COPY INTO is a powerful command in Snowflake that allows users to quickly and easily load data into their Snowflake databases. By default, Snowflake will allow blank values to be loaded into databases when using COPY INTO. However, users can easily prevent blank values from being loaded into their databases by using the command’s “ON_ERROR” option.
The ON_ERROR option allows users to specify what action should be taken if an error is encountered when loading data into a database. By setting the ON_ERROR option to “SKIP_FILE”, Snowflake will skip any files that contain blank values when loading data into a database. This will ensure that only valid data is loaded into the database and that blank values are not loaded.
Additionally, users can also use the ON_ERROR option to specify what action should be taken if an error is encountered when loading data into a database. This allows users to customize how Snowflake handles errors when loading data into a database, ensuring that their data is loaded correctly and that any errors are handled appropriately.
