Description

Error 1339, ERR_SQLSCRIPT_TOO_MANY_PARAMS, indicates that an SAP HANA SQLScript function, procedure, or statement has been invoked or defined with a number of parameters exceeding the system's allowed limit. This typically occurs during the execution or compilation of SQLScript code within SAP S/4HANA when parameter counts are exceptionally high.

Known Causes

3 known causes

⚠️

Exceeding SQLScript Parameter Limit

A function or procedure within SAP HANA SQLScript has been defined or called with more parameters than the internal system limit (e.g., 1024 parameters) allows for a single object.

⚠️

Overly Complex Dynamic SQL Generation

Dynamic SQL or prepared statements generated by an application or custom logic might inadvertently create a query with an excessive number of placeholder parameters, leading to this error during execution.

⚠️

Automated Code Generation Issues

Tools or custom scripts that automatically generate SQLScript code may produce procedures or functions with an unintended and unmanageable number of input or output parameters.

Solutions

3 solutions available

1. Refactor Stored Procedure/Function to Reduce Parameters advanced

Restructure the SQLScript to use fewer input and output parameters.

1

Analyze the existing SQLScript that is causing the error. Identify all input and output parameters.

SELECT * FROM SYS.PROCEDURES WHERE PROCEDURE_NAME = 'YOUR_PROCEDURE_NAME';

2

Group related parameters into structures or table types if possible. This is a common approach in SAP HANA to bundle data.

CREATE TYPE "MY_SCHEMA"."MY_PARAM_STRUCT" AS OBJECT (
  param1 INT,
  param2 VARCHAR(100)
);

-- Then modify the procedure to accept a single parameter of this type.

3

Alternatively, consider passing a table type as a single parameter if you are dealing with a collection of data that was previously passed as individual parameters.

CREATE TYPE "MY_SCHEMA"."MY_TABLE_TYPE" AS TABLE (
  column1 INT,
  column2 VARCHAR(50)
);

-- Modify the procedure signature to accept a parameter of this table type.

4

Rewrite the SQLScript logic to accommodate the new parameter structure. This might involve iterating through the structure or table type.

-- Example of processing a table type parameter:
FOR lv_row AS SELECT * FROM :input_table_param DO
  -- Process lv_row.column1, lv_row.column2
END FOR;

5

Re-create or alter the stored procedure/function with the reduced parameter set.

ALTER PROCEDURE "MY_SCHEMA"."YOUR_PROCEDURE_NAME" (...) -- New parameter list
LANGUAGE SQLSCRIPT
AS
BEGIN
  -- New procedure body
END;

2. Leverage Temporary Tables for Intermediate Data medium

Use temporary tables to pass intermediate results instead of numerous output parameters.

1

Identify parameters that are primarily used to return intermediate calculation results or lists of data.

SELECT * FROM SYS.PROCEDURE_PARAMETERS WHERE PROCEDURE_NAME = 'YOUR_PROCEDURE_NAME';

2

Within the SQLScript, create a temporary table to store these intermediate results.

CREATE LOCAL TEMPORARY TABLE "#TEMP_RESULTS" (
  result_col1 INT,
  result_col2 VARCHAR(50)
);
-- Populate the temporary table with the required data.

3

Remove the corresponding output parameters from the stored procedure signature.

ALTER PROCEDURE "MY_SCHEMA"."YOUR_PROCEDURE_NAME" (...) -- Remove output parameters
LANGUAGE SQLSCRIPT
AS
BEGIN
  -- Procedure body including CREATE LOCAL TEMPORARY TABLE and population
END;

4

Ensure that the calling application or subsequent SQL statements know to access the temporary table (if it's a persistent temporary table, which is less common in this scenario, or if the procedure returns the name of the temp table). For a local temporary table, the caller needs to be aware of its existence or the procedure needs to return a way to access it.

SELECT * FROM "#TEMP_RESULTS"; -- In a subsequent statement within the same session

3. Adjust Parameter Binding in Calling Application medium

Modify how the parameters are passed from the application layer to the SQLScript.

1

Determine the programming language and framework used by your SAP S/4HANA application or custom code that calls the SQLScript (e.g., ABAP, Java, Node.js).

text: Identify the CALL statement or equivalent in your application code.

2

Review how parameters are being bound. If you are explicitly binding each parameter individually, and the number exceeds the HANA limit, you might be encountering issues.

text: Example in ABAP (conceptual):
CALL METHOD lo_statement->bind_parameter
  EXPORTING
    i_name  = 'PARAM1'
    i_value = lv_value1.

CALL METHOD lo_statement->bind_parameter
  EXPORTING
    i_name  = 'PARAM2'
    i_value = lv_value2. ... (many times)

3

If the calling framework supports it, consider using a mechanism to pass a structure or a map of parameters, which can then be mapped internally by the application before calling the SQLScript.

text: Example in Java using JDBC (conceptual):
PreparedStatement pstmt = connection.prepareStatement("CALL MY_SCHEMA.MY_PROCEDURE(?, ?, ...)");

// If possible, group parameters logically in Java objects before binding.

4

Ensure that you are not accidentally passing NULL values for parameters that are not intended to be optional or are causing unexpected parameter counts.

text: Check for explicit NULL assignments or uninitialized variables being passed.
