我正试图使用insert
命令在数据库中添加一行。
它成功地添加了行,但执行命令后数据库中的旧行被删除了!
Dim connetionString As String
Dim cnn As SqlConnection
Dim cmd As SqlCommand
Dim sql As String
connetionString = "Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Datab1.mdf;Integrated Security=True;User Instance=True"
sql = "INSERT INTO Table1 VALUES ( e , e )"
cnn = New SqlConnection(connetionString)
Try
cnn.Open()
cmd = New SqlCommand(sql, cnn)
cmd.ExecuteNonQuery()
cmd.Dispose()
cnn.Close()
MsgBox(" ExecuteNonQuery in SqlCommand executed !!")
Catch ex As Exception
MsgBox(ex.Message)
End Try
怎么了?
