当我为ticket_no列运行此查询时，仅提取第一个数据。剩余的列正确获取。我正在尝试解决此错误超过2天。提前致谢

Answer 1

根据OP的评论（“对于每一行，ticket_no值相同”），问题是ticket_no字段的子查询不是相关的。这意味着它的值不依赖于外部查询中的任何值：

...
IFNULL(MAN_REQ.TICKET_NO,(select TICKET_NO from TC_FLIGHTS_BOOK tfb join TC_TRANSACTION tcx on(tcx.TRANSACTION_ID=tfb.TRANSACTION_ID) join TC_FB_FARE_DETAILS tf on (tf.OID=tfb.OID) limit  1))  AS "TICKET_NO",
...

这也意味着MAN_REQ.TICKET_NO字段始终为空，这就引出了为什么它首先存在的问题。

由于问题与数据有关，问题没有描述表格的相关性，也没有提供任何样本数据，我无法提供准确的解决方案，只能指出根本原因。

只从sql获取一个数据
