Step 6. Summary and Clean Up

Congratulations! You have successfully completed this introductory tutorial.

Take a few minutes to review a short summary and the key points covered in the tutorial. You might also want to consider cleaning up by dropping any objects you created in the tutorial. And, at the bottom of the page, we provide some links to other topics in the Snowflake Documentation that you can use to learn more.

Tutorial Summary and Key Points

In summary, data loading is performed in 2 steps:

  1. Stage the data files to load. The files can be staged internally (in Snowflake) or in an external location. In this tutorial, you stage files in an internal stage.

  2. Copy data from the staged files into an existing target table. A running warehouse is required for this step.

Some key points to remember about loading CSV files:

  • A CSV file consists of 1 or more records, with 1 or more fields in each record, and sometimes a header record.

  • Records and fields in each file are separated by delimiters. The default delimiters are:


    newline characters



    In other words, Snowflake expects each record in a CSV file to be separated by newlines and the fields (i.e. individual values) in each record to be separated by commas. If different characters are used as record and field delimiters, you must explicitly specify this as part of the file format when loading.

  • There is a direct correlation between the fields in the files and the columns in the table you will be loading, in terms of:

    • Number of fields (in the file) and columns (in the target table).

    • Positions of the fields and columns within their respective file/table.

    • Data types, such as string, number, or date, for fields and columns.

    If the numbers, positions, and data types don’t all align, the records will not be loaded.


    Snowflake supports loading files in which the fields don’t exactly align with the columns in the target table; however, this is a more advanced data loading topic (covered in Transforming Data During a Load).

Tutorial Clean Up (Optional)

Execute the following DROP <object> statements to return your system to its state before you began the tutorial:



Exit the Connection

To exit a connection, use the !exit command for SnowSQL (or its alias, !disconnect).
