使用Grails3.3.8和MySQLDB5.5.x版本。我已完成此查询:
String query = $/
select new Map( i1.id as id,i1.name as name)
from CustomerComposition as c1
inner join c1.instrument as i1
left join i1.analisys as a1,
Instrument as i2
left join i2.analisys as a2,
Instrument as i3
left join i3.analisys as a3
where
i1.id=i2.id and i1.id=i3.id and
c1.portfolio.id=:ptfId and a1.phase.id=:p1Id and a2.phase.id=:p2Id and a3.phase.id=:p3Id
/$
List composition = CustomerComposition.executeQuery(query,
[ptfId: ptfId, p1Id: phase[0], p2Id: phase[1], p3Id: phase[2]])
左连接不起作用。然后我意识到它不起作用,因为我在where中加了一个子句。我用简单的sql语句进行了双重检查,事实上,只要将条件移到where,它就可以工作了。一个简单的剪贴只是为了澄清,之前,它没有工作:
SELECT
instrument1_.id
FROM
customer_ptf_composition customerpt0_
INNER JOIN instrument instrument1_ ON customerpt0_.instrument_id = instrument1_.id
LEFT JOIN analisys analisys4_ ON instrument1_.id = analisys4_.instrument_id
WHERE
customerpt0_.portfolio_id =1216
AND analisys4_.phase_id =111
在和之后,由于左/右连接的工作方式,它可以工作:
SELECT
instrument1_.id
FROM
customer_ptf_composition customerpt0_
INNER JOIN instrument instrument1_ ON customerpt0_.instrument_id = instrument1_.id
LEFT JOIN analisys analisys4_ ON instrument1_.id = analisys4_.instrument_id AND analisys4_.phase_id =111
WHERE
customerpt0_.portfolio_id =1216
现在我的问题是如何在gorm中把“and field=value”放在左连接旁边?

可以使用with子句实现以下目的:
