Worked example. The correct answer is already marked and every option is explained below, so there is nothing to select here. To answer questions yourself, start the free trial.
A data analyst is using a BigQuery notebook (Colab Enterprise) to analyze sales performance across retail regions. In an earlier Python code cell, the analyst defined a numerical threshold:
StudyCerts
StudyCertssales_threshold = 10000
The analyst now wants to execute a query in a dedicated SQL cell to retrieve all records from sales_dataset.orders where order_total exceeds this value.
How should the analyst reference the Python variable inside the SQL cell query?
In BigQuery notebooks and Colab Enterprise, SQL cells provide native integration with the Python notebook environment. By enclosing a Python variable or a BigQuery DataFrame name in curly braces ({ }), users can dynamically inject Python state directly into GoogleSQL query statements.
{sales_threshold} in the SQL cell query evaluates the Python variable defined in the earlier cell and substitutes its numerical value (10000) into the WHERE clause before query dispatch.SELECT * FROM {df}) to iteratively refine analytical pipelines.This is the built-in, native GoogleSQL parameterization syntax supported by Colab Enterprise in Google Cloud console. It eliminates the need to instantiate a bigquery.Client() or construct formatted SQL strings in Python code cells.
