Description

Error 1281, ERR_SQLSCRIPT_WRONG_PARAMS, indicates that a SQLScript function or procedure was called with an incorrect number of arguments or arguments of incompatible data types. This error typically occurs during the execution of custom SQLScript logic within the SAP HANA database layer, which underpins SAP S/4HANA operations.

Error Message

ERR_SQLSCRIPT_WRONG_PARAMS

🔍

Known Causes

4 known causes

⚠️

Mismatched Parameter Count

The number of arguments provided in the function or procedure call does not match the expected number of parameters defined in its signature.

⚠️

Incompatible Data Types

One or more arguments passed to the function or procedure have a data type that is incompatible with the corresponding parameter's defined type.

⚠️

Incorrect Parameter Order

When calling a function or procedure without named parameters, the positional order of the supplied arguments does not match the defined order of parameters.

⚠️

Outdated Function Signature

The called function or procedure's definition has changed (e.g., parameters added or removed), but the calling code has not been updated.

Solutions

3 solutions available

1. Verify Stored Procedure/Function Signature and Call easy

Ensure the parameters passed to the SQLScript match its defined signature.

1

Identify the SQLScript (stored procedure or function) causing the error. This information is usually available in the application logs or the error message itself.

2

Retrieve the definition of the SQLScript. You can do this using SQL Developer, HANA Studio, or by querying the system catalog.

SELECT * FROM SYS. PROCEDURES WHERE PROCEDURE_NAME = '<YOUR_PROCEDURE_NAME>';
SELECT * FROM SYS.FUNCTIONS WHERE FUNCTION_NAME = '<YOUR_FUNCTION_NAME>';

3

Carefully compare the number, data types, and order of parameters in the SQLScript definition with the parameters being passed during the call.

4

Correct any discrepancies in the calling code to align with the SQLScript's signature.

Example: If the procedure expects an INTEGER and a VARCHAR, ensure your call provides them in that order and type.
CALL "MY_SCHEMA"."MY_PROCEDURE"(123, 'some_value');

2. Check Data Type Mismatches medium

Address situations where parameter data types are incompatible.

1

As in the previous solution, identify the SQLScript and retrieve its definition.

2

Pay close attention to the data types of each parameter in the SQLScript definition (e.g., VARCHAR, INTEGER, DECIMAL, TIMESTAMP, TABLE type).

3

Examine the data types of the variables or literals being passed from the calling application or another SQLScript.

4

If a mismatch is found, explicitly cast the parameter in the calling code to the expected data type of the SQLScript. HANA SQLScript supports various casting functions.

Example: If the SQLScript expects a DECIMAL and you are passing a VARCHAR, cast it:
CALL "MY_SCHEMA"."MY_PROCEDURE"(CAST('123.45' AS DECIMAL(10,2)));

Or if passing a date as a string:
CALL "MY_SCHEMA"."MY_PROCEDURE"(TO_DATE('2023-10-27', 'YYYY-MM-DD'));

5

For table type parameters, ensure the structure (column names and data types) of the table being passed exactly matches the table type definition in the SQLScript.

3. Validate Table Type Parameters medium

Ensure table type parameters are correctly structured and populated.

1

Locate the SQLScript that uses a table type parameter and retrieve its definition.

SELECT * FROM SYS.FUNCTIONS WHERE FUNCTION_NAME = '<YOUR_FUNCTION_WITH_TABLE_PARAM>';
SELECT * FROM SYS.PROCEDURES WHERE PROCEDURE_NAME = '<YOUR_PROCEDURE_WITH_TABLE_PARAM>';

2

Examine the `PARAMETER_TYPE` and `PARAMETER_DATA_TYPE` columns in the system catalog views for the table type parameter. This will show the name of the table type.

3

Retrieve the definition of the table type itself.

SELECT * FROM SYS.TABLE_TYPES WHERE TABLE_TYPE_NAME = '<THE_TABLE_TYPE_NAME>';

4

In the calling code, ensure the table variable being passed has columns that precisely match the names and data types defined in the table type.

Example: If the table type is defined as `MY_TABLE_TYPE AS TABLE (ID INT, NAME VARCHAR(50))`, your calling table variable must have these exact columns.

5

If populating the table variable programmatically, ensure that data is inserted into the correct columns and that the data types are compatible.

Example (within another SQLScript or application logic):
DECLARE my_data MY_TABLE_TYPE;
INSERT INTO :my_data VALUES (1, 'Item A');
INSERT INTO :my_data VALUES (2, 'Item B');
CALL "MY_SCHEMA"."MY_PROCEDURE_WITH_TABLE_PARAM"(:my_data);
