Description

MariaDB Error 1108 indicates that a stored procedure was called with arguments that do not match its definition. This typically occurs when there's a mismatch in the number, data types, or order of parameters provided during the procedure call.

💬

Error Message

Incorrect parameters to procedure '%s'

🔍

Known Causes

4 known causes

⚠️

Argument Count Mismatch

The number of arguments provided in the procedure call does not match the number expected by the stored procedure's definition.

⚠️

Data Type Incompatibility

One or more arguments passed to the procedure have data types that are incompatible with the corresponding parameters defined in the procedure signature.

⚠️

Incorrect Argument Order

Arguments are passed in an order that does not align with the sequence of parameters defined in the stored procedure.

⚠️

Stale Procedure Definition

The stored procedure's definition has been altered, but the calling code or application has not been updated to reflect these changes.

Solutions

3 solutions available

1. Verify Procedure Parameter Count and Order easy

Ensure the number and order of arguments passed to the stored procedure match its definition.

1

Identify the stored procedure that is causing the error. The error message '%s' will typically contain the name of the procedure.

2

Retrieve the definition of the stored procedure to check its expected parameters.

SHOW CREATE PROCEDURE procedure_name;
-- Or for older versions:
DESCRIBE procedure_name;

3

Compare the parameters you are passing in your call to the procedure with the parameters defined in its `CREATE PROCEDURE` statement. Pay close attention to the number of parameters, their data types, and their order.

4

Correct your procedure call to match the expected parameter signature.

CALL procedure_name(value1, value2, ...);

2. Check Data Type Compatibility of Arguments medium

Confirm that the data types of the values passed to the procedure are compatible with the defined parameter types.

1

Obtain the stored procedure's definition using `SHOW CREATE PROCEDURE procedure_name;` or `DESCRIBE procedure_name;`.

SHOW CREATE PROCEDURE procedure_name;

2

Examine the data types of each parameter in the procedure definition.

3

Review the data types of the values you are passing to the procedure. If a value's data type is not directly compatible, consider explicit casting or ensuring the value is correctly formatted.

SELECT CAST(your_variable AS expected_data_type);

4

Adjust the data types or format of the arguments in your procedure call to match the expected types.

CALL procedure_name(CAST(value1 AS INT), value2, ...);

3. Inspect Procedure Invocation Context medium

Ensure the context from which the procedure is called provides the correct parameters, especially when called from other procedures or functions.

1

If the procedure is called from within another stored procedure, function, or trigger, examine the calling code. Use `SHOW CREATE PROCEDURE calling_procedure_name;` to see how it invokes the problematic procedure.

SHOW CREATE PROCEDURE calling_procedure_name;

2

Trace the values of the variables or expressions being passed as arguments. Ensure they are correctly populated and have the expected values before the call.

3

Verify that any intermediate calculations or data transformations within the calling code are producing valid inputs for the called procedure.

4

If necessary, add logging or debugging statements within the calling code to inspect parameter values just before the procedure call.

SELECT CONCAT('Calling procedure with param1: ', param1_variable, ', param2: ', param2_variable) AS debug_message;
