BigQuery FAQs

Question 1

Can I validate BigQuery SQL queries that use parameters?

Accepted Answer

Yes, the tool fully supports validating and performing dry-run analysis on parameterized BigQuery SQL queries. You can provide parameter values as part of your input for accurate checks.

Question 2

Does this tool execute BigQuery queries?

Accepted Answer

No, absolutely not. A core feature of this tool is that it only performs dry-runs and syntax validation. It explicitly does NOT execute any BigQuery queries, ensuring safety and preventing unexpected charges.

Question 3

What is the primary function of this BigQuery tool?

Accepted Answer

This tool primarily validates BigQuery SQL syntax and performs dry-run analyses to estimate query costs, identify referenced tables, and preview schemas without actually executing the queries.

Question 4

How accurate are the cost estimates provided?

Accepted Answer

The cost estimates are approximations based on the estimated bytes processed during the dry-run. While highly useful for budgeting and optimization, they should be considered estimates rather than exact final costs.

Question 5

What kind of metadata does the dry-run analysis provide?

Accepted Answer

The dry-run analysis provides the total bytes that would be processed, a USD cost estimate, a list of all referenced tables, and a schema preview of the query's output, all without executing the query.
