I'm using CASE and CAST to convert a field to datetime format so that I can account for null field values
CASE
WHEN ISDATE([Date])=0 THEN 01/01/1900
ELSE
CAST([Date] as datetime)
END as [DateConverted]
How can I use this new [DateConverted] field in the criteria of my query so that I can only get records in a specific date range?
