I'm trying to substring and contat a field to a date format, problem is the string is not always 8 numbers, sometimes it's 7:

1132006 -> 1/13/2006
12132006 -> 12/13/2006

The field is TTXDA

SELECT     TTXDA AS DATE
FROM         TAXTRANS
ORDER BY DATE DESC

I would like the date in 01/13/2006 format, thanks!!

     WHEN 7 THEN  LEFT(TTXDA, 1) + '/' + SUBSTRING(TTXDA,2,2) + '/' + RIGHT(TTXDA,4)

WHOOPS didn't see you wanted 1/13/2006 as 01...

Change WHEN 7... to the following:

WHEN 7 THEN  '0' + LEFT(TTXDA, 1) + '/' + SUBSTRING(TTXDA,2,2) + '/' + RIGHT(TTXDA,4)

Don't forget the leading zero if it's 7 long

SELECT
CASE LEN(TTXDA)
  WHEN 7 THEN '0' + LEFT(TTXDA,1) + '/' + RIGHT(LEFT(TTXDA,3),2) + '/' + RIGHT(TTXDA,4)
  WHEN 8 THEN LEFT(TTXDA,2) + '/' + RIGHT(LEFT(TTXDA,4),2) + '/' + RIGHT(TTXDA,4)
  ELSE NULL
END
