querydsl withrecursive参数WITH RECURSIVE 是SQL 中用于执行递归查询的语法。它通常用于处理层次结构数据，例如树形结构或图形数据。WITH RECURSIVE 允许你定义一个递归的公共表表达式（CTE），并在查询中使用它。在 QueryDSL 中，WITH RECURSIVE 语法可以通过 querydsl-sql 模块进行支持。以下是一个简单的示例，演示如何在...
`withRecursive`方法的定义如下: ```java <S extends SimpleExpression<T>> WithBuilder<T> withRecursive(S alias); ``` 该方法参数`alias`是一个处理递归结果的表达式。在递归查询中,会使用到这个表达式,将递归结果与原始查询结果合并。 下面是一个示例,演示如何在QueryDSL中使用`withRecursive`方法实现递归查询...
