oracle sql multi-table query

2022-08-04 08:34:00 【CSDN Q&A】

What's wrong with my sql? The multi-table query condition is that the APPLY_NO of table 1 is equal to the APPLY_NO of table 2, and then I get some data 

 SELECT APPLY_NO FROM T_APPLY_INFO T1 LEFT JOIN T_SDS_UPD_APPLY_INFO T2 ON T1.APPLY_NO = T2.APPLY_NOWHERE APPLY_NO = :applyNo
