Question 10

  • A

    'myvar'

  • B {{myvar}}
Reveal correct answer

Correct answer: B

Explanation

✅ {{myvar}}

Explanation:

In Snowflake Notebooks, you can reference Python variables inside SQL cells using Jinja-style syntax, which means wrapping the variable name in double curly braces: {{myvar}}. This allows dynamic substitution of Python values directly into SQL queries, enabling flexible and interactive workflows across cell types.

❌ Why the other options are incorrect?

  • 'myvar' → Incorrect, as this is not valid syntax and would likely result in a SQL parsing error.

  • $myvar → Incorrect, because Snowflake Notebooks do not use shell-style variable substitution.

  • myvar → Incorrect, since referencing the variable without curly braces won’t trigger substitution—it will be interpreted as a literal column or identifier.
