SSRS 2012表达式生成器Today（）错误

Question

I have two SSRS Parameters, Date/Time type: BeginDate and EndDate. I want them to default to EndDate=Today() and BeginDate=Today()-six months. Using Report Parameters, Default Values, I add a value and create the function =Today() but I get the red squiggly line under the parens.

If I select the function from the Category list and double click it into the "Set Expression for:Value" box, I get the function with a single open-paren and the red squiggly which remains if I close off with a close-paren.

I get the same error if (following the example in the "Example" section, for crist's sake) of =DateAdd("m", -6, Today()) I get the same error instead of a date six months prior.

A little help please...?

Thanks

Answer 1

The problem is that you are using SQL command syntax but Reporting Services uses VBA.

Even though the examples show Today() with the brackets after it, as if it was a method, that actually displays as a syntax error for me in the expression editor. Today's date is simply accessed like a property:

=Today

DateAdd exists but uses DateInterval properties, not the SQL "m" so six months ago is:

=DateAdd(DateInterval.Month, -6, Today)
