MariaDB Error 1681: Using Deprecated Syntax
Description
Error 1681 signifies that a specific SQL syntax, function, or feature you are using is deprecated in your current MariaDB version. While it might still function, it is scheduled for removal in an upcoming release, indicating a future compatibility issue.
Error Message
'%s' is deprecated and will be removed in a future release.
Known Causes
4 known causesOutdated SQL Syntax
Your queries or DDL statements utilize SQL syntax or features that have been marked as deprecated in recent MariaDB versions.
Database Upgrade
After upgrading MariaDB, existing applications or scripts may still use features that were deprecated in the new version.
Third-Party Tools
An application, ORM, or database management tool might be generating SQL statements that include deprecated elements.
Referencing Old Documentation
Code or configuration based on older MariaDB documentation or tutorials may inadvertently use deprecated features.
Solutions
3 solutions available1. Update Queries to Modern Syntax medium
Identify and replace deprecated SQL syntax in your queries.
1
Identify the specific deprecated syntax. The error message '%s' will usually tell you what is deprecated. Common examples include certain date/time functions or old `SELECT ... INTO` syntax.
Example: If the error is about 'SELECT ... INTO OUTFILE', consider using `LOAD DATA INFILE` for importing or `SELECT ... INTO OUTFILE` with a different approach if writing to a file is still required, though the direct deprecation usually refers to specific contexts.2
Consult the MariaDB documentation for the specific deprecated feature. Search for the feature name and 'deprecated' or 'removed' to find the recommended modern alternative.
Example: Search 'MariaDB SELECT INTO OUTFILE deprecated' or 'MariaDB date functions deprecated'.3
Rewrite your SQL queries to use the recommended syntax. This might involve changing function names, restructuring clauses, or using different statements entirely.
For example, if you were using a deprecated date function, replace it with its modern equivalent. If the deprecation is related to `SELECT ... INTO OUTFILE` for writing, you might need to re-evaluate the use case or use alternative methods for file generation.4
Test your updated queries thoroughly to ensure they function as expected and do not introduce new issues.
2. Review Stored Procedures and Functions medium
Check and update any stored routines that use deprecated syntax.
1
List all stored procedures and functions in your database.
SHOW PROCEDURE STATUS WHERE Db = 'your_database_name';
SHOW FUNCTION STATUS WHERE Db = 'your_database_name';2
For each routine, retrieve its definition.
SHOW CREATE PROCEDURE your_procedure_name;
SHOW CREATE FUNCTION your_function_name;3
Examine the definition for any deprecated syntax identified in the error message.
4
Modify the routine's definition to use the current, supported syntax.
DROP PROCEDURE your_procedure_name;
DROP FUNCTION your_function_name;
-- Re-create with updated syntax5
Re-create the stored procedure or function with the corrected syntax.
DELIMITER $$
CREATE PROCEDURE your_procedure_name(...)
BEGIN
-- Updated SQL statements
END$$
DELIMITER ;6
Test the updated routines by calling them.
CALL your_procedure_name(...);3. Update Client Applications and Connectors easy
Ensure your application code and database connectors are up-to-date.
1
Check the version of your MariaDB client libraries or database connectors (e.g., PHP PDO, Python MySQL Connector, Java Connector/J).
2
Consult the documentation for your specific connector or library. Older versions might generate queries that use deprecated syntax, or the connector itself might have compatibility issues with newer MariaDB features/syntax.
3
Update your client application's dependencies to the latest stable version of the MariaDB connector or library.
Example (Python with pip):
pip install --upgrade mariadb4
Rebuild and redeploy your application.
