case statement using cast

Hi guys,

The value in the field ACCOUNTS.ACCOUNTKEY is something like: '3130005'

I need to read the characters from position 4 to 6. If the value of that Substring is equal to the VALUE Zero then write "Zero".

In the code below, the first "case" is working nice, but the second (red one) is getting ERROR.

Please Help.

"SELECT ACCOUNTS.ACCOUNTKEY," _
& " Case When SUBSTRING(ACCOUNTS.ACCOUNTKEY, 4, 3)= '000' then 'Zero'" _
& " Case When CAST(SUBSTRING(ACCOUNTS.ACCOUNTKEY, 4, 3) as int) =0 then 'Zero'" _
& " Else 'Unknown'" _
& " End " _
& "AS 'Finding Zero' "
Thanks in advance,

Aldo.

Hi,

What is the errormessage?

Is it possible that there are non-nummeric values at these positions?

the data in the field is a string containing nummeric characters...

I solved the problem using the code below:

SLC = "SELECT ACCOUNTS.ACCOUNTKEY AS 'X'," _
& " Case " _
& " When CAST(SUBSTRING(ACCOUNTS.ACCOUNTKEY, 4, 3)as int)= 0 then 'Zero'" _
& " When CAST(SUBSTRING(ACCOUNTS.ACCOUNTKEY, 4, 3)as int)>= 1 " _
& "And CAST(SUBSTRING(ACCOUNTS.ACCOUNTKEY, 4, 3)as int)<= 699 then 'Non-Zero'" _
& " Else 'Unknown'" _
& " End " _
& "AS 'Clasifying Values', "

The ERROR in the code I uploaded earlier was using the word "Case" in both cases:

... Case When ...

...Case When...

instead of:

... Case

When

When

This code is working too:

sqlString = "SELECT ACCOUNTS.ACCOUNTKEY AS 'X'," _
& " Case " _
& " When SUBSTRING(ACCOUNTS.ACCOUNTKEY, 4, 3)= '000' then 'Zero'" _
& " When SUBSTRING(ACCOUNTS.ACCOUNTKEY, 4, 3)>= '001' And SUBSTRING(ACCOUNTS.ACCOUNTKEY, 4, 3)<= '699' then 'Non-Zero'" _
& " Else 'Unknown'" _
& " End " _
& "AS 'Clasifying Values' "

I'll be glad to learn some other good idea.

Thanks,

Aldo.|||Just an FYI, this is a transact-sql question, not an SSIS question. To tie this into SSIS, you could avoid doing the case statement in your SQL and do it in a derived column transformation.
