    }
]

对应后端输出sql:

... WHERE  ( (  SY_CREATETIME is null ) )

inSelect inSelect

查询 DEVELOPLOG_ACT_CODE 数据在 ( DICTIONARYITEM_ITEMCODE字段值 JE_CORE_DICTIONARYITEM 表 DICTIONARYITEM_DICTIONARY_ID 为 ZQnboCooVszhRVXj2Si 的数据)

j_query信息:

[
    {
        "type": "inSelect",
        "code": "DEVELOPLOG_ACT_CODE",
        "value": {
            "table": "JE_CORE_DICTIONARYITEM",
            "code": "DICTIONARYITEM_ITEMCODE",
            "conditions": [{
                "type": "=",
                "code": "DICTIONARYITEM_DICTIONARY_ID",
                "value": "ZQnboCooVszhRVXj2Si",

            }]
        },
        "cn": "and"
    }
]

对应后端输出sql:

... WHERE  (  DEVELOPLOG_ACT_CODE IN (SELECT DICTIONARYITEM_ITEMCODE FROM JE_CORE_DICTIONARYITEM WHERE  DICTIONARYITEM_DICTIONARY_ID = 'ZQnboCooVszhRVXj2Si' )  )
