You can remove this line after modifying @input_data_1.

Change to 'customer_data'.

You can remove this & use @output_data_1_name = 'customer_data' instead. This will output the dataframe back to SQL.

Change to CREATE OR ALTER and remove the DROP PROCEDURE IF EXISTS.

Seems like there is no newline here or there is some special character. Can you add a carriage return after ; to make sure it runs?

I think it should be column_info all lowercase.

You can remove this line. It is not needed since we are not using SQL compute context.

I see some special character at the end. Can you add carriage return at end?
