VALID Varchar Values
-
Hello All,
I have a field in one of my tables (Delivery_Area) defined as a varchar(10) and it's part of a primary key which is erroring with duplicate key issue...here is what the fields pkey data looks like? So, my question, is '-' DASH a VALID varchar value? It's as if the value is being truncated at the DASH...hope this is not too confusing
delivery_no + date + delivery_area
11 02/02/05 A
12 02/02/05 A-night
Pulled from BOL...
The char and varchar data types store data composed of:
· Uppercase or lowercase characters such as a, b, and C.
· Numerals such as 1, 2, or 3.
· Special characters such as the "at" sign (@), ampersand (&
, and exclamation point (!). char or varchar data can be a single character, or a string with a maximum of 8,000 characters.
Thanks...Marsha

from what you wrote, it looks like you need varchar(20) and not (10)
it truncates at the tenth char and these two would then be identical

Thanks for the prompt reply but here are the datatypes of the composite PK...so, the TOTAL size of the PK is 20 + characters...
delivery_number varchar(10)
delivery_date smalldatetime
delivery_area varchar(10)
you are saying that it will ONLY use the value of varchar(10) for the PK?
Thanks...Marsha

um, no, and I never beat my wife either.
there's nothing special about the dash (or any other character) unless it is stripped by your client process on loading. So take a close look at everything.
If you think the dash is a problem then you should be able to recreate it in a temp table with two rows and create the index on that and see if it fails. That would be a bug so huge as to have been found by almost everyone.

Thanks...I wasn't able to make it fail, it had no problems with the '-' dash as a VALID varchar value...I will send this one back to the developers to take a look at their application coding.
Thanks for your assistance and advice...Marsha
