MySQL Error 3577: Recursive CTE Single Reference Violation
Description
This error occurs when defining a recursive Common Table Expression (CTE) in MySQL. It specifically indicates a violation in the recursive query block where the recursive table is either referenced more than once or is referenced within a subquery, both of which are disallowed.
Error Message
In recursive query block of Recursive Common Table Expression '%s', the recursive table must be referenced only once, and not in any subquery
Known Causes
3 known causesMultiple Recursive Table References
The recursive part of your CTE (after the UNION ALL) contains more than one reference to the recursive table's own name.
Recursive Table in Subquery
The recursive member of your CTE references the recursive table within a subquery, which is explicitly forbidden.
Improper Recursive CTE Structure
The overall design of your recursive CTE's `UNION ALL` query does not align with MySQL's specific syntax rules for recursive queries, leading to these reference issues.
