vb6.0 连接数据库，查询，插入和修改

一： 创建连接

Public Function CreateSQLConn() As Boolean
Const ProcName = "CreateSQLConn"
Dim strConnection As String
On Error GoTo ErrHandler
1 Set objSQLConn = New ADODB.Connection

2 strConnection = "Provider=SQLOLEDB.1;Password=" & gbServerPWD & ";Persist Security Info=True;User ID=" & gbUserID & ";Initial Catalog=" & gbInitCat & ";Data Source=" & gbServerIP & INSTANCENAME
If RUNSERVER = "REMOTE" Then
strConnection = "Provider=SQLNCLI.1;Password=" & gbServerPWD & ";Persist Security Info=True;User ID=" & gbUserID & ";Initial Catalog=" & gbInitCat & ";Data Source=" & gbServerIP & INSTANCENAME
End If
3 objSQLConn.ConnectionTimeout = 40
4 objSQLConn.Open strConnection
Exit Function
ErrHandler:
ErrLog Erl,Err.Number,Err.Description,ProcName,True,True
End Function

二：查询

Public Function LoadSuppMasterSort(ByVal Sorting As EnSorting) As colGroupMaster
Const ProcName = "LoadSuppMasterSort"
Dim strMSSQL As String
Dim objCol As colGroupMaster
Dim objMSRS As ADODB.Recordset
On Error GoTo ErrHandler
1 Set objCol = New colGroupMaster
2 Set objMSRS = New ADODB.Recordset
3 If Sorting = EnSorting.EnSortByCode Then
4 strMSSQL = "Select SuppCode,SuppName From tblSupplier Order By SuppCode"
5 Else
6 strMSSQL = "Select SuppCode,SuppName From tblSupplier Order By SuppName"
7 End If
8 objMSRS.Open strMSSQL,objSQLConn,adOpenStatic
9 While Not objMSRS.EOF
10 objCol.Add objMSRS("SuppCode"),objMSRS("SuppName")
11 objMSRS.MoveNext
12 Wend
13 objMSRS.Close

三：插入和修改记录

Public Function DoSaveItemmas(ByVal objItemmas As clsItemmas,ByVal InStatus As EnUPDATESTATUS) As Boolean Const ProcName = "DoSaveItemmas" Dim strMSSQL As String Dim objMSRS As ADODB.Recordset Dim strPLU As String Dim blnRet As Boolean On Error GoTo ErrHandler 1 strPLU = Trim(objItemmas.PLU) 2 strMSSQL = "Select * From tblItemmas Where PLU = '" & Trim(strPLU) & "'" 3 Set objMSRS = New ADODB.Recordset 4 objMSRS.Open strMSSQL,1,3 5 If InStatus = EnUPDATESTATUS.EnAddNew Then 6 If Not objMSRS.EOF And Not objMSRS.BOF Then 7 'Find Record To Create and not allow deplicate 8 blnRet = False 9 Else 10 objMSRS.AddNew 11 objMSRS("PLU") = Replace(Trim(objItemmas.PLU),vbCrLf,"") 12 objMSRS("Desci") = Replace(Trim(objItemmas.Desci),"") 13 objMSRS("LongDesci") =
