SAP S/4HANA Error 1315: SQLScript Result Set Conflict
Description
This error indicates a conflict in how an SAP HANA SQLScript procedure or function is attempting to return data. It occurs when a procedure's definition includes both a direct `SELECT` statement to return a result set and an explicit `RESULT VIEW` clause, which are mutually exclusive methods for outputting results.
Error Message
ERR_SQLSCRIPT_RETURN_RESULT_SET_WITH_RESULTVIEW: Return result set from SELECT statement exist when result view is defined
Known Causes
3 known causesDual Result Output Definition
The SQLScript procedure or function is defined with both a `RETURNS TABLE` or implicit `SELECT` statement for result output and an explicit `RESULT VIEW` definition, creating an ambiguity for the HANA engine.
Incorrect Procedure Syntax
The syntax used for the SQLScript procedure or function incorrectly combines elements meant for different result handling paradigms, such as a final `SELECT` statement alongside a `RESULT VIEW` clause.
Legacy Code or Migration Oversight
This can arise when migrating older SQLScript or refactoring existing code where a `RESULT VIEW` was added without removing a previously defined direct result set return mechanism.
Solutions
3 solutions available1. Remove SELECT Statement from Function/Procedure with Result View easy
Eliminate any explicit SELECT statements that return a result set within the SQLScript object that also defines a result view.
1
Identify the SQLScript object (e.g., stored procedure, user-defined function) that is causing the error. This is typically indicated in the surrounding error messages or logs.
2
Open the identified SQLScript object in your SAP HANA development environment (e.g., SAP Business Application Studio, SAP HANA Studio).
3
Locate any `SELECT` statements that are directly returning a result set (i.e., not part of a `CALL` or `INSERT INTO` statement).
SELECT column1, column2 FROM my_table;4
Remove or comment out these `SELECT` statements. The result view definition itself will provide the output for the SQLScript object.
-- SELECT column1, column2 FROM my_table;5
Save and activate the modified SQLScript object.
2. Modify Result View Definition to Incorporate Data medium
Adjust the result view definition to include the data that was previously intended to be returned by a SELECT statement.
1
Identify the SQLScript object and its associated result view definition. The error message should point to the specific object.
2
Examine the `SELECT` statement that is causing the conflict. Understand what data it is intended to return.
SELECT column1, column2 FROM my_table WHERE condition;3
Modify the `RESULT VIEW` clause of the SQLScript object to include the columns and logic from the conflicting `SELECT` statement. Ensure the column names and data types match.
CREATE PROCEDURE my_procedure (...) LANGUAGE SQLSCRIPT AS
BEGIN
-- Existing logic...
END RESULT VIEW my_result_view AS
SELECT column1, column2 FROM my_table WHERE condition;4
If the original `SELECT` statement was intended to perform transformations or aggregations, ensure these are replicated within the `RESULT VIEW` definition.
CREATE PROCEDURE my_procedure (...) LANGUAGE SQLSCRIPT AS
BEGIN
-- Existing logic...
END RESULT VIEW my_result_view AS
SELECT SUM(amount) AS total_amount, COUNT(*) AS record_count FROM my_table WHERE condition;5
Save and activate the modified SQLScript object.
3. Refactor SQLScript to Use Table Variables for Intermediate Results advanced
Use table variables within the SQLScript to store intermediate results, and then define the result view based on these variables.
1
Identify the SQLScript object and the `SELECT` statement causing the issue.
2
Declare a table variable within the `BEGIN...END` block of your SQLScript object to hold the results of the `SELECT` statement.
DECLARE temp_result TABLE (<column_definitions>);3
Insert the results of your `SELECT` statement into the declared table variable.
INSERT INTO :temp_result (column1, column2)
SELECT column1, column2 FROM my_table WHERE condition;4
Define the `RESULT VIEW` of your SQLScript object to select from this table variable.
CREATE PROCEDURE my_procedure (...) LANGUAGE SQLSCRIPT AS
BEGIN
DECLARE temp_result TABLE (column1 INT, column2 VARCHAR(100));
INSERT INTO :temp_result (column1, column2)
SELECT column1, column2 FROM my_table WHERE condition;
END RESULT VIEW my_result_view AS
SELECT column1, column2 FROM :temp_result;5
Ensure the column definitions in the table variable and the `RESULT VIEW` match the output of the original `SELECT` statement.
6
Save and activate the modified SQLScript object.
