如果遇到

SELECT * FROM a AS a
LEFT JOIN b AS b ON a.bid=b.id
LEFT JOIN c AS c ON a.cid=c.id
LEFT JOIN d AS d ON a.did=d.id 
WHERE 1=1

这段Sql由于d表有多条关于a的数据时，会出现原本只有一条数据，变成多条数据，

这是因为在联b表时，没有加AND限制，可改写成：

SELECT * FROM a AS a
LEFT JOIN b AS b ON a.bid=b.id
LEFT JOIN c AS c ON a.cid=c.id
LEFT JOIN d AS d ON a.did=d.id AND te.vesting_date=(select max(vesting_date) from tbl_environment where sno=te.sno)
WHERE 1=1
