OleDbDataAdapter da = new OleDbDataAdapter[str, conn]; //DataSet ds = new DataSet[]; DataTable dt = new DataTable[]; da.Fill[dt];

}

That's an awfully unusual [and messy] way to be calling the SQL though. It's tough to see if you have further issues. Let me know if it doesn't work and we will figure it out together.

Bonus Tip: Debugging VBA SQL Strings

When you get a VBA run-time error on a line that includes [or references] a complicated SQL string, it can be tricky to determine exactly where the problems lies.

As with troubleshooting any code, the process is to simplify, to eliminate possible culprits.

When attempting to execute the following procedure, we will get a run-time error on the line with the OpenRecordSet method:

Public Function SQLTest[] Dim strSQL As String strSQL = "SELECT * FROM tblMain" & _ "ORDER BY [TableID]" Debug.Print strSQL CurrentDb.OpenRecordset strSQL End Function

To help identify the problem, we can modify the code slightly by adding a single line that will print the value of the SQL string to the Immediate Window.

[Use Ctrl+G to view the immediate window.]

Public Function SQLTest[] Dim strSQL As String strSQL = "SELECT * FROM tblMain" & _ "ORDER BY [TableID]" Debug.Print strSQL CurrentDb.OpenRecordset strSQL End Function

Now, take a look at the output [in the immediate window]:

SELECT * FROM tblMainORDER BY [TableID] ↗↖

It's easy to see that we are missing a space between the table name and the ORDER BY clause, which is simple enough to fix:

strSQL = "SELECT * FROM tblMain " & _ "ORDER BY [TableID]"

• This is the possibly the single most helpful debugging technique for troubleshooting SQL statements in VBA.

• MSDN : Perform Joins Using Access SQL
• TechNet : SQL Joins

EDIT:

Try this to troubleshoot:

Debug.Print "SELECT * FROM [classes] INNER JOIN [students] ON classes.StudentForename = students.Forename AND classes.StudentSurname = students.Surname AND classes.TeacherName ='" & personloggedon.Text & "' AND classes.Day ='" & System.DateTime.Now.DayOfWeek.ToString & "' AND classes.Period ='" & attendance_reg_periodComboBox.Text & "'"  
Stop

Put that code just before the problem line. When the code Stops hit Ctrl+G to view the immediate window.

Copy and Paste the SQL into a new Query Window [in SQL view] and try changing to Design Mode. See if you can identify the error there.

I am trying to modify a form to use a date range instead of a single date.

Here is the original code:

Private Sub cmdprt_Click[] On Error GoTo Err_cmdprt_Click

Dim stDocName As String, stCrit As String
stCrit = "[id]  0"
If Not IsNull[RecStart] And RecStart  0 Then
  stCrit = stCrit & " and [id] >= " & [RecStart]
End If
If Not IsNull[RecEnd] And RecEnd  0 Then
  stCrit = stCrit & " and [id]
