Exam SnowPro Core topic 1 question 11 discussion

The correct answer is FALSE. The file format can be defined at the stage, table, or copy into command. Create Stage: https://docs.snowflake.com/en/sql-reference/sql/create-stage.html Create Table (STAGE_FILE_FORMAT option): https://docs.snowflake.com/en/sql-reference/sql/create-table.html Copy Into: https://docs.snowflake.com/en/sql-reference/sql/copy-into-table.html

False. In Snowflake, the COPY command does not necessarily require specifying a File Format in order to execute. The COPY command can be used to load data into a table from various file formats such as CSV, JSON, Avro, Parquet, etc. When a file format is not explicitly specified in the COPY command, Snowflake attempts to automatically infer the file format based on the file's extension or internal file structure. This automatic file format inference feature is known as "automatic file format detection." However, if the file format cannot be determined automatically or if you want to override the automatic detection, you can explicitly specify a File Format in the COPY command using the FILE_FORMAT parameter. So, while specifying a File Format can provide more control and customization over the data loading process, it is not mandatory for the COPY command to execute successfully.

It is not mandatory to specify a FILE FORMAT for COPY operations. While it is not mandatory a FILE FORMAT should always be created for COPY into <table> operations and file unloading and COPY into <location> operations. Automatic inference should only be used with small sets of data and for testing or low importance data.

False, it's possible but not neccesary.

A.True

correct answer:B

It is optional

In the COPY command, the File_Format is not mandatory. With the Internal Named Stage you can specify file_format during creation of the stage

True-A

A.True

B is correct

file format is nor mandatory

The answer is FALSE. According to snowflake documentation, FILE FORMAT is an optional parameter. https://docs.snowflake.com/en/sql-reference/sql/copy-into-table#required-parameters

Correct Answer is B. Specifying FILE Format is not pre-requisite. see below Copy command e.g -- S3 bucket COPY INTO mytable FROM 's3://mybucket/./../a.csv'; -- Google Cloud Storage bucket COPY INTO mytable FROM 'gcs://mybucket/./../a.csv'; -- Azure container COPY INTO mytable FROM 'azure://myaccount.blob.core.windows.net/mycontainer/./../a.csv';

Answer is B as it optional to provide in here as we can provide it later part also at stage or table level.

A.The COPY command must specify a File Format in order to execute

The answer is FALSE. According to snowflake documentation, FILE FORMAT is an optional parameter. https://docs.snowflake.com/en/sql-reference/sql/copy-into-table#required-parameters
