Hi,

The issue is that you are trying to trim and change case on a date time field. You need to cast/convert the date time to a char field before you can change the format. I am not sure what you were trying to achieve with making a date in uppercase?

If you are looking at trimming the timestamp from the date, you could convert to char then substring the 10 characters that make up the date component....

The other part in this derived column expression is what datatype is the result writing to? Assuming from your error that it is still expecting a timestamp output.

Not sure if that helped - but I am not sure what you are trying to achieve.

Just an update -
Change your datatype to a DT_STR length 10

ISNULL(BLOOM_ISSUE_DT) ? "1900-01-01" : (DT_STR,10,1250)(BLOOM_ISSUE_DT)

This will set null dates to your 1900 date, the string convert looks at first 10 characters and uses the ANSI code page 1250 for character set decode - but choose the one that suits you.
