Sql Server Recursive Sql Command And Duplicate Results Stack Overflow

Sql Server Recursive Sql Command And Duplicate Results Stack Overflow I was wondering if how i am handling removing duplicate results using distinct is the best way to approach my recursive call. here is my code sample: with cte as ( select dbo.users.username, dbo.co. Instead of using a recursive cte, you could consider using the built in hierarchyid sql server type to store the hierarchy. i've put together a short mcve to illustrate how this works.

Sql Server Recursive Sql Command And Duplicate Results Stack Overflow In this article, we are going to learn about the implementation of recursive cte in sql servers. we will understand how recursive common table expressions work step by step and understand their workflow through various examples. Summary: in this tutorial, you will learn how to use the sql server recursive cte to query hierarchical data. a recursive common table expression (cte) is a cte that references itself. by doing so, the cte repeatedly executes, returns subsets of data, until it returns the complete result set. You don't need recursion to find previous rows in a set, that's what the over(partition by order by ) clause is for. you can use that with aggregation functions like sum, count etc. We need a better way to implement recursive queries in sql server and in this article we look at how this can be done using a common table expression or cte.

I wrote a cte to recursively follow foreign key references to a given base table, but ran into infinite loops in multiple places. i like the idea of keeping a path element to allow cutting off those loops. For duplicates you can apply group by sourcepeopleid,targetpeopleid to table people, leaving only one connection (any), before recursion. to avoid cycles common way is collect path of traversed rows. Recursive queries are useful when building hierarchies, traverse datasets and generate arbitrary rowsets etc. the recursive part (simply) means joining a rowset with itself an arbitrary number of times. When running this, i'm getting over 200 rows of duplicated data, instead of a single line that includes the results i'm looking for. does anyone have any suggestions on how to get this working?.
