On-prem Connector for Generic Databases - Is there a character limit for the Get Users SQL Statement field?

this is the configuration screen.

Hello @GayeongS.93038 (Customer)​ Thank you for posting on our Community page!

Okta does not explicitly publish a hard character limit for the SQL Statement field in the On-premises Provisioning Connector for Generic Databases, but standard configuration text fields generally allow up to 4,000 characters. Exceeding the limit results in an API validation error or an input cap. To avoid limits with complex queries, shift the logic to the database layer using a stored procedure or a database view.

What is the character limit for the SQL Statement field?

Standard configuration text fields in the Okta Admin Console generally allow large inputs, often up to 4,000 characters or more depending on the underlying API schema. While standard SELECT, INSERT, UPDATE, and DELETE operations fit within this limit, a massive query with heavy formatting, multiple nested JOIN operations, or complex inline logic could potentially hit backend payload limits.

What happens if the character limit is exceeded?

If a query is too long, it does not fail silently or execute a truncated query. The Okta configuration interface relies on API validation. Exceeding the maximum allowed length results in specific validation behaviors.

• Save Failure: When Save is selected, the Okta user interface throws a validation error, such as an API error like 400 Bad Request or a string too long message, preventing the configuration from saving.
• Input Cap: The text box stops accepting new characters once the client-side limit is reached.

How are complex queries managed to avoid character limits?

If a query is large enough to risk hitting a character limit, shift the logic out of Okta and into the database layer. This approach is easier to maintain, test, and troubleshoot. Implement this by using a stored procedure or a database view.

• Use a Stored Procedure: In the Okta Provisioning tab, switch the configuration option from SQL Statement to Stored Procedure. Encapsulate the complex logic in the database, and reference the procedure name in Okta.
• Use a Database View: Build a view in the database that handles all complex joins and data transformations. Keep the Okta SQL Statement short by querying the view directly.
