SAP HANA 2.0 SPS06 SQLScript for SAP HANA – HA150 — Lesson 2: Declarative and Imperative Logic, Table Variables, Cursors, Dynamic SQL, and Error Handling

Learning Objectives

• Explain the SAP structures, data, settings, roles, and dependencies governing declarative and imperative SQLScript.
• Perform and validate table variables, dynamic SQL, and exceptions using reviewable system evidence.
• Evaluate the condition where a procedure returns correct results on sample data but performs poorly or inconsistently because execution plans, cardinality, parallelization, and error handling are weak and select proportionate corrective action.

Detailed Topics

• Declarative and Imperative Logic applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Table Variables applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Cursors applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Dynamic SQL applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• and Error Handling applied to the course scenario, expected SAP behavior, dependencies, and evidence.

Instructor Demonstration

The instructor traces a data-development team moving complex transformations and analytical calculations into maintainable HANA database logic. The walkthrough connects navigation, configuration or process logic, system messages, and evidence captured in the HA150 SQLScript design, test, trace, and optimization portfolio. It also tests the exception where a procedure returns correct results on sample data but performs poorly or inconsistently because execution plans, cardinality, parallelization, and error handling are weak.

Hands-On Exercise

Complete a controlled SAP exercise covering Declarative and Imperative Logic, Table Variables, Cursors, Dynamic SQL, and Error Handling and preserve the verified result in the HA150 SQLScript design, test, trace, and optimization portfolio.

1. Confirm scope, prerequisites, master data, roles, dependencies, and acceptance criteria.
2. Execute the workflow while recording settings, transactions, outputs, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception.
4. Document corrections, evidence, ownership, retest criteria, and handover actions.

Scenario Analysis

• Identify which object, rule, setting, or process step most strongly influences declarative and imperative SQLScript.
• Compare two defensible responses and explain business, technical, control, and support trade-offs.
• Determine how the HA150 SQLScript design, test, trace, and optimization portfolio should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected SAP behavior first differs from the observed result. Check master data, configuration sequence, authorization, integration, status, and transaction evidence separately. Treat “a procedure returns correct results on sample data but performs poorly or inconsistently because execution plans, cardinality, parallelization, and error handling are weak” as a hypothesis until system settings, logs, documents, and outcomes confirm the cause.

Validation Checklist

• Required SAP structures, master data, roles, settings, and dependencies are present.
• The HA150 SQLScript design, test, trace, and optimization portfolio connects each conclusion to objective, reviewable evidence.
• Normal processing, the boundary condition, integration behavior, and exception were tested.
• Corrections, ownership, retest criteria, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply Declarative and Imperative Logic, Table Variables, Cursors, Dynamic SQL, and Error Handling, explain the resulting SAP behavior, and defend the outcome through the HA150 SQLScript design, test, trace, and optimization portfolio.
