Snowflake SnowPro Certification Practice Test

What command can cause duplicate data to load into Snowflake?

1. COPY INTO

2. FORCE

3. LOAD DATA

4. INSERT INTO

The correct answer is: FORCE

The command that can cause duplicate data to load into Snowflake is the FORCE option in conjunction with COPY INTO. When using the COPY INTO command, you can apply the FORCE option to bypass certain checks that prevent the loading of duplicate data, particularly when loading from staged files. This means that if the data being loaded has been previously inserted, using FORCE will not prevent these duplicate entries from being added to the table. While the other commands listed have their specific functionalities, they either do not inherently cause duplications or are not related to the direct loading of data from external sources in the same way that COPY INTO does. For instance, the standard INSERT INTO command, while it can lead to duplicates if the inserted data already exists, does not have an explicit feature like FORCE that is designed to intentionally override duplicate checks during batch loading operations.
