Parameters Collection Object

A collection of Parameter objects for the specified query table. Each Parameter object represents a single query parameter. Every query table contains a Parameters collection, but the collection is empty unless the query table is using a parameter query.

Using the Parameters Collection

Use the Parameters property to return the Parameters collection. The following example displays the number of parameters in query table one.

MsgBox Workbooks(1).ActiveSheet.QueryTables(1).Parameters.Count
		

Use the Add method to create a new parameter for a query table. The following example changes the SQL statement for query table one. The clause “(city=?)” indicates that the query is a parameter query, and the value of city is set to the constant “Oakland.”

Set qt = Sheets("sheet1").QueryTables(1)
qt.Sql = "SELECT * FROM authors  WHERE (city=?)"
Set param1 = qt.Parameters.Add("City Parameter", _
    xlParamTypeVarChar)
param1.SetParam xlConstant, "Oakland"
qt.Refresh
		

You cannot use the Add method on a URL connection query table. For URL connection query tables, Microsoft Excel creates the parameters based on the Connection and PostText properties.
