Passing variables from Form to Query

I would like to have a form with fields in which I can enter strings (which will be used as criteria in queries) and when a button below is clicked, it will step through a number of queries (macro) inserting the appropriate variables into the appropriate query criteria.

Any answers/links/tutorials/keywords to search for would help.

Depending on what you have in mind, the simplest method is to refer directly to the form in your query.  For example, you have a control txt_StartDate on your form, then in your query you could use a syntax like:

SELECT * FROM yourTable WHERE [StartDate] > Forms!YourFormName!txt_StartDate

Problem is that this syntax might not work because Access/Jet might interpret the form value as a string, rather than a date, so you might need to explicitly declare the variable.

PARAMETERS [Forms]![YourFormName]![txt_StartDate] DateTime;
SELECT * FROM yourTable WHERE [StartDate] > Forms!YourFormName!txt_StartDate

Or you might want to simply evaluate the value of the textbox:

SELECT * FROM yourTable WHERE [StartDate] > Eval(Forms!YourFormName!txt_StartDate)

I'm getting an error on this SQL:

SELECT TOP [Forms]![Form1]![Quantity] * INTO DataPull
FROM [Table1]

I'm trying to subsitute the 5100 below with a variable from the form but keep getting an error.

SELECT TOP 5100 * INTO DataPull
FROM [Table1]

Error States: The SELECT statement includes a reserved word or an argument name that is misspelled or missing, or the punctuation is incorrect.

I've triple checked the spelling and it is correct.  Any other ideas?

Sorry, that is one place that you cannot use a variable.

If you want to do something like that, you are going to have to write the SQL on the fly, in the click event of a button or something like that.

Private sub cmd_QueryUpdate_Click

    dim strSQL as string

    strSQL = "SELECT TOP " & me.Quantity & " * INTO DataPull " _
               & "FROM [Table1] ORDER BY Rnd([ID]);"
    currentdb.Execute strSQL, dbFailOnError

End Sub
