Step 4: Set value correctly

Use queryValue() or valueStr() instead of hardcoded strings.

Step 5: Execute and test

Run the query and check SQL execution plans.

This step-based approach is recommended in MicroSoft Ax Training sessions.

Best Practices (D365 AX tech)

Always use queryValue() to prevent SQL injection. Avoid using wildcards unless necessary.

Prefer indexed fields for ranges. Combine ranges logically instead of stacking unnecessary conditions.

Clear ranges before reusing query objects. This avoids unexpected filtering.

Many developers improve these habits through MicroSoft Dynamics Ax Training Online practice labs.

Common Mistakes

Using string concatenation in ranges is a common error. Another mistake is using like operators on numeric fields.

Developers also forget to clear old ranges when reusing queries.
