Let’s see an example with the name internal stage. To verify if the file uploaded successfully, use the LIST command with the table stage as a parameter. LIST – To list the files from internal stages | simple_zipcodes.json | simple_ | 768 | 251 | NONE | GZIP | UPLOADED | | | source | target | source_size | target_size | source_compression | target_compression | status | message | ![]() You can find the JSON file at GitHub, download this file to a folder on your system, I’ve downloaded to /tmp folder.

PUT – Upload the file to Snowflake internal stage | Table ZIPCODE_JSON successfully created. Second, using COPY INTO, load the file from the internal stage to the Snowflake table.įirst, let’s create a table with one column as Snowflake loads the JSON file contents into a single column.ĬREATE TABLE ZIPCODE_JSON (ZIPCODE_RAW VARIANT).First, using PUT command upload the data file to Snowflake Internal stage. ![]() ![]() Loading a JSON data file to the Snowflake Database table is a two-step process.
