判断一个字段是否在表中
Function BlnField(sTblName As String, sFldName As String) As Boolean

sTblName　源表名
要查找的字段名

Dim fld As Field
Dim rs As DAO.Recordset

BlnField = False
Set rs = CurrentDb.OpenRecordset(sTblName)
rs.Fields.Refresh
For Each fld In rs.Fields
If fld.Name = sFldName Then
BlnField = True
Exit For
End If
Next
rs.Close
Set rs = Nothing
Set fld = Nothing
End Function

Private Sub 命令0_Click()
返回True则有此字段，False则无
MsgBox BlnField("tbl1", "ID")
End Sub
