不好意思,整段代码如下:
Dim i, sql
Dim rs As New ADODB.Recordset, cn As New ADODB.Connection
Set cn = New ADODB.Connection
Set rs = New ADODB.Recordset
If = "" Then
MsgBox "只有输入了合同号,才能进行查询!", vbOKOnly, "提示"
Exit Sub
End If
If rs.State = adStateOpen Then rs.Close
sql = "SELECT A.hth, A.pf, B.ylpf, B.ylsh, B.cgfs, Sum(B.dh*A.sl) AS yyl FROM A INNER JOIN B ON (A.hth = B.hth) AND (A.pf = B.pf) GROUP BY A.hth, A.pf, B.ylpf, B.ylsh, B.cgfs where A.hth='" & & "' ORDER BY A.pf ASC "
cn.CursorLocation = adUseClient
cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.Path & "\test.mdb;Jet OLEDB:Database Password=;Persist Security Info=False;"
rs.Open sql, cn, 1, 1
Set Me.DataGrid1.DataSource = Nothing
Set Me.DataGrid1.DataSource = rs
