nothing's wrong with my SQL query. i meant to say the Parameters feature in Access that we use to set up the parameters... once i have set any parameter, that doesn't make any differenc - the criteria remains the same , why's that

Post the SQL for the query.

Ok, I'm still unsure of what your problem is. Right now I'm assuming you have a query and within this query in the WHERE clause you have [Enter Value] or some other type of parameter. This is providing a prompt upon running the query to Enter Value. You enter the value yet the query results remain the same and unfiltered.

Is this accurate? If not I'm going to need you to further explain your problem so I can understand what you're doing and help you get your query functioning properly. Examples are very helpful and maybe some insight into what you are doing.

In either case I still think seeing the SQL would be helpful.

If you open any Query in Design View.
Then goto Menu "Query" then click on "Parameters ". Now you see Query Parameters window.... If you put in any field and close it. Now execute the Query, you will be prompted to enter a value. Query will run but the value you entered would not make any difference - the critera wouldn't change.. why ?

Adding a parameter this way basically just adds a variable to your query. If you want it to filter your query results you will need to use it in your WHERE clause. Now had you posted your SQL in the first place I could have told you this several posts ago. You're right there probably isn't anything wrong with your SQL.

It probably looks something like this:
[code=sql]
PARAMETERS myValue Text (255);
SELECT field1, field2, field3
FROM table1;
[/code]

So your query is functioning just as you have told it to. It gets the parameter and runs your select. You need to tell it what to do with that parameter.

[code=sql]
PARAMETERS myValue Text (255);
SELECT field1, field2, field3
FROM table1
WHERE field1 = [myValue];
[/code]
