mysql - ColdFusion:查询中有多个 SQL 语句？

Question

显然，ColdFusion 不喜欢在单个查询中使用多个 SQL 语句...所以曾经是这样的:

SET @sender_user_id = 3, @recipient_user_id = 5;

INSERT INTO messages (message_type, sender_id, message_title, message_content) 
  VALUES(3, @sender_user_id, 'One more thing...', 'I am testing this message');

SET @saved_message_id = LAST_INSERT_ID();

INSERT INTO message_recipient (message_id, user_id) 
  VALUES(@saved_message_id, @recipient_user_id);

INSERT INTO message_status (message_id, user_id, is_read, read_datetime, is_deleted, deleted_datetime)
  VALUES (@saved_message_id, @recipient_user_id, 0, NULL, 0, NULL);

Get 变成了这样:

<cftransaction>

    <cfquery name="insertMessage" dataSource="mySource">

        SET @sender_user_id = 3, @recipient_user_id = 5;

    </cfquery>
    <cfquery name="insertMessage2" dataSource="mySource">

        INSERT INTO messages (message_type, sender_id, message_title, message_content) 
        VALUES(3, @sender_user_id, '#params.message_title#', '#params.message_content#');

    </cfquery>
    <cfquery name="insertMessage3" dataSource="mySource">

        SET @saved_message_id = LAST_INSERT_ID();

    </cfquery>
    <cfquery name="insertMessage4" dataSource="mySource">   

        INSERT INTO message_recipient (message_id, user_id) 
        VALUES(@saved_message_id, @recipient_user_id);

    </cfquery>
    <cfquery name="insertMessage5" dataSource="mySource">   

        INSERT INTO message_status (message_id, user_id, is_read, read_datetime, is_deleted, deleted_datetime)
        VALUES (@saved_message_id, @recipient_user_id, 0, NULL, 0, NULL);

    </cfquery>

</cftransaction>

这行得通...但我想知道是否有一些我不知道的 ColdFusion 东西。否则，这有效。

在 ColdFusion Admin 中，转到数据源定义表单并将“allowMultiQueries=true”添加到“连接字符串”框中。完成后，您可以在单个 CFQUERY 标记中传递多个以分号分隔的查询。只需确保您使用 CFQUERYPARAM 来筛选 SQL 注入(inject)攻击。
