Question

@FromDate datetime = null
@ToDate datetime = null

SELECT * FROM TABLE
WHERE ....
AND [PI].Date BETWEEN @FromDate AND @ToDate

When any date is null, the records are not displayed. What is the correct syntax so that I can get all records if any of the dates are null.

I have thought of this:

@FromDate datetime = '01/01/1901',
@ToDate datetime = '12/31/9999'

Thanks.

Try something like

SELECT * FROM TABLE 
WHERE .... 
AND [PI].Date BETWEEN ISNULL(@FromDate, [PI].Date) AND ISNULL(@ToDate, [PI].Date)
