Sql 内部查询返回多行

上述查询未执行，因为

内部查询返回多行

单独运行以下子查询，查看哪个子查询返回多行，因为您可能需要使用DISTINCT（或Group By）或在where子句中添加另一个条件，使其唯一（取决于您的数据）。如果子查询返回多行，则不能作为完整查询运行

好的，很高兴知道。也许把它们改成相关查询。你可以在子查询中使用max（）和min（）函数。威尔只是说你可以单独检查每个子查询，并检查重复的内容。如果它们实际上是相同的，只是增加了一倍，您可以对它们使用

DISTINCT

。否则，您将需要一个聚合（如果可能的话）。您也可以加入表，改为修改语句以解决此问题。-在ANSI-92 SQL标准中（20多年前），旧样式的逗号分隔表列表样式被正确的ANSI

JOIN

语法所取代，不鼓励使用它

 (SELECT AI.AUTH_CODE FROM AUTHORIZATION_INFO AI WHERE AI.PAYMENT_TYPE_CD = op.PAYMENT_TYPE_CD AND AI.ORDER_KEY = op.ORDER_KEY AND AI.AUTH_TYPE_CD = 'PRE' ) 

 (SELECT AI.AUTH_STATUS_DESC FROM AUTHORIZATION_INFO AI WHERE AI.PAYMENT_TYPE_CD = op.PAYMENT_TYPE_CD AND AI.ORDER_KEY = op.ORDER_KEY AND AI.AUTH_TYPE_CD = 'PRE' ) 

 (SELECT UPDATED_DT FROM SETTLEMENT_REFUND_RESP WHERE TRANSACTION_TYPE_CODE = 'SET' AND PAYMENT_TYPE_CD ='DQP' AND ORDER_KEY = OP.ORDER_KEY ) REQUEST_DATE ,
