# Step 4. Copy Data into the Target Table¶

Execute COPY INTO <table> to load your staged data into the target table.

Note that this command requires an active, running warehouse, which you created as a prerequisite for this tutorial. If you don’t have access to a warehouse, you will need to create one now.

COPY INTO emp_basic
FROM @%emp_basic
FILE_FORMAT = (type = csv field_optionally_enclosed_by='"')
PATTERN = '.*employees0[1-5].csv.gz'
ON_ERROR = 'skip_file';


Let’s look more closely at this command:

• The FROM clause identifies the internal stage location.

• FILE_FORMAT specifies the file type as CSV, and specifies the double-quote character (") as the character used to enclose strings. Snowflake supports diverse file types and options. These are described in CREATE FILE FORMAT. The example COPY statement accepts all other default file format options.

• PATTERN applies pattern matching to load data from all files that match the regular expression .*employees0[1-5].csv.gz.

• ON_ERROR specifies what to do when the COPY command encounters errors in the files. By default, the command stops loading data when the first error is encountered; however, we’ve instructed it to skip any file containing an error and move on to loading the next file. Note that this is just for illustration purposes; none of the files in this tutorial contain errors.

The COPY command also provides an option for validating files before you load them. See the COPY INTO <table> topic and the other data loading tutorials for additional error checking and validation instructions.

Snowflake returns the following results:
