SAP SQLScript Development Guide
Overview
SQLScript is SAP HANA's procedural extension to SQL, enabling complex data-intensive logic execution directly within the database layer. It follows the code-to-data paradigm, pushing computation to where data resides rather than moving data to the application layer.
Key Characteristics
- Case-insensitive language
- All statements end with semicolons
- Variables use colon prefix when referenced (
:variableName) - No colon when assigning values
- Use
DUMMYtable for single-row operations
Two Logic Types
| Type | Description | Execution |
|---|---|---|
| Declarative | Pure SQL sequences | Converted to data flow graphs, processed in parallel |
| Imperative | Control structures (IF, WHILE, FOR) | Processed sequentially, prevents parallel execution |
