java - 常量解释为 QueryDSL 中的表达式

Question

我有以下查询:

DateExpression<Date> endDatePlus7 = DateTemplate.create(Date.class, "DATE_ADD({0},INTERVAL {1} day)", buy.endDate, Expressions.constant(7));

BooleanExpression exp = ad.brandSurveyType.ne(BrandSurveyType.NONE).and((buy.status.eq(NewBuyStatus.CLOSED).and(buy.endDate.after(endDatePlus7))).not());

query.where(exp);

当查看生成的查询字符串时，queryDSL 将“7”常量解释为要计算的另一个表达式，并产生以下错误:

line 4:113: unexpected token: ?

我使用的是queryDSL 2.9

Answer 1

在您的示例中，您将 7 视为模板的参数

DateExpression<Date> endDatePlus7 = DateTemplate.create(Date.class, 
    "DATE_ADD({0}, INTERVAL {1} day)", buy.endDate, Expressions.constant(7));

如果您想将 7 直接序列化到您的 JPQL 代码片段，请像这样编写

DateExpression<Date> endDatePlus7 = DateTemplate.create(Date.class,
    "DATE_ADD({0}, INTERVAL {1s} day)", buy.endDate, Expressions.constant(7));

由于Querydsl 3.0常量会自动换行，所以就变成了

DateExpression<Date> endDatePlus7 = DateTemplate.create(Date.class,
    "DATE_ADD({0}, INTERVAL {1s} day)", buy.endDate, 7);
