Salesforce has introduced a much-needed enhancement to its dynamic SOQL queries—support for negative currency values. This new feature opens up opportunities for querying currency fields where negative amounts need to be filtered, especially in scenarios like refunds, returns, or any other cases where negative values are involved. Previously, such queries would have resulted in an error, but now, they are supported in dynamic Apex and queries executed via APIs.
What Changed?
Prior to this update, Salesforce did not support negative currency values in dynamic SOQL queries, causing developers to face limitations when dealing with negative financial data. Any attempt to filter for a negative amount would result in a query failure. Now, with this new update, Salesforce enables developers to query negative values effortlessly in orgs where MultiCurrency is enabled.
Dynamic SOQL Example:
Here's an example of a dynamic SOQL query that would have previously failed but now works with negative currency values:
String queryString = 'SELECT Amount FROM Opportunity WHERE Amount < USD-5000';
List<SObject> results = Database.query(queryString);
System.debug(results);
In this query, the Amount field is filtered to only return opportunities where the amount is less than -5000 USD. This capability now makes it easier to handle cases involving financial losses, returns, or adjustments.
Key Considerations:
Dynamic SOQL vs. Static SOQL: It's important to note that this support for negative currency values is only available in dynamic SOQL. Static SOQL still does not support filtering negative values with currency fields.
MultiCurrency Org Requirement: To make full use of this feature, your Salesforce org must have MultiCurrency enabled. Without MultiCurrency, negative currency values might not behave as expected in SOQL queries.
API Support: This feature is not limited to Apex. You can also use it in any queries executed via APIs, making integration scenarios with external systems easier when dealing with negative financial data.
Conclusion
With negative currency support in dynamic SOQL, Salesforce developers can now handle complex financial datasets more effectively. Whether it's for reporting purposes or specific business logic, this change allows more flexibility in querying and processing data, especially for organizations that regularly manage refunds or negative balances.
