Please refer the following link for more information on Recursive Querying in SQL Server. https://technet.microsoft.com/en-us/library/ms186243(v=sql.105).aspx Using the above recursive query as a base, built a Stored Procedure that accepts ‘Bill Number’ as an input parameter and returns ...

在SQL Server 中,递归查询的使用 | 在 SQL Server 中,递归查询通常使用 Common Table Expressions (CTE)来实现。CTE 允许你定义一个临时的结果集,可以在查询中引用它。递归 CTE 是一种特殊的 CTE,它可以在其定义中引用自身,从而实现递归查询。 一、递归 CTE 的基本结构 递归CTE 由两部分组成: 1. 锚点成员(A...
This is the second article in the series of articles on Common Table Expression in Sql Server. Below are the other articles in this series: Introduction to Common Table Expression (a.k.a CTE) Multiple CTEs in a Single Query Nested Common Table Expressions Recursive Common Table Expression ...
This is very risky, but sometimes you may want to write a very deep recursion. In such queries, it is vital to include a termination check or youmay have to restart the whole database! Take a look at a query without any recursion depth limit and with a proper termination check: ...
FROM cte WHERE n < 50 -- terminator ) SELECT n FROM cte; Here are the results: Conclusion Common table expressions come in handy when you need to simplify a query. Though some would contend that using recursive CTEs doesn’t lend to this goal, as they can be conceptually difficult to ...
A recursive CTE can greatly simplify the code required to run a recursive query within a SELECT, INSERT, UPDATE, DELETE, or CREATE VIEW statement. In earlier versions of SQL Server, a recursive query usually requires using temporary tables, cursors, and logic to control the flow of the recurs...

My example solution uses the column "Path" to find all parts used by all subassemplies, including all subassemplies used by those subassemblies without using a recursive function. Recursion is definitely feasible, (I saw you used it already yourself), but in general Power Query does not ...
Recursive CTEs always follow the same pattern. The body of the CTE is a UNION ALL query that combines one or more anchor sub-selects which seed the result set and one or more recursive sub-selects which generate the remainder of the result set. The recursive sub-selects reference the rec...
