How to Fix MySQL Error 1124 – SQLSTATE: HY000 (ER_UDF_NO_PATHS) No paths allowed for shared library

MySQL is a popular open-source relational database management system used by many websites and applications. However, like any software, it can encounter errors that can disrupt its normal operation. One such error is MySQL Error 1124 – SQLSTATE: HY000 (ER_UDF_NO_PATHS) No paths allowed for shared library. In this article, we will explore what this error means and how to fix it.

Understanding MySQL Error 1124

MySQL Error 1124 occurs when you try to create or use a user-defined function (UDF) in MySQL, but the shared library file required for the UDF cannot be found. This error is specifically related to the absence of paths for shared libraries.

When you create a UDF in MySQL, you need to specify the shared library file that contains the implementation of the function. This file should be located in a directory that MySQL can access. If the shared library file is not found in any of the specified directories, MySQL throws Error 1124.

Fixing MySQL Error 1124

To fix MySQL Error 1124, you need to ensure that the shared library file for the UDF is located in a directory that MySQL can access. Here are the steps to follow:

Step 1: Locate the shared library file

First, you need to locate the shared library file for the UDF. This file should have a file extension like .so (on Linux) or .dll (on Windows). Make sure you have the correct file for the UDF you are trying to use.

Step 2: Determine the directories MySQL searches for shared libraries

MySQL searches for shared libraries in specific directories. To determine these directories, you can use the following command in the MySQL command-line client:

SHOW VARIABLES LIKE 'plugin_dir';

This command will display the directories where MySQL looks for shared libraries. Note down these directories for the next step.

Step 3: Move the shared library file to a directory MySQL can access

Now, move the shared library file to one of the directories you noted down in the previous step. Make sure the file has the necessary permissions for MySQL to access it.

Step 4: Restart MySQL

After moving the shared library file, you need to restart MySQL for the changes to take effect. You can do this by restarting the MySQL service or using the appropriate command for your operating system.

Step 5: Test the UDF

Once MySQL is restarted, you can test the UDF to see if the error is resolved. Try creating or using the UDF and check if it works without throwing Error 1124.

Conclusion

MySQL Error 1124 – SQLSTATE: HY000 (ER_UDF_NO_PATHS) No paths allowed for shared library can be fixed by ensuring that the shared library file for the UDF is located in a directory that MySQL can access. By following the steps outlined in this article, you can resolve this error and continue using user-defined functions in MySQL.
