP_4]) || LEN(RTRIM(LTRIM([ZIP_4]))) == 0  ? [ZIP_5] : ([ZIP_5] + "-" + [ZIP_4]) 

Second one will trim zip_4 both sides before checking its length.
