SAP S/4HANA Error 1332: Incorrect SQLScript Table Parameter
Description
This error occurs when a SQLScript built-in function receives an invalid first parameter. The function expects a column table or a projection view on column tables, but an incompatible type was provided. It typically arises during the development or execution of custom HANA SQLScript procedures or calculation views.
Error Message
Parameter must be a valid column table or projection view on column tables
Known Causes
3 known causesIncorrect Parameter Type
The first parameter passed to the SQLScript built-in function is of an incompatible data type, not a column table or a projection view.
Row Store Table Used
A row store table was provided as the first parameter when the built-in function specifically requires a column store table.
Invalid Table/View Reference
The referenced table or view in the SQLScript is misspelled, does not exist, or is not accessible in the current context.
Solutions
3 solutions available1. Validate Table Parameter Type in SQLScript Procedure easy
Ensure the table parameter in your SQLScript procedure is declared as a table type or a projection view on a column table.
1
Identify the SQLScript procedure that is raising error 1332. This procedure is likely being called with an incorrect table parameter.
2
Examine the procedure definition. The problematic parameter should be declared using the `TABLE` keyword, or it should be a projection view defined on a column table.
PROCEDURE "MY_PROCEDURE" ( IN my_input_table TABLE(column1 INT, column2 VARCHAR(100)), ... )3
If the parameter is not declared as `TABLE`, modify the procedure definition to use the `TABLE` keyword. For example, change `IN my_input TABLE(column1 INT)` to `IN my_input_table TABLE(column1 INT)`.
PROCEDURE "MY_PROCEDURE" ( IN my_input_table TABLE(column1 INT, column2 VARCHAR(100)), ... )4
If the parameter is intended to be a projection view, ensure that the view is indeed a projection view (i.e., it selects columns from underlying column tables) and that the view definition is correct.
CREATE VIEW "MY_PROJECTION_VIEW" AS SELECT column1, column2 FROM "MY_COLUMN_TABLE";5
Reactivate the modified SQLScript procedure in the SAP HANA database.
2. Correct Calling Context for SQLScript Procedures medium
Verify that the data being passed to the SQLScript procedure's table parameter matches the expected table type or projection view structure.
1
Locate the code or application that is calling the SQLScript procedure causing error 1332. This could be ABAP, another SQLScript procedure, or a client application.
2
Inspect the structure of the data being passed as the table parameter. It must conform to the definition of the table parameter in the called SQLScript procedure.
3
If the calling code is using a different table type or a temporary table that doesn't match, adjust the calling code to create a compatible table type or to populate a table that matches the procedure's expectation.
Example: If procedure expects TABLE(col1 INT, col2 VARCHAR(50)) and calling code provides TABLE(c1 INT, c2 VARCHAR(50)), rename columns in the calling code or create a temporary table with correct column names.4
If the calling code is passing a result set from a `SELECT` statement, ensure that the `SELECT` statement returns columns that exactly match the names and types of the table parameter in the SQLScript procedure. Using aliases for columns in the `SELECT` statement is crucial here.
CALL "MY_PROCEDURE" ( my_input_table => (SELECT col_a AS column1, col_b AS column2 FROM "SOURCE_TABLE") );5
Re-execute the calling application or code to test the fix.
3. Recreate or Verify Underlying Column Tables and Views advanced
Ensure that the column tables and any projection views referenced by the table parameter are correctly defined and exist.
1
Identify the column tables or projection views that the table parameter in your SQLScript procedure is expected to be based on. This information can be found within the procedure's definition or by analyzing the application logic.
2
Connect to the SAP HANA database using a suitable client tool (e.g., SAP HANA Studio, DB Browser for SAP HANA, or `hdbsql`).
3
Query the system views to verify the existence and structure of the relevant column tables. Ensure they are of type `COLUMN TABLE`.
SELECT TABLE_NAME, TABLE_TYPE FROM "SYS"."TABLES" WHERE TABLE_NAME = 'YOUR_COLUMN_TABLE_NAME';4
If projection views are involved, verify their definitions. A projection view should select directly from one or more column tables.
SELECT VIEW_NAME, DEFINITION FROM "SYS"."VIEWS" WHERE VIEW_NAME = 'YOUR_PROJECTION_VIEW_NAME';5
If the underlying column tables or projection views are missing, corrupted, or incorrectly defined, consider recreating them based on the original design. This might involve re-running application setup scripts or consulting with the development team.
6
After any necessary corrections to the underlying objects, re-activate the SQLScript procedure and re-test the calling application.
