ISNULL() has its own oddities:



DECLARE @var1 char(1)
SET @var1 = NULL

SELECT ISNULL(@var1, 'N/A') -- Result = 'N'

Prosecutor James Blackburn, in closing argument in the "Fatal Vision" murders trial: "If in the future, you should cry a tear, cry one for them [the murder victims]. If in the future, you should say a prayer, say one for them. And if in the future, you should light a candle, light one for them."

Yes, the data type for isnull is always the type of the first argument.
