SAP S/4HANA Error 1351: Invalid SQLScript Parse Tree
Description
This error indicates that the SAP HANA database encountered a problem parsing SQLScript code. It commonly occurs when executing or activating database objects like stored procedures, calculated views, or functions within the SAP S/4HANA environment, suggesting a syntax or structural issue in the underlying SQLScript.
Error Message
ERR_SQLSCRIPT_INVALID_PARSE_TREE
Known Causes
3 known causesMalformed SQLScript Syntax
The SQLScript code contains syntax errors, such as missing keywords, incorrect punctuation, or improper function calls, preventing the parser from understanding the statement.
Invalid Database Object References
The SQLScript code attempts to reference database objects (tables, views, procedures) that do not exist or are not accessible in the current schema or context.
Data Type or Column Mismatch
SQLScript references tables, columns, or variables with incompatible data types or non-existent names, leading to a parse tree that cannot be resolved.
Solutions
3 solutions available1. Recompile the Affected SQLScript Object easy
Invalid parse trees often indicate corruption or inconsistencies, and recompilation is the most direct fix.
1
Identify the specific SQLScript object (e.g., stored procedure, function, view) that is causing the error. This can usually be determined from the surrounding error messages or logs.
SELECT OBJECT_NAME, OBJECT_TYPE FROM SYS.OBJECTS WHERE STATUS = 'INVALID';2
Connect to your SAP HANA database using a suitable client tool (e.g., SAP HANA Studio, DB Explorer in SAP BTP Cockpit, hdbsql).
3
Execute the RECOMPILE command for the identified object. Replace `your_schema` and `your_object_name` with the actual schema and name of the SQLScript object.
RECOMPILE "your_schema"."your_object_name";4
If the object is a procedure or function, you might need to explicitly recompile it using its full signature.
RECOMPILE "your_schema"."your_object_name"(parameter1_type, parameter2_type);5
Verify that the object's status is now 'VALID'.
SELECT OBJECT_NAME, OBJECT_TYPE, STATUS FROM SYS.OBJECTS WHERE OBJECT_NAME = 'your_object_name';2. Review and Correct SQL Syntax Errors medium
A malformed SQL statement within the SQLScript can lead to an invalid parse tree.
1
Locate the SQLScript code that is failing. This might be within a stored procedure, function, or a dynamically executed SQL statement.
2
Carefully examine the SQL syntax within the script. Pay close attention to:
- Missing or mismatched parentheses.
- Incorrect keyword usage.
- Typos in table or column names.
- Improper use of operators.
- Incorrect data type conversions.
- Missing or mismatched parentheses.
- Incorrect keyword usage.
- Typos in table or column names.
- Improper use of operators.
- Incorrect data type conversions.
3
Use a SQL editor with syntax highlighting and validation features (e.g., SAP HANA Studio's SQL editor, VS Code with HANA extensions) to help identify syntax issues.
4
If the SQLScript is part of a custom development, review the ABAP or other application code that is generating or executing this SQLScript to ensure it's constructing valid SQL.
5
After correcting the syntax, recompile the SQLScript object as described in the 'Recompile the Affected SQLScript Object' solution.
3. Check for Version Incompatibilities or Patches advanced
Sometimes, bugs in specific HANA versions or missing patches can cause parsing issues.
1
Determine the exact SAP HANA database version and revision you are running. This can be found in SAP HANA Studio's system information or by executing a SQL query.
SELECT * FROM SYS.M_REVISION_DIAGNOSTICS;2
Consult SAP Notes and the SAP Support Portal for any known issues related to 'ERR_SQLSCRIPT_INVALID_PARSE_TREE' for your specific HANA version and revision.
3
If a relevant SAP Note is found, follow the instructions to apply any necessary patches or workarounds. This might involve updating the HANA database itself or specific components.
4
If the issue appears to be a bug, consider raising a support incident with SAP, providing detailed information about the error, the affected object, and your HANA environment.
