I am getting the following error every time I try to run a particular piece of code:
Run-tim error '3075' Syntax error (missing operator) in query expression

The code is below.

I am thinking it must be something simple that I left out or did wrong, but for the life of me I can't find it!

Dim frm As Form
Dim ctl As Control
Dim db As DAO.Database
Dim strsql As String
Dim i As Variant

Set frm = Forms("f_SubTaskAssignments")
Set ctl = frm![lstExistingAssignments]
Set db = CurrentDb

For Each i In ctl.ItemsSelected

strsql = "DELETE FROM SubTaskAssignment WHERE " & _
        "[TaskOrderID] = " & ctl.Column(0, i) & " AND [SubTaskID] = " & ctl.Column(5, i) & " And [CompanyID] = " & ctl.Column(6, i) & " And [PersonID] = " & ctl.Column(7, i) & " And [ReportAs] = " & ctl.Column(4, i)
            
db.Execute strsql, dbFailOnError
ctl.Requery
Next i

CurrentDb.Execute strsql, dbFailOnError

End Sub

Pretty sure the problem is that you cannot use the Column() property for a Combo or List box in a query (SQL).

Do any of those columns contain string/text values? If so, then you need to single-quote the data that you are sending in your query.

So, you would need to use a variable to get those values ... and then use that variable(s) in the SQL statement.

Do this test to see what number your are getting:

MsgBox VarType(ctl.Column(0, i))

Most likely, you will get 8 (string). So you need to convert it to integer like
Clng(ctl.Column(0, i)) in this case

With the exception of the last piece of data, they are all numbers. The last part:

And [reportAs] = " & ctl.column(4, i)

is text. At least, the data in column 4 is text.

How do I write that with single-quotes?

The columns references are picking up the right data. When I hover over them with my curser, the correct numbers and text are showing.

if SubTaskID is text, then try:

...  " AND [SubTaskID] = '" & ctl.Column(5, i) & "' ...

eghtebas: tried it and it isn't working. I am getting the same error.

"Most likely, you will get 8 (string). So you need to convert it to integer like
 Clng(ctl.Column(0, i)) in this case" - Do I do this with each one of the columns that involves a number?

DatabaseMx:

"So, you would need to use a variable to get those values ... and then use that variable(s) in the SQL statement."  - Do you mean that I would have to dim a variable for each column and then set each one equal to the actual column (ctl.column(0,i)?  I am not sure about this and I have used this type of code in the past. The statement is picking up the data from the form. Are you sure that would be the problem?

I probably should have just written all of this out. The complete error reads as follows:


Syntax error in string in query expression '[TaskOrderID] = 783 AND [SubTaskID] = 156 AND [CompanyID] = 776 AND [PersonID] = 4080 AND [ReportAs] = Delete after test'.

In your table (SubTaskAssignment), do you have:

[TaskOrderID] Long
[SubTaskID] Long
[CompanyID] Long
 [PersonID] Long
 [ReportAs] Text

Sorry if you have mentioned before, just want to be sure. 8 was as expected. I will wait for your response for the above 5 items.

"The statement is picking up the data from the form. Are you sure that would be the problem?"

If you try to use Forms!SomeForm!SomeCombo.Column(3) in a query, it will fail to execute.

"Do you mean that I would have to dim a variable for each column and then set each one equal to the actual column (ctl.column(0,i)? "

Pretty much ... looks like five variables ...

However, it's possible the Execute SQL  handles this different that running from the query grid - and referencing the Column property.

Your code has some messes in it

Dim frm As Form
Dim ctl As Control
Dim db As DAO.Database
Dim strsql As String
Dim i As Variant

Set frm = Forms("f_SubTaskAssignments")
Set ctl = frm![lstExistingAssignments]
Set db = CurrentDb

For Each i In ctl.ItemsSelected
'ok great starting a loop

'Composing the SQL String to execute

strsql = "DELETE FROM SubTaskAssignment WHERE " & _
        "[TaskOrderID] = " & ctl.Column(0, i) & " AND [SubTaskID] = " & ctl.Column(5, i) & " And [CompanyID] = " & ctl.Column(6, i) & " And [PersonID] = " & ctl.Column(7, i) & " And [ReportAs] = " & ctl.Column(4, i) 'here you may need quotes if this is a string value

'execute the deletions  
 db.Execute strsql, dbFailOnError      

'hey wait a second!  You're still in the loop.  Why are you requerying the listbox
ctl.Requery

'looping back to nail the next record
Next i

'you're done the loop.  Why do this again?
CurrentDb.Execute strsql, dbFailOnError

End Sub

If ctl.Column(4, i) is string data then

strsql = "DELETE FROM SubTaskAssignment WHERE " & _
        "[TaskOrderID] = " & ctl.Column(0, i) & " AND [SubTaskID] = " & ctl.Column(5, i) & " And [CompanyID] = " & ctl.Column(6, i) & " And [PersonID] = " & ctl.Column(7, i) & " And [ReportAs] = " & chr(34) & ctl.Column(4, i) & chr(34)


Ought to get it done.

Try making this change:


& " And [ReportAs] = " & Chr(34) &  ctl.Column(4, i) & Chr(34)

because that column is returning Text

it's possible the Execute SQL  handles this different that running from the query grid

It'll go.
It's a listbox, and a multiselect one to boot, not a combobox.
She's composing a complete SQL string and then executing it.
As long as it's syntax correct, it'll work.

That totally worked! Adding the Chr(34) around the last item fixed it.

I also made the other recommendations you suggested, Nick67. Thank you so much!!!!!!
