    <p>[Below I am setting the parameters in vba to send to an access query. The query takes a Start Date, End Date, Reason Code and Sub Group. All the criterion are String except for Sub Group which is an integer. </p> <pre><code>Sub FinalDrill() 'Step 1: Declare your variables Dim DatabasePath As String DatabasePath = ThisWorkbook.Path &amp; "\SpreadSheetData.accdb" Dim MyDatabase As DAO.Database Dim MyQueryDef As DAO.QueryDef Dim MyRecordset As DAO.Recordset Dim i As Integer 'Step 2: Identify the database and query Set MyDatabase = DBEngine.OpenDatabase _ (DatabasePath) Set MyQueryDef = MyDatabase.QueryDefs("FinalDrill") 'Step 3: Define the Parameters With MyQueryDef .Parameters("[Start Date]") = GetStartDate() .Parameters("[End Date]") = GetEndDate() .Parameters("[Reason Code]") = "C" .Parameters("[Sub Group]") = 2 End With 'Step 4: Open the query Set MyRecordset = MyQueryDef.OpenRecordset </code></pre> <p>The final line throws "Run-time error 3464" - Data type mismatch in criteria expression</p> <p>I don't get it because i have run this exact type of query from different subs with just the Start Date and End Date and it works a treat.... even is i comment out the</p> <pre><code>'.Parameters("[Reason Code]") = "C" '.Parameters("[Sub Group]") = 2 </code></pre> <p>and change the access query to only except the Start Date and End Date I get the same error. </p> <p>Maybe I'm tired and missing something obvious, any help would be great.</p> <p><strong>UPDATE</strong></p> <p>The below query works so I'm guessing the problem is in my access query.</p> <pre><code>'Step 1: Declare your variables Dim DatabasePath As String DatabasePath = ThisWorkbook.Path &amp; "\SpreadSheetData.accdb" Dim MyDatabase As DAO.Database Dim MyQueryDef As DAO.QueryDef Dim MyRecordset As DAO.Recordset Dim i As Integer 'Step 2: Identify the database and query Set MyDatabase = DBEngine.OpenDatabase _ (DatabasePath) Set MyQueryDef = MyDatabase.QueryDefs("levelOnePie") 'Step 3: Define the Parameters With MyQueryDef .Parameters("[Start Date]") = GetStartDate() .Parameters("[End Date]") = GetEndDate() End With 'Step 4: Open the query Set MyRecordset = MyQueryDef.OpenRecordset </code></pre> <p>Will update with more results once i find them.</p>

    1. COIf you comment date parameters is error still there? I guess that you have problems with dates. Does your function GetStartDate() return date or string value?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
