--- VALIDATION_MODE ------------------------------------------------

-- In Snowflake, the VALIDATION_MODE option in the COPY INTO command is used to validate data files without actually loading them into the table

-- Here are the different settings for VALIDATION_MODE:

-- RETURN_n_ROWS: Validates the data and returns up to n rows of results.
-- RETURN_ERRORS: Validates the data and returns any errors found.
-- RETURN_ALL_ERRORS: Validates the data and returns all errors found.

CREATE OR REPLACE TABLE MY_DB.PUBLIC.ORDERS (
ORDER_ID VARCHAR(30),
AMOUNT VARCHAR(30),
PROFIT INT,
QUANTITY INT,
CATEGORY VARCHAR(30),
SUBCATEGORY VARCHAR(30));

SELECT * FROM MY_DB.PUBLIC.ORDERS;

LIST @MANAGE_DB.INTERNAL_STAGES.order_Stage;

-- Load data using copy command

COPY INTO MY_DB.PUBLIC.ORDERS
FROM @MANAGE_DB.INTERNAL_STAGES.ORDER_STAGE
file_format = (type = csv field_delimiter=',' skip_header=1)
files = ('orders_dataset.csv.gz')
ON_ERROR = 'SKIP_FILE_3'
VALIDATION_MODE = RETURN_ERRORS;

COPY INTO MY_DB.PUBLIC.ORDERS
FROM @MANAGE_DB.INTERNAL_STAGES.ORDER_STAGE
file_format = (type = csv field_delimiter=',' skip_header=1)
files = ('orders_dataset.csv.gz')
ON_ERROR = 'SKIP_FILE_3'
VALIDATION_MODE = RETURN_ALL_ERRORS;

SELECT * FROM ORDERS;

COPY INTO MY_DB.PUBLIC.ORDERS
FROM @MANAGE_DB.INTERNAL_STAGES.ORDER_STAGE
file_format = (type = csv field_delimiter=',' skip_header=1)
files = ('orders_dataset_1.csv.gz')
