' 用excel SQL方法
'conn是建立的连接对象，用open打开
' 通过 CreateObject("ADODB.Connection") 这一句建立了一个数据库连接对象conn
' 在工程中就不再需要引用“Microsot ActiveX Data Objects 2.0 Library“对象
'设置对象 conn 为一个新的 ADO 链接实例,也可以用 set conn = New ADODB.Connection。
--------------
' conn.Close表示关闭conn连接
' Set conn = Nothing 是把连接对象conn置空，不然你退出了文件，但数据库还没有关闭
conn.Open "dsn=excel files;dbq=" & ThisWorkbook.Path & "\001.xls"
'dsn是缩写，data source name数据库名是 excel file
'Sql = "select sum(分数) from [sheet1$]"这里加"分数"两字什么作用?
'
'SQL一般结构是select 字段 from 表，意思是从指定的表中查询字段，字段的理解可以是：表中的列名
'
'分数是001.xls文件的sheet1第一行A列的字段名，SQL一般以字段来识别每列数据
'-------------------
'为什么要用复制的对象引用过来计算呢？
'
'因为Sql语句只是对源数据库的字段找到了符合条件的的数据，但不会自动复制到汇总表来，所以需要复制copy
'
'注意这里的 [sheet1$]" ，001文件的数据存放地上sheet1表，应当用方括号并加上$
'
'如果源数据文件001不是excel，而是Access，则引用表时，不需要加方括号，也不要$
