I have a table Part_Information in which PartNumber is a text field. On a form when user enters PartNumber in textbox I need to check whether that partNumber exists in table or not. I am using Dcount method.
DCount(" PartNumber ", "Part_Information", "PartNumber = " & Me.CurrentPartNumber) = 0
but it gives error 3464 saying data type mismatch in criteria expression.
If PartNumber is a text field, you have to quote the criteria like this:
DCount("PartNumber","Part_Information","PartNumber='" & Me.CurrentPartNumber & "'")

I appreciate some help
I am trying to use Dcount function with 4 criteria
I have a text box in a form to count records on table_orders
The DCount function has 4 criteria:
The ID field in table_orders has to match the Form ID field
The field nature on table_orders has to be null
The field team on table_ordres has to be different than “Canceled”
The field ram (yes/no field) in table_ordes has to be “No”
I´ve been trying in many different ways with no success
This is my last try:
=DCount("*","Table_orders","ID=" & [ID]& " AND IsNull(nature)=true" & " AND [team] <> "Canceled" & AND [ram] ="No")
Try this:
=DCount("*","Table_orders","ID = " & [ID] & " AND [nature] Is Null AND [team] <> 'Canceled' AND [ram] = 'No'")
I am attempting to use Allen Browne's ConcatRelated() function, but I am getting an error of:
Error 3061: Too few parameters. Expected 1
Below is the syntax I input into my query ->
ConcatRelated("Product","[_ProdInfo]","OrderNumber = " & [OrderNumber])
What should I change so that this does not produce the error and displays the results I am after?
Further explanation:
Field Name is Product
Table Name Is _ProdInfo
The field to match on is OrderNumber and it is a short text type
As ConcatRelated() link describe:
If the foreign key field is Text (not Number), include quote marks as
delimiters, e.g.:
"[ForeignKeyFieldName] = """ & [PrimaryKeyFieldName] & """"
And since your OrderNumber is a text field, add the needed quotes:
ConcatRelated("Product", "[_ProdInfo]", "OrderNumber = """ & [OrderNumber] & """)
Or with single quotes:
ConcatRelated("Product", "[_ProdInfo]", "OrderNumber = '" & [OrderNumber] & "'")
I spent some time looking around at other questions on the board, but didn't find anything similar so here it goes:
I have a report that runs up against the limits of CRM 2011 online in regards to the max number of characters in a Fetch Query. I would like to have a drop box that has an option for "All Contacts" or "Select up to Five Contacts" to avoid that issue.
What I would like to do is remove the condition from the Fetch statement if the "All Contacts" option is selected, and include the condition only if the select up to five is chosen.
How would I go about doing this?
Let me know if you have any further questions.

You can build your SQL using custom code because the SQL itself can be a string expression that you build manually. Let's say your SQL looks like this at the moment:
SELECT ThisField, ThatField
FROM Contacts
WHERE ContactId IN #Contacts
Let's change that to a string expression that builds the SQL:
="SELECT ThisField, ThatField "
& "FROM Contacts "
& "WHERE ContactId IN #Contacts "
Now we need to pull the #Contacts parameter apart and only select by ContactId when there are five or less contacts selected:
Function ContactsSQL(ByVal parameter As Parameter) AS String
Dim Result As String
Result = ""
If parameter.IsMultiValue Then
If parameter.Count <= 5 Then
Result = "WHERE ContactId IN ("
For i As integer = 0 To parameter.Count-1
Result = Result + CStr(parameter.Value(i)) + ", "
Next
Result = Left(Result, Result.Length - 2) + ") "
End If
End If
Return Result
End Function
This function builds the SQL WHERE clause to select the contacts only if five or less have been selected, otherwise it passes back an empty string. Now we use this function in our SQL expression:
="SELECT ThisField, ThatField "
& "FROM Contacts "
& Code.ContactsSQL(Parameters!Contacts)
Note that you are passing the Contacts parameter object here, not the Value property. We access the Value property in the custom code function.
I have a form record source set to a elaborate SQL select statement. That is working fine. If it helps to know, the form layout is Tabular. Here is an example of the data:
order carrier billto employee
1 smgd horm chrnic
2 axxm sele chrnic
3 smgd horm redned
4 mcta cron greand
5 mcta cron greand
Its basically unbilled order entries. I want a combo box to show distinct employee names (chrnic, redned, greand) based on the current records showing. I will be coding it to filter the form. Seems simple, but I am having trouble
Things I have tried:
Tried setting rowsource to me.recordsource, but get an
It appears that I would need to parse & edit that string
I copied the complex query & put as combo box record source & that worked to filter the form, so I know that filter logic is correct. I just want it to be dynamic so we only have to change SQL statement in one place if needed
"I have a form record source set to a elaborate SQL select statement."
Save that query as a named QueryDef. I will pretend you chose qryRecordSource as the name.
"I want a combo box to show distinct employee names ... based on the current records"
For the combo box row source use ...
SELECT DISTINCT employee
FROM qryRecordSource
ORDER BY 1;
And then to filter the form based on the combo selection, add a command button, cmdApplyFilter, and use this in its click event procedure ...
Me.Filter = "[employee] = '" & Me.YourComboName.Value & "'"
Me.FilterOn = True
If the employee names can include an apostrophe, use this for the Filter expression ...
Me.Filter = "[employee] = '" & _
Replace(Me.YourComboName.Value, "'", "''") & "'"
If you want to include a combo row to clear the filter, use a UNION query as the combo row source ...
SELECT "*** ALL ***" AS employee
FROM Dual
UNION
SELECT employee
FROM qryRecordSource
ORDER BY 1;
... where Dual is any table or query which returns just one row. Then in the command button click event you can do ...
If Me.YourComboName.Value = "*** ALL ***" Or _
IsNull(Me.YourComboName.Value) Then
Me.Filter = vbNullString
Me.FilterOn = False
Else
Me.Filter = "[employee] = '" & Me.YourComboName.Value & "'"
Me.FilterOn = True
End If
And actually you wouldn't even need the command button. You could set the Filter from the combo's AfterUpdate event.
I have been racking my brain over this all day today.
I have the following ASP code that uses a Request.Querystring input from a dropdown box
to launch a select statement. The querystrinch does show in the ?= URL but will only work on
columns in the Microsoft SQL DB that are numeric. I cant lookup names or simple 3 character fields.
CODE:
If Request.QueryString("m") > 0 Then
filterID = Request.QueryString("m")
filterColmn = "imDegree"
Else filterID = 0
End If
If filterID > 0 Then
SQlQuery = "SELECT * FROM v_InternImport WHERE iID IN (SELECT iID FROM v_InternImport WHERE " & filterColmn & " = " & filterID & ")"
End If
End If
I understand that this select statement as a sub select stament in it but I cant even get a staight reuturn from my DB. The select statement references the same view that populates the main asp page that loads before and the shows fine?
When you pass a string to SQL Server, you need to surround it with single quotes.
When you pass a number, you don't use the quotes.
So, when you say (summarizing)
SELECT * FROM table WHERE filterColumn = filterID
you should be sending a number.
To match a string:
SELECT * FROM table WHERE filterColumn = 'filterID'
This assumes that you have solved any other problems mentioned by the commenters about whether you even have a value in the filterID variable. I heartly concur with the recommendation to use parameterized queries.
Edit: The single quotes go inside the double quotes.
SQlQuery = "SELECT * FROM v_InternImport
WHERE iID IN (SELECT iID FROM v_InternImport
WHERE " & filterColmn & " = '" & filterID & "')"
