MySQL Error 3581: Window Partitioning Dependency
Description
This error occurs when MySQL detects an attempt to define partitioning on a window function that is derived from or explicitly depends on another window function. MySQL's architecture prevents partitioning from being directly applied to such dependent window contexts, indicating an invalid or unsupported query structure. It typically appears in complex analytical queries.
Error Message
A window which depends on another cannot define partitioning.
Known Causes
3 known causesNested Window Partitioning
Attempting to apply a `PARTITION BY` clause within a window function that operates on the result set of another, already defined, window function.
Partitioning Derived Window Output
Trying to define partitioning on a result set that has already been processed by a window function and is implicitly treated as a dependent window.
Incorrect Query Structure
Building a SQL query where the logical flow incorrectly implies partitioning a window function that relies on another window's output.
