COF-C03 Data Loading, Unloading, and Connectivity Practice Question
A data analyst needs to unload the results of a query from a Snowflake table to a local machine. The analyst wants to use the Snowflake web interface (Snowsight) to download the data as a CSV file. Which of the following is the correct approach?
⚠ Common exam trap
The trap here is overcomplicating the task by assuming that a COPY INTO or GET command is necessary when the web interface already offers a direct download option.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run the query in a worksheet, then use the 'Download results' button to save the output as a CSV file.
Snowsight provides a built-in feature to download query results as a CSV file. After executing a query, the results pane includes a 'Download results' button, which exports the displayed data to a CSV file on the local machine. This is the simplest and most direct method for ad-hoc downloads, especially for smaller datasets, and it does not require staging or command-line tools.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a named internal stage, unload the data using COPY INTO @stage, then use GET to download the file to the local machine.
Why it's wrong here
This method is valid but requires multiple steps: creating a stage, unloading, and then using the GET command in SnowSQL or the Snowflake CLI. It is not the direct approach available in Snowsight. The question specifies using the web interface, so the download button is more appropriate.
- ✗
Execute a COPY INTO command targeting a local file path, then download the file from the user's home directory.
Why it's wrong here
COPY INTO can only unload data to a Snowflake stage (internal or external), not directly to a local file path. The user would need to unload to a stage and then download from there. This option incorrectly suggests a direct local path, which is not supported.
- ✓
Run the query in a worksheet, then use the 'Download results' button to save the output as a CSV file.
Why this is correct
In Snowsight, after running a query, the results grid provides a 'Download results' button that allows downloading the result set as a CSV file directly to the local machine. This is a straightforward and supported method for small to medium result sets, and it requires no additional staging or commands.
- ✗
Use the Snowflake REST API to execute the query and retrieve the results as a CSV stream.
Why it's wrong here
The Snowflake REST API (SQL API) can return results in JSON format, but it does not directly provide a CSV stream. It is also a programmatic approach, not a manual download via the web interface. This is overly complex for the analyst's need and not the intended method in Snowsight.
