MySQL Error 1122: UDF Loading Failure
Description
This error indicates that MySQL attempted to load a User-Defined Function (UDF) but failed to find or access the associated shared library file. It typically occurs when the database server cannot locate the UDF's binary, has insufficient permissions to read it, or the UDF was not correctly registered.
Error Message
Can't load function '%s'
Known Causes
4 known causesMissing UDF Library File
The shared library file (.so on Linux, .dll on Windows) for the UDF is either missing from the expected MySQL plugin directory or its path is incorrect.
Incorrect File Permissions
The MySQL server process lacks the necessary read and execute permissions for the UDF's shared library file or the directory where it resides.
UDF Not Registered Correctly
The UDF was not properly registered with MySQL using the `CREATE FUNCTION` statement, or the `SONAME` (library name) specified during registration is incorrect.
Architecture Mismatch/Corruption
The UDF library file might be compiled for a different system architecture than the MySQL server, or the file itself is corrupted and unreadable.
