The forum will experience an outage sometime between February 10 at 7:00pm EST and February 12 at 11:59 EST for installation of security updates. The actual time and duration of the outage are unknown but attempts will be made to minimize the downtime. We apologize for any inconvenience.

When using UNION I receive "Cannot convert '' to a timestamp" when I try to run something like this:

select [field1], [field2] from [table]


select [field1], '' from [second table];

Field1 is the same in both tables. In the first select statement field2 data type is timestamp but I don't want field2 pulled from the second select statement. Is there a way to cast or format field2 in the second statement to run in this instance?

Appreciate any assistance.

Try NULL instead of ''.
