Execution Constraints

Execution constraints define the structural boundaries of a VQL statement. These limits prevent excessively complex queries from impacting system performance.

Query Length

Section link for Query Length

The maximum length of a VQL query string is 50,000 characters. This limit applies to the entire statement sent in the q parameter of a POST request to the /query endpoint.

Functional Constraints

• Aggregates: VQL does not support standard SQL aggregate functions like SUM, AVG, or COUNT within the SELECT clause (except for specific specialized endpoints).
• Subquery Nesting: You cannot nest a subquery inside another subquery. VQL only supports one level of nesting for relationship joins.
