Concatenate Query

D

Dean Fraiquin

Hi,

I have a database with Company info, and a Products table
that is joined by unique client ID.

A new table is created which has one record for each
product listing the unique client ID.

I want to create a query whereby lt looks at the client
ID and creates a single field of all products seperated
by a comma and space. Now I've look around the web, and
it seems possible but I do not really understand the SQL
stuff. The query currently looks like this:

SELECT Services.ID, Services.[Client ID], Services.
[Product/Service]
FROM Services;

What additional text do I need to input to make my dreams
come true???

Many thanks for any help.

You can use a generic function. Copy the below code into a new module and
save it as "basConcatenate". Then, you can use it in a query as noted in the
code.

Function Concatenate(pstrSQL As String, _
Optional pstrDelim As String = ", ") _
As String
'example
'tblFamily with FamID as numeric primary key
'tblFamMem with FamID, FirstName, DOB,...
'return a comma separated list of FirstNames
'for a FamID
' John, Mary, Susan
'in a Query
'SELECT FamID,
'Concatenate("SELECT FirstName FROM tblFamMem
' WHERE FamID =" & [FamID]) as FirstNames
'FROM tblFamily
'

'======For DAO uncomment next 4 lines=======
'====== comment out ADO below =======
'Dim db As DAO.Database
'Dim rs As DAO.Recordset
'Set db = CurrentDb
'Set rs = db.OpenRecordset(pstrSQL)

'======For ADO uncomment next two lines=====
'====== comment out DAO above ======
Dim rs As New ADODB.Recordset
rs.Open pstrSQL, CurrentProject.Connection, _
adOpenKeyset, adLockOptimistic
Dim strConcat As String 'build return string
With rs
If Not .EOF Then
.MoveFirst
Do While Not .EOF
strConcat = strConcat & _
.Fields(0) & pstrDelim
.MoveNext
Loop
End If
.Close
End With
Set rs = Nothing
'====== uncomment next line for DAO ========
'Set db = Nothing
If Len(strConcat) > 0 Then
strConcat = Left(strConcat, _
Len(strConcat) - Len(pstrDelim))
End If
Concatenate = strConcat
End Function

Duane,

Thanks for the code - I have copied it into a module and
named it and placed it in the query - however when I try
to run it it asks for Paramenter values of the pstrSQL
and the pstrdelim - i'm quite new at this so I have no
idea what to do - further advice would be greatly
appreciated!

Many apologies for not getting it, but I am trying.

Here is the SQL as it stands:

[Product/Service], Concatenate([«pstrSQL»],[«pstrDelim»])

You must provide a parameters like:
Concatenate("SELECT ....")
You mention company and products tables but all I see is one table named
services. Your final query would have only a source table of company.
Select tblCompany.ClientID, Concatenate("Select [Product/Service] From
tblProducts p where P.ClientID = tblCompany.ClientID) as Products
From tblCompany;

You need to provide a legitimate SQL string in the function. The FROM clause
expects a table or query name.

SELECT id, Concatenate("SELECT [Product/Service] From [Services] WHERE
[Client ID] = " & id) as Products From [Main Data];

BTW: you would be much better off in the future if you don't use punctuation
and spaces in object names. You should find a comfortable naming convention
and stick with it.

Duane,

Thanks for the example - I have amended the SQL as
follows:

SELECT [Main Data].id, Concatenate("SELECT
Product/Service From [Services].Product/Service WHERE
[Services].Client ID = [Main Data].id") as Products
From [Main Data];

However, when I try to run it, I get the following
statement: Run-time error '-2147217900 (80040e14)'
Syntax error in FROM clause

And when I hit debug - the following is highlighted:

rs.Open pstrSQL, CurrentProject.Connection, _
adOpenKeyset, adLockOptimistic

Apologies for keeping on, but I'm not that experienced
with SQL and VBA etc.

Many thanks,

Dean

Hi Dean and Duane,

I too have been frustrated by similar concatenation problems.

As an alternative to Duane's solution I'm posting another function.

The following function code has served me well although I cannot claim
to have generated it myself--its from another forum from some time back.

'************ Code Start **********
Function fConcatChild(strChildTable As String, _
strIDName As String, _
strFldConcat As String, _
strIDType As String, _
varIDvalue As Variant) _
As String
'Returns a field from the Many table of a 1:M relationship
'in a semi-colon separated format.
'
'Usage Examples:
' ?fConcatChild("Order Details", "OrderID", "Quantity", _
"Long", 10255)
'Where Order Details = Many side table
' OrderID = Primary Key of One side table
' Quantity = Field name to concatenate
' Long = DataType of Primary Key of One Side Table
' 10255 = Value on which return concatenated Quantity
'
Dim db As Database
Dim rs As Recordset
Dim varConcat As Variant
Dim strCriteria As String, strSQL As String
On Error GoTo Err_fConcatChild

varConcat = Null
Set db = CurrentDb
strSQL = "Select [" & strFldConcat & "] From [" &
strChildTable & "]"
strSQL = strSQL & " Where "

Select Case strIDType
Case "String":
strSQL = strSQL & "[" & strIDName & "] = '" &
varIDvalue & "'"
Case "Long", "Integer", "Double": 'AutoNumber is Type Long
strSQL = strSQL & "[" & strIDName & "] = " & varIDvalue
Case Else
GoTo Err_fConcatChild
End Select

Set rs = db.OpenRecordset(strSQL, dbOpenSnapshot)

'Are we sure that 'sub' records exist
With rs
If .RecordCount <> 0 Then
'start concatenating records
Do While Not rs.EOF
varConcat = varConcat & rs(strFldConcat) & "; "
.MoveNext
Loop
End If
End With

'That's it... you should have a concatenated string now
'Just Trim the trailing ;
fConcatChild = Left(varConcat, Len(varConcat) - 2)

Exit_fConcatChild:
Set rs = Nothing: Set db = Nothing
Exit Function
Err_fConcatChild:
Resume Exit_fConcatChild
End Function

names fields returned as one and the results can be sorted.
