Get all records where there are duplicates in 2 fields in one table, returning data from multiple tables.

Hi,

I am using MSSQL2005 and need help to write a SQL statement to achieve the following.

I have 1 tables that I want to create a recordset from.

I want return all records where there are multiple records of any given VENDOR_NO, and for each of those unique VENDOR_NO's there are multiple COST records with the same value.

I hope this is explained clearly.  



What I need is all records where the cost and vendor are the same.

I need this...

VENDOR_NO       COST

AMYS                    2.00
AMYS                    2.00
AMYS                    2.00
BRANDX                4.00
BRANDX                4.00
BRANDX                1.00
BRANDX                1.00

Not this...

VENDOR_NO       COST

AMYS                    2.00
AMYS                    2.00
AMYS                    2.00
BRANDX               2.00
BRANDX                4.00
BRANDX                4.00
BRANDX                1.00
CANDY                  1.00


This SQL statement is working well, however I ran into difficulty adding additional conditions.

Select t.Vendor_no, t.Cost
From   Table t INNER JOIN (
                            Select Vendor_no, Cost
                            From Table
                            Group by Vendor_no, Cost
                            Having COUNT(*) > 1
                          ) m
      On t.Vendor_no = m.Vendor_no and
         t.cost = m.cost


I need to get records where the conditions above are true, and also the BRAND and DEPARTMENT fields from another table are a given value to (to be determined at run time),

(Both tables have ITEM_NO field to match up items)

Thanks in advance,

Ariel

you can create a procedure and call it like this
exec selectvendors 123, 123

create procedure selectvendors 
@yourbrand int,
@yourdepartment int
as
 
Select t.Vendor_no, t.Cost
From   Table t INNER JOIN (
                            Select Vendor_no, Cost
                            From Table
                            Group by Vendor_no, Cost
                            Having COUNT(*) > 1
                          ) m
      On t.Vendor_no = m.Vendor_no and
         t.cost = m.cost
inner join anothertable c on t.item_no = c.item_no
where t.brand = @yourbrand and
t.department = @yourdepartment

Thanks for your reply,

Can you provide an example of how I would call this procedure in my client app?

I am using VB6.  VBA in Excel to be exact.  

Do I need to save this as a stored procedure in MSSQL2005, and then call it somehow in VB?

yes, you have to create above stored procedure in SQL Server 2005 and than call it from VB

Attached is an example of the VBA code. (Make sure you have Microsoft ActiveX Data Objects 2.8 Library checked in Tools->References)
This is using Windows Authentication, but I've also include the SQL authentication code commented out. Just use the one that fits your needs.
So after you create the stored procedure in SQL Server you can call it from your VBA code as indicated below.
You can take a look at this article.
http://www.sqlservercentral.com/articles/Stored+Procedures/63537/

Sub main()
 
' Create a connection object.
Dim cnn As ADODB.Connection
Dim Cmd As ADODB.Command
Dim rst As ADODB.Recordset
 
'Using Windows Authentication
 
    Set cnn = New ADODB.Connection
    cnn.Open "Provider=sqloledb;" & _
    "Data Source=yourservername;" & _
    "Initial Catalog=yourdatabasename;" & _
    "Integrated Security=SSPI;"
 
 
'Using SQL Authentication
'    Set cnn = New ADODB.Connection
'    cnn.Open "Provider=sqloledb;" & _
'    "Data Source=yourservername;" & _
'    "Initial Catalog=yourdatabasename;" & _
'    "User Id=username;" & _
'    "Password=yourpassword"
 
    'Set current sheet
    Range("A1").Activate
 
 
' Define a command object for a stored procedure
    Set Cmd = New ADODB.Command
    Set Cmd.ActiveConnection = cnn
    Set rst = New ADODB.Recordset
    
    Cmd.CommandText = "selectvendors"
 
    
    
    Cmd.Parameters.append Cmd.createparameter("yourbrand", adsmallint, adParamInput, , 123) 
    Cmd.Parameters.append Cmd.createparameter("yourdepartment", adSmallInt, adParamInput, , 123)
 
    Cmd.CommandType = adCmdStoredProc
 
    rst.Open Cmd.Execute
    
    'add headers
    For x = 0 To rst.Fields.Count - 1
        Sheet1.Cells(1, x + 1) = rst.Fields(x).Name
    Next
    
    'result of query
    Sheet1.Range("A2").CopyFromRecordset rst
    
    Set Cmd = Nothing
    cnn.Close
    Set cnn = Nothing
End Sub
