If you merely want to use and open the the query itself you might want to consider using a function to pass back values to your parameter query. Your form code could set the criteria and pass this to a global variable. A Function could pick up on that global variable and pass the value to the query.

Use the SetParameter method to create a parameter for use by the BrowseTo, OpenForm, OpenQuery, OpenReport, or RunDataMacro methods.

Syntax

expression.SetParameter (Name, Expression)

expression A variable that represents a DoCmd object.

When the Query Parameters window appears, enter the two parameters Start Date and End Date, and select Date/Time as the data type. Click on the OK button. Click on the OK button. Now, when you run the query, you will be prompted to enter the 'start' date. Return All Records When a Query Parameter Is Blank. The Input box when the query is executed If a value is entered into this input box, the query will return only the results that contain this value: The results of running the query with East Midlands as the parameter value If. Access Query. PARAMETERS startDate DateTime, endDate DateTime; SELECT WarehouseCode, COUNT(DeliveryPoint) AS Som FROM 50 resultaat WHERE EntryDate between startDate and endDate GROUP BY WarehouseCode; This is working fine. However, I am now trying to use the same code to call a passthrough query to a SQL server. This form collects three parameters for the parameter query qryAlbumsPrm2. Choose the type of music from the combo box and the range of years to include in the two text boxes. Click on the OK button to execute the parameter query using the parameters collected on the form. From the query, going into Data Connections (group) Connections (button) Properties brings up the Connection Properties dialogue box which shows a Parameters button, however this is always grayed out. Most of the guides online say to use an 'Other Data Source', which isn't an option in this version. Apr 30, 2018  The parameters are defined in the query. I am trying to execute the query from a button click on a form. There will be 4 buttons on the form and each one will send different parameters to the query to execute.

Parameters

Name	Required/Optional	Data type	Description
Name	Required	Variant	The name of the parameter. The name must match the name of the parameter expected by the BrowseTo, OpenForm, OpenQuery, OpenReport, or RunDataMacro method.
Expression	Required	Variant	An expression that evaluates to a value to assign to the parameter.

Remarks

You must create as many calls to the SetParameter method as are necessary to create the parameters you need.

Microsoft Access Query Prompt

Each call to SetParameter adds or updates a single parameter in an internal parameters collection. The parameters collection is passed to the BrowseTo, OpenForm, OpenQuery, OpenReport, or RunDataMacro method. When the method is run, the parameters collection supplies the needed parameters. When the method is finished, the parameters collection is cleared.

Because each of the methods that accepts parameters clears the parameters collection when it completes, you must ensure that your calls to SetParameter immediately precede the call to the method that employs them.

Example

The following code example creates two parameters for use by the AddComment data macro. The two parameters are named prmComment and prmRelatedID, respectively. The value of the txtComment text box is stored in the prmComment parameter. The value of the txtId text box is stored in the prmRelatedID parameter.

This is a part one of two-part on how you can make your queries much more powerful. In first part, we look at whether we’re in or not. Part two can be found here.

The IN clause is a great tool to have in your arsenal, it can allow your forms to be editable or filter forms using .

What is the IN clause?

The IN clause is a member of the SQL language syntax and can be used in your WHERE clause to specify which data to include or exclude. (There are other uses too, as discussed here).

Two Syntax Alternatives

You can use the IN clause by specifying the criteria to include in your query. For example, let’s say you want a list of all orders in IL, WI and MN. You could do it this way:

Microsoft Access Query Parameter Drop Down Box

SELECT *
FROM tblOrders
INNER JOIN tblCustomers
ON tblOrders.CustomerID = tblCustomers.CustomerID
WHERE tblCustomer.CustomerState = 'IL'
OR tblCustomer.CustomerState = 'WI'
OR tblCustomer.CustomerState = 'MN';

The problem with the above statement is adding a ton of states makes for a long SQL Statement. Instead you can use the IN clause as a shortcut for the equivalent expression above:

SELECT *
FROMÂ tblOrders
INNER JOIN tblCustomers
ON tblOrders.CustomerID = tblCustomers.CustomerID
WHERE tblCustomers.CustomerState IN('IL','WI','MN');

Power Up

But what if you don’t want orders from those states? You can combine IN with NOT like this:
SELECT *
FROMÂ tblOrders
INNER JOIN tblCustomers
ON tblOrders.CustomerID = tblCustomers.CustomerID
WHERE CustomerState NOT IN('IL','WI','MN');

Super Charge

The above examples are great ways to use the IN clause, but you can Super Charge your code by using a select statement instead of listing values like this:
SELECT *
FROM tblOrders
WHERE CustomerID IN(
SELECT CustomerID
FROM tblCustomers
WHERE CustomerState IN('IL','WI','MN')
);

Notice how I dropped the INNER JOIN from my SELECT statement and instead I’m using the IN clause to retrieve all orders for those customers who belong in the states in question.

Use IN to query on tables not in the select statement

There are many situations where you need to avoid a JOIN on your select, here are two:

• You need users to edit data in your form and using a JOIN will make it read only.
• One or more tables are not stored together. For example: the Order table might be on SQL Server and the Customer table stored locally in Access. Such a join would be slow and not optimal.

Use IN to filter your form

One of my favorite techniques is to filter a form using the WHERE clause of the DoCmd.OpenForm statement. For example, the other day I was building a dashboard for a banking client that included a count of delinquent loans in the system. I made the number clickable, allowing users to launch the frmLoans form with the list of delinquent loans with the following line:

DoCmd.OpenForm _
FormName:='frmLoans', _
WhereCondition:='LoanID IN(SELECT LoanID FROM vw_DelinquentLoans)'

Note that the data is contained in a SQL Server view that’s linked in Access front-end. Instead of joining the view which may cause sub-optimal performance, the IN clause ensure that the list of LoanIDs is evaluated once.

Use IN to avoid duplicates in your queries that has a GROUP BY clause

Many times you will have a query that contains a GROUP BY clause for which you need unique records, but you are getting multiple records due to joins with other tables. Consider using the IN clause instead of joining on one or more tables.

So are you IN or are you OUT?
