带有 "in" 查询的 GORM where 闭包删除生成的 SQL 中的 where 子句

Question

源代码： https://github.com/HybridProgrammer/GormIn

Grails 版本：3.2.8

我正在尝试 运行 以下查询：

def query = UserData.where {
    teams { id in teamIds }
}

当 运行在 Spock 测试中查询时，它工作正常。当从 Grails 服务中 运行 连接它时，它 returns UserData 中的所有行，并且不会仅过滤掉属于 teamIds 列表中的团队的那些用户。

Spock 测试

运行 来自 Spock 测试的查询 - 始终通过

void "never fails - direct approach"() {
    given:
    setupData()
    def me = User.first()
    def teamIds = me.getAuthorities().id

    when:
    def query = UserData.where {
        teams { id in teamIds }
    }

    then:
    teamIds.size() == 1
    query.size() == 2
}

生成SQL

select count(*) as y0_ 
from user_data this_ inner join workflow_role_teams teams3_ 
    on this_.id=teams3_.user_data_teams_id inner join role teams_alia1_ 
    on teams3_.role_id=teams_alia1_.id 
 where teams_alia1_.id in (?) 
 limit ?

运行 来自 Grails 服务的查询

偶尔通过 IntelliJ，从不形成 CLI

void "sometimes fails"() {
    given:
    setupData()
    def me = User.first()

    when:
    def query = exampleService.getMyOrMyTeamsData(me)

    then:
    me.getAuthorities().size() == 1
    query.size() == 2
}

exampleService.getMyOrMyTeamsData

def getMyOrMyTeamsData(User me) {
    def teamIds = me.getAuthorities().id

    def query = UserData.where {
        teams { id in teamIds }
    }

    return query
}

生成SQL

select count(*) as y0_ 
from user_data this_ inner join workflow_role_teams teams3_ 
    on this_.id=teams3_.user_data_teams_id inner join role teams_alia1_ 
    on teams3_.role_id=teams_alia1_.id 
limit ?

Answer 1

这里回答了问题：

在grails-app/domain/oneisone/UserData.groovy

List teams = new ArrayList()

改为

List<Role> teams = new ArrayList()

运行 grails clean 然后重新运行测试。
