Description

MySQL Error 3708, "Missing mandatory attribute %s," indicates that a required parameter or property was not provided for a specific SQL statement, function call, or object definition. This error commonly occurs when working with features that enforce strict attribute requirements, such as Spatial Reference Systems (SRS) or complex data type definitions.

💬

Error Message

Missing mandatory attribute %s.

🔍

Known Causes

3 known causes

⚠️

Omitted Mandatory Parameter

A necessary parameter or attribute was simply left out of the SQL statement, function call, or object definition, preventing its successful execution.

⚠️

Incorrect Syntax or Typos

The SQL syntax used to specify the attribute is malformed, or there is a typographical error in the attribute's name, causing it to be unrecognized by MySQL.

⚠️

Missing SRID in Spatial Operations

When performing spatial operations or defining spatial objects, the mandatory Spatial Reference ID (SRID) attribute was not provided, which is crucial for geometric calculations.

Solutions

3 solutions available

1. Verify Stored Procedure/Function Syntax and Arguments easy

Ensure all required parameters are provided when calling or defining stored routines.

1

Identify the stored procedure or function that is causing the error. The error message 'Missing mandatory attribute %s' often indicates a missing parameter name or value in the call to the routine.

2

Review the definition of the stored procedure or function. Check if there are any parameters declared as mandatory (e.g., not nullable and without default values).

SHOW CREATE PROCEDURE your_procedure_name;
SHOW CREATE FUNCTION your_function_name;

3

If you are calling the routine, ensure you are passing values for all declared parameters, or that you are providing appropriate default values if they are optional.

CALL your_procedure_name(value1, value2, ...);
SELECT your_function_name(value1, value2, ...);

4

If the error message points to a specific attribute (e.g., 'parameter_name' or 'routine_type'), double-check that you have provided it correctly during the routine's creation or invocation.

2. Check for Incomplete DDL Statements medium

Correctly complete Data Definition Language (DDL) statements that might be missing essential components.

1

This error can occur during DDL operations like `CREATE TABLE`, `ALTER TABLE`, `CREATE INDEX`, etc., if a mandatory clause or attribute is omitted. Examine the DDL statement you are executing.

2

For example, when creating a table, ensure you define columns with appropriate data types and constraints if required. If you're adding a primary key, ensure the column(s) are specified.

CREATE TABLE example_table (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL
);

3

When altering a table, make sure you specify the action (e.g., `ADD COLUMN`, `MODIFY COLUMN`, `DROP COLUMN`) and the relevant column details.

ALTER TABLE example_table ADD COLUMN email VARCHAR(255);
ALTER TABLE example_table MODIFY COLUMN name VARCHAR(500) NOT NULL;

4

Consult the MySQL documentation for the specific DDL statement you are using to confirm all mandatory attributes are present and correctly formatted.

3. Examine MySQL Configuration and System Variables advanced

Investigate potential issues with MySQL server configuration or dynamic system variables.

1

In rare cases, this error might be related to internal MySQL server behavior or incorrect system variable settings. Review your `my.cnf` or `my.ini` configuration file for any unusual settings.

2

Check the values of relevant system variables that might influence routine creation or execution. For instance, `sql_mode` can impact how SQL statements are parsed and validated.

SHOW VARIABLES LIKE 'sql_mode%';

3

If you suspect a configuration issue, try reverting to default `sql_mode` settings or a known good configuration and restart the MySQL server.

SET GLOBAL sql_mode = 'STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION';
-- Then restart MySQL server

4

Consider consulting the MySQL error logs for more detailed information that might accompany error 3708.
