i have a data flow configured to use a ole db source. the ole db source uses an ole db connection manager pointing to the adventureworks db which suceeded when i tested its connection. the data access mode of the ole db source is "sql command". below is the sql command text:
SELECT SpecialOfferID, Description
DiscountPct, Type, Category, StartDate,
EndDate, MinQty, MaxQty, ModifiedDate
FROM Sales.SpecialOffer
WHERE ModifiedDate >= ? AND ModifiedDate < ?
this query uses 2 paramaters, each of which is mapped to a datetime variable which falls with the range of the ModifiedDate column as follows:
Parameter0: User::ExtractStartDate
Parameter1: User::ExtractStopDate
ExtractStartDate is set to 7/1/2001 and ExtractStopDate is set to 3/31/2004. however, i get the following error when i press the preview button in the ole db source editor: "there was an error displaying the preview. additional information: no value given for one or more required parameters (microsoft sql native client)".
as far as i can tell, i have the ole db source configured correctly. thus, i can't figure out why this error is being generated. has anyone else experienced this issue? if so, were you able to resolve it? is this a bug?
thanks in advance.
Hi Duane, once you use parameters in your query, the query will not be able to parse or preview. It's a pretty normal hassle you'll get used to :).

Not sure it's really either. It was the same way in DTS. Essentially the provider can't parse the literal query. Probably the ultimate answer is to perform the preview and parse like Reporting Services does where it pops open a box asking for the variable values you'd like to parse. As it stands, SSIS or DTS doesn't have enough info to perform a parse.
