Description

This warning indicates that a specific SQL syntax or feature used in your query is considered outdated and will be removed in a future MariaDB version. It prompts users to update their code to use the recommended alternative syntax before the deprecated feature is no longer supported. This error typically occurs when executing SQL statements developed for older database versions or when using features that have been superseded.

💬

Error Message

The syntax '%s' is deprecated and will be removed in MariaDB %s. Please use %s instead

Known Causes

3 known causes

⚠️

Legacy Application Code

Executing SQL queries or scripts from older applications that have not been updated to use current MariaDB syntax standards.

⚠️

Database Version Upgrade

Migrating to a newer MariaDB version where previously valid SQL syntax has been marked as deprecated.

⚠️

Outdated Development Practices

Writing new SQL code that inadvertently uses deprecated syntax due to lack of awareness of current best practices or official documentation.

Solutions

3 solutions available

1. Update SQL Queries for Deprecated Syntax medium

Identify and replace the deprecated syntax in your SQL queries.

1

Examine the error message carefully to identify the specific deprecated syntax (`%s`) and the recommended replacement (`%s`).

Example: ERROR 1554: Deprecated SQL Syntax Usage: The syntax 'LIMIT 0, 10' is deprecated and will be removed in MariaDB 11.0. Please use 'LIMIT 10 OFFSET 0' instead.

2

Locate all instances of the deprecated syntax in your application's SQL queries, stored procedures, or views.

You might need to search your codebase, database scripts, and potentially use `SHOW CREATE PROCEDURE` or `SHOW CREATE VIEW` commands.

3

Replace the deprecated syntax with the recommended alternative. For the 'LIMIT offset, count' syntax, change it to 'LIMIT count OFFSET offset'.

UPDATE your_table SET column = 'new_value' WHERE id = 1;
-- Deprecated:
-- SELECT * FROM users LIMIT 0, 10;
-- Recommended:
SELECT * FROM users LIMIT 10 OFFSET 0;

4

Test your application thoroughly after making these changes to ensure functionality remains as expected and no new errors are introduced.

2. Leverage `information_schema` to Find Deprecated Syntax advanced

Query `information_schema` to identify stored routines and views using deprecated syntax.

1

Connect to your MariaDB server and execute a query against `information_schema.ROUTINES` to find stored procedures and functions that might contain deprecated syntax.

SELECT SPECIFIC_NAME, ROUTINE_DEFINITION FROM information_schema.ROUTINES WHERE ROUTINE_DEFINITION LIKE '%LIMIT 0,%'; -- Example for LIMIT offset,count

2

Query `information_schema.VIEWS` to find views that might contain deprecated syntax.

SELECT TABLE_NAME, VIEW_DEFINITION FROM information_schema.VIEWS WHERE VIEW_DEFINITION LIKE '%LIMIT 0,%'; -- Example for LIMIT offset,count

3

For each identified routine or view, retrieve its full definition using `SHOW CREATE PROCEDURE`, `SHOW CREATE FUNCTION`, or `SHOW CREATE VIEW`.

SHOW CREATE PROCEDURE your_procedure_name;
SHOW CREATE VIEW your_view_name;

4

Analyze the definitions for the specific deprecated syntax mentioned in the error message and update them accordingly, then re-create the routines/views.

DROP PROCEDURE IF EXISTS your_procedure_name;
DELIMITER //
CREATE PROCEDURE your_procedure_name() BEGIN
  -- Updated syntax here
END //
DELIMITER ;

DROP VIEW IF EXISTS your_view_name;
CREATE VIEW your_view_name AS
  -- Updated syntax here
;

3. Temporarily Suppress Deprecation Warnings (Not Recommended for Production) easy

Disable deprecation warnings for immediate relief, but plan for proper fixes.

1

Understand that this is a temporary workaround and does not resolve the underlying issue. It's highly recommended to address the deprecated syntax as soon as possible.

2

You can try to adjust the `sql_mode` server variable. However, directly suppressing deprecation warnings through `sql_mode` is not a standard or recommended practice in MariaDB. Deprecation warnings are typically informational and not controlled by `sql_mode` in the same way as syntax errors.

This approach is generally not feasible for suppressing deprecation warnings specifically. `sql_mode` is more for enforcing SQL standards and preventing invalid syntax.

3

The most effective way to 'suppress' these warnings is to fix the code that generates them. If this is an issue during development or testing, you might consider reviewing the specific SQL statements being executed and updating them.
