我正在使用queryDsl进行查询。
我使用它来创建BooleanExpresion。
我使用它来创建BooleanExpresion。
public BooleanBuilder getPredicate(BooleanBuilder pBuilderBusquePerso){
int dias = 30;
QEntity1 qEntity = QEntity1.entity;
pBuilderBusquePerso = pBuilderBusquePerso.and(qEntity.date1 != null
? (SQLExpressions.datediff(DatePart.day, qEntity.date2, qEntity.date1).lt(dias) ) :null );
return pBuilderBusquePerso;
}
在另一个过程中,我将其称为并执行如下:
BooleanBuilder pBuilderBusquePerso = new BooleanBuilder();
Predicate filter =getPredicate(pBuilderBusquePerso);
Page<Entity> iLista = myRepository.findAll(getMyPredicate(usr, filter, tipoListado, null, estados), paginacion);
所以 SQL 查询的结果是:
select table1 ta1
......
exists (
select 1
from
table2 ta2
where
ta1.inv_id=ta2.inv_id
and diff_days(ta1.inv_exp_date, ta2.exp_date)<?
)
出现以下错误:
Caused by: java.sql.SQLException: ORA-00904: "DIFF_DAYS": invalid identifier
因此,针对Oracle数据库的querysql翻译是错误的。是否有一种方法可以将queryDsl翻译成Oracle函数?我需要什么?
我也尝试过使用DATETRUNC。
pBuilderBusquePerso = pBuilderBusquePerso.and(qEntity.date1 != null
? (SQLExpressions.datetrunc(DatePart.day, qEntity.date1).castToNum(Integer.class).subtract(SQLExpressions.datetrunc(DatePart.day, qEntity.date2).castToNum(Integer.class))).lt(dias) :null );
exists (
select 1
from
table2 ta2
where
ta1.inv_id=ta2.inv_id
and cast(trunc_day(ta2.exp_date) as number(10,0))-cast(trunc_day(ta1.inv_exp_date) as number(10,0))<?
出现类似的错误:
原因:java.sql.SQLException: ORA-00904: "TRUNC_DAY": 无效标识符
并且添加天数
pBuilderBusquePerso = pBuilderBusquePerso.and(qEntity.date1 != null
? ((SQLExpressions.addDays(qEntity.date2, dias)).after(qEntity.date1)):null );
exists (
select 1
from
table2 ta2
where
ta1.inv_id=ta2.inv_id
and add_days(ta1.inv_exp_date, ?)>ta1.exp_date
)
出现了另一个类似的错误:
Caused by: java.sql.SQLException: ORA-00904: "ADD_DAYS": 无效标识符
我试图按照这个测试构建我的查询: https://searchcode.com/codesearch/view/17765673/
提前感谢。
编辑:这是完整的错误追踪。
