Hi,
I have data coming from the source with words having Mix case(e.g MiKe)...I need to compare the word with a hash file lookup that contains a word(e.g MIKE)...with a normal match i am not able to do that...how do i achieve the same using DS.?

Regards,
SM

The UPCASE() function will convert to uppercase pretty efficiently, do that with both strings and you are in production

Yes Arnd,
Thats pretty simple...but the actual requirement is to restore the data with the original mix case characters...

Thanks,

Could you explain? Your post states you want to do a match with one uppercase string to a mixed case string, the UPCASE() function lets you do that. So you now have the original string , an uppercased string and a true/false result on a match - what more do you need?

In short,
for comparison have UPCASE(Src.Name)=UPCASE(Lkp.NAME), but while writing the field, dont do any transformation, simple one to one mapping(do not change case)

You can use the UpCase function in the Key Expression of the hash lookup for the comparison, but not UpCase the field as it goes to your target.

Hope this helps.

You can pass your source link value to the target to retain mixed case.

Yes I can do an Upcase in the Hashfile Key Expression column...but what about my source file...for e.g in hash file I have "John" and the source file I have "JOHn" as input...how do I compare using hash file compare?

Please suggest.

Thanks,

Make the acutal key to your Hash file an uppercase name, create a temporary column in your job with the uppercase lookup name and use that as the lookup key to your hash file.

Or simply use UpCase function in the link to reference.
