Snowflake SnowPro Certification Practice Test

In a Copy function, is it possible to insert on a SELECT against a staged file using a WHERE clause?

1. True

2. False

3. Only in specific scenarios

4. Depends on the file type

The correct answer is: True

The ability to use a WHERE clause in a SELECT statement when utilizing the Copy function to insert data from a staged file in Snowflake is indeed supported. This means you can filter the data being loaded based on specific conditions defined in the WHERE clause, allowing for more control and flexibility over the data you are inserting into your target table. When you use the Copy command, Snowflake pulls the data from the staged file, and if a SELECT statement is provided along with a WHERE clause, it enables you to conditionally include only those rows that meet the specified criteria. This is particularly useful when you only want to import a subset of data that matches certain conditions, thereby enhancing efficiency and reducing unnecessary data loading. While this approach grants more versatility in loading processes, it's important to ensure that the staged files and the schema of the target table align with the conditions specified in the WHERE clause to avoid any runtime issues. Hence, stating that it is possible to insert on a SELECT against a staged file using a WHERE clause is indeed accurate.
