Posted 2020-10-03 robert_hly

Dim MyConn As Object
Private Sub ConnectDB()
Set MyConn = CreateObject("ADODB.Connection")    ----->创建连接对象
Dim str As String
str = "DRIVER={mysql ODBC 5.3 Unicode Driver};" & _   ---->拼接连接语句   odbc驱动 
"SERVER=localhost;" & _                         ---->  主机

"PORT=3306;" & _    ----->端口号

"DATABASE=test;" & _   ----->指定数据库
"USER=read;" & _          ------>用户名
"PASSWORD=read;" & _     ------>密码
"Option=3"
MyConn.Open str    ---->打开连接

Dim sql As String
Dim i As Integer

Dim field As String

 

-----------循环开始

For i=1 To 500 

 

field = Worksheets("Sheet4").Cells(i, 5) --->从单元格获取查询条件

 sql = "select delivery_no from tb_table where tb_table.order_id = ‘" & field &"‘"  ----->拼接sql 

Sheets("sheet1").Cells(i, 3).CopyFromRecordset MyConn.Execute(sql)     ----->把查询结果赋值到sheet1第3列

Next i

-------------循环结束

MyConn.Close     ----->关闭连接

End Sub
