MySQL Error 1860: Path Length Exceeded
Description
This error occurs when the combined length of a database name, table name, or other object identifier, along with the MySQL data directory path, exceeds the maximum path length allowed by the operating system or filesystem. It typically prevents MySQL from creating necessary files for the database or its objects.
Error Message
Long database name and identifier for object resulted in path length exceeding %d characters. Path: '%s'.
Known Causes
4 known causesExcessively Long Database Name
The database name itself is very long, contributing significantly to the overall file path length on the underlying filesystem.
Long Table or Object Identifier
A table, index, or other database object has an identifier that, when combined with the database name, creates an overly long path.
Deep MySQL Data Directory Path
The MySQL data directory (`datadir`) is located deep within the filesystem hierarchy, leaving less room for database and object names.
Operating System Path Length Limit
The underlying operating system (e.g., Windows) enforces a strict maximum path length that MySQL's file creation operations encounter.
