之前给别人写了个例子:
VB codeDim cnnAsNew ADODB.Connection
cnn.ConnectionString="PROVIDER=MSDASQL;DRIVER={SQL Server};SERVER=192.168.1.100;DATABASE=database1;UID=sa;PWD=123"If cnn.State<> ADODB.ObjectStateEnum.adStateClosedThen cnn.Close
cnn.OpenDim RsAs ADODB.RecordsetSet Rs=New ADODB.RecordsetWith RsSet .ActiveConnection= cnn
.CursorLocation= adUseClient
.CursorType= adOpenKeyset
.LockType= adLockOptimistic
.Open"SELECT good_code,customer,sum(price*amount)/sum(amount) AS avg_price FROM sales GROUP BY good_code,customer"If .RecordCount>0Then
MSFlexGrid1.Clear
MSFlexGrid1.Cols=3
MSFlexGrid1.Rows= .RecordCount+1
MSFlexGrid1.TextMatrix(0,0)="商品编号"
MSFlexGrid1.TextMatrix(0,1)="顾客名称"
MSFlexGrid1.TextMatrix(0,2)="平均价格"

.MoveLast: .MoveFirstFor i=1To .RecordCount
MSFlexGrid1.TextMatrix(i,0)= .Fields(0).Value& vbNullString
MSFlexGrid1.TextMatrix(i,1)= .Fields(1).Value& vbNullString
MSFlexGrid1.TextMatrix(i,2)= .Fields(2).Value& vbNullString
.MoveNextNextEndIf
.CloseEndWithSet Rs=Nothing
