mysql - 将 mysql 查询转换为在 vb.net 中使用

Question

我是 mysql 和 vb.net 的新手，有以下查询:

select `db_employee`.`firstName` as `firstName`, `db_employee`.`lastName` as `lastName`,
       `tbl_employment`.`position` as `position`
  from (`db_employee` `db_employee`
  inner join `tbl_employment` `tbl_employment` on (`tbl_employment`.`ctrlID` = `db_employee`.`ctrlID`))
 where (`tbl_employment`.`companyName` like 'MES%') 

我想将其转换为此处使用:

Dim MySqlConn = New MySqlConnection
MySqlConn.ConnectionString = connStr
Dim SDA As New MySqlDataAdapter
Dim dbdataset As New DataTable
Dim bsource As New BindingSource
MySqlConn.Open()
Dim query As String
query = ?

您可以使用下面的代码来显示数据...我希望这是您想要的..:)

Dim cn As SqlConn= New SqlConn("Connecting String")
    Dim cmd As sqlCommand
     Dim dr As sqlDataReader
cn.open()
cmd = New sqlCommand("select * from table or your query, cn)
            dr = cmd.ExecuteReader()
            dr.Read()
            textbox1.Text = dr(1).ToString()
cn.close()
