Description

This error signifies that an SQLScript declaration section within a procedure, function, or view contains multiple declaration statements. It commonly occurs during the activation or execution of database objects when the SQLScript parser encounters more than one variable or cursor declaration block.

💬

Error Message

At most one declaration is permitted in the declaration section

🔍

Known Causes

3 known causes

⚠️

Multiple DECLARE Blocks

An SQLScript procedure or function might inadvertently contain more than one `DECLARE` keyword or declaration block, leading to parser failure.

⚠️

Incorrect Declaration Scope

Variables or cursors are declared outside the allowed single `DECLARE` section, or within nested blocks where declarations are not permitted.

⚠️

Redundant Code Inclusion

During code refactoring or merging, multiple `DECLARE` sections from different parts of the code are unintentionally combined into a single scope.

Solutions

3 solutions available

1. Identify and Remove Duplicate Declarations in SQLScript easy

Locate and delete redundant variable or type declarations within your SQLScript code.

1

Open the SQLScript code that is triggering the error. This could be within a stored procedure, function, or other database object.

2

Examine the 'DECLARE' section at the beginning of your SQLScript. Look for any variable or type declarations that have the exact same name. The error message 'At most one declaration is permitted in the declaration section' directly points to this issue.

3

Delete all but one of the duplicate declarations. Ensure the remaining declaration is the correct one you intend to use.

Example of a duplicate declaration:
DECLARE my_variable INT;
-- ... other declarations ...
DECLARE my_variable INT; -- This is the duplicate

Corrected version:
DECLARE my_variable INT;
-- ... other declarations ...

4

Save and re-deploy the modified SQLScript object. Test to confirm the error is resolved.

2. Review and Refactor Complex SQLScript Logic medium

For more complex scripts, systematically analyze declarations and their scope to prevent accidental duplication.

1

If the SQLScript is large or has been modified by multiple developers, consider using a code editor with syntax highlighting and search capabilities to aid in identifying declarations.

2

Methodically review each 'DECLARE' statement. For each declared item (variable, cursor, exception, etc.), ensure its name is unique within the entire declaration section of that specific SQLScript unit. Pay attention to case sensitivity if your database configuration dictates it.

3

If you find a duplicated declaration, decide which one is the intended declaration. You might need to rename one of them or remove the redundant one entirely. Consider if the duplicated declaration was an oversight or if it was intended to represent different entities (which SQLScript doesn't allow with identical names).

4

After making corrections, thoroughly test the SQLScript with various input parameters and scenarios to ensure functional correctness and that the error is gone. Consider using SAP's built-in tools for debugging SQLScript if available.

3. Utilize Database Development Tools for Declaration Management medium

Leverage SAP's database development tools to automatically identify and assist in resolving declaration conflicts.

1

Open the SQLScript object in a SAP-specific development environment such as SAP Business Application Studio (BAS) or ADT (ABAP Development Tools) if you are working with ABAP-managed database procedures.

2

These IDEs often provide real-time syntax checking and error highlighting. The 'SAP S/4HANA Error 1285: Duplicate SQLScript Declaration' should be flagged directly in the editor.

3

Click on the highlighted error or hover over it to get more details. The tool should indicate the line numbers where the duplicate declarations are located.

4

Follow the IDE's suggestions or manually edit the code to remove the duplicate declaration as described in Solution 1. The IDE might offer auto-correction features.

5

Save, activate, and test the SQLScript object within the development environment. Ensure the error is resolved and the logic functions as expected.
