Dim insert_coupon_query As String = ("INSERT INTO qa_discountcoupons (id, status_code) VALUES (AUTO_INCREMENT_ID, 5)")
Dim cmd_query As New MySqlCommand(insert_coupon_query, objConn)
Dim cmd_result As Integer = CInt(cmd_query.ExecuteScalar())
我想返回当前插入的 AUTO_INCRMENT 值，并显示在消息框中。
您可以使用双重查询并使用该函数最后插入 ID() http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_last-insert-id运行第一个查询后获取最后一个当前查询：
Dim insert_coupon_query As String = ("INSERT INTO qa_discountcoupons (status_code) VALUES (5); SELECT LAST_INSERT_ID()")
Dim cmd_query As New MySqlCommand(insert_coupon_query, objConn)
Dim cmd_result As Integer = CInt(cmd_query.ExecuteScalar())
MsgBox(cmd_result)
