John, As long as you don't need to update the data in the view coming from SQL, you can setup a stored procedure with parameters in SQL, then use a pass-through query in your Access front end to call the stored procedure and pass it the parameters. For example, say you have a table in SQL called tblMyInfo with fields: MyInfoID, SomeData1, SomeData2 Create a new stored procedure with parameters as in the following example: CREATE PROCEDURE [ap_GetMyInfo] @GetMyInfoID integer AS SELECT MyInfoID, SomeData1, SomeData2 FROM tblMyInfo WHERE MyInfoID = @GetMyInfoID GO Then in your pass through query in Access, setup your connection string to your SQL database(in the properties of the query) and call the stored procedure in the SQL ie: ap_GetMyInfo 6 When you run the pass-through query, you get a list of records that have a MyInfoID value of 6 HTH Rusty -----Original Message----- From: JWColby [mailto:jwcolby at colbyconsulting.com] Sent: Wednesday, February 21, 2007 1:11 PM To: 'Access Developers discussion and problem solving' Subject: Re: [AccessD] Feeding parameters to SQL Server Well... I dunno. I have a view in SQL Server returning 8 fields, 6K records (currently), completely unfiltered, all records in the table. I pull that linked table into a query in order to do some preliminary filtering - check date between a pair of dates and check number not null. I want the view in sql server to do the "check number not null" for me, and I know how to do that. I want the SQL Server to take a pair of parameters - "From Date" and "To Date" and return only those records. If I could do this, then I could get rid of my "base query" in access which applies these filters, reduce traffic across the wire etc. However even if I do this, the view is not being requested by a form in XP (for example) where some magical thing happens in Access to pass the parameters off to SQL Server. The linked view will be used immediately in another query which joins this view to other tables (on one field - BEID - in the view) in order to build up a set of data for a report. So the "parent" query that is using the view will have to "feed" the parameters to the linked view. Being a nubee to SQL Server I do not even know if what I am attempting to do is possible. I cannot wrap my mind around how a query that is using a view can know that the view needs parameters, and if it did, what to feed it. If it is possible, I have never done so obviously, so I don't even have the basics of what to set in Access to do the parameter passing. John W.
