一、抓到 datagridview
Dim sqlstr As New String("SELECT 年度薪資.姓名, 年度薪資.員工編號" & _
" FROM where year(年度薪資.發薪日期)=" & TextBox1.Text & " group by 年度薪資.姓名, 年度薪資.員工編號 ;")
Dim da As New SqlDataAdapter(sqlstr, MDIParent1.conn)
Dim cb As New SqlCommandBuilder(da)
da.Fill(Data)
DataGridView1.DataSource = Data
二、reader 一筆一筆讀取
Dim sqlquery As String
sqlquery = "select count(姓名) from 考核獎金 where 年度='" & TextBox1.Text & "' and 次數='" & TextBox2.Text & "';"
Dim cmnd As SqlCommand = New SqlCommand(sqlquery, MDIParent1.conn)
Dim reader As SqlDataReader
reader = cmnd.ExecuteReader()
While (reader.Read())
If reader.IsDBNull(0) = False Then
havedata = reader.GetValue(0)
End If
End While
reader.Close()
