How to Show Line Numbers in SAP HANA Studio: The Ultimate Guide

SAP HANA Studio (based on Eclipse) remains a critical development environment for many HANA developers, even with the rise of SAP Business Application Studio and Web IDE. One of the most common, yet surprisingly tricky, settings for new users is displaying line numbers in the SQL Script editor. Displaying Line Numbers in SAP HANA Studio By

Line numbers are indispensable for debugging, code reviews, and pair programming. When an error message says, "Error at position XYZ in line 24," you need to see those lines instantly.

Below is a step-by-step guide to enabling line numbers, troubleshooting why they might not appear, and customizing the editor for maximum productivity.

3. Use Cases and Benefits

Enabling line numbers provides critical support during the development lifecycle: Open SAP HANA Studio : Launch SAP HANA Studio on your system

• SQL Error Resolution: When a SQL syntax error occurs, the HANA database returns an error message (e.g., Syntax error: incorrect syntax near "FROM": line 4, col 15). Having line numbers visible allows the developer to jump immediately to the identified location.
• Code Reviews: During peer reviews, referencing specific lines (e.g., "Please check the logic at line 25") is more precise than describing the location textually.
• Debugging: When setting breakpoints in stored procedures or scripts, the debugger interface relies on line numbers to indicate where execution has paused.

✅ How to enable line numbers

1. Open SAP HANA Studio.
2. Go to Window → Preferences.
3. Navigate to General → Editors → Text Editors.
4. Check the box “Show line numbers”.
5. Click Apply and Close.

Line numbers will now appear in the left gutter of SQL editors, console views, and other text editors.

Step-by-Step Instructions:

1. Launch SAP HANA Studio and log into your system (if required).
2. Open the Preferences Window:
   • Windows/Linux: Click Window in the top menu bar, then select Preferences from the dropdown.
   • macOS: Click SAP HANA Studio in the Apple menu bar, then select Preferences.
3. Navigate to the Text Editors Section:
   • In the left-hand tree menu of the Preferences dialog, expand the General node.
   • Under General, click on Editors.
   • Then, click on Text Editors.
4. Locate the Line Number Checkbox:
   • In the right-hand panel (titled "Text Editors"), look for a section labeled "Appearance options".
   • Find the checkbox that reads: Show line numbers.
5. Enable and Apply:
   • Check the Show line numbers box.
   • Click Apply and Close at the bottom of the dialog.

Result: All open and future text-based editors (including SQLScript editors, .hdb files, and plain .sql files) will now display a vertical ruler with line numbers on the left margin.

Note for SAP HANA 2.0 SPS 05+: This method works identically across all versions. If you are using the newer SAP HANA Database Explorer (Web IDE) , line numbers are usually enabled by default in the browser-based editor.

Problem 3: Using an Outdated Version of SAP HANA Studio

• Issue: Versions older than HANA Studio 1.0 SP10 (circa 2014) had bugs where line number settings did not persist across sessions.
• Solution: Upgrade to the latest available SAP HANA Studio version (2.0 SPS07 or newer) or migrate to SAP Business Application Studio (BAS) or HANA Database Explorer.

2. Enabling "Print Margin" (Vertical Guide Line)

A print margin is a vertical line that helps you keep code within a certain width (e.g., 80 or 120 characters). This is extremely useful when line numbers are visible.

• Go to Preferences > General > Editors > Text Editors.
• Under "Print margin column", enter 120 (or your preferred limit).
• Check Show print margin.

When line numbers are on, the print margin sits to the right, and the line numbers sits on the left, creating a professional coding layout.
