I have multiple in .CSV files in Google cloud storage but I am unable to push data into table because number of columns in .CSV files are different.
Let's say I have 10 .CSV files with columns A, B, C, D, and I have another 10 .CSV files with columns A, B, D.
When I push .CSV files into Big Query table, I want to create to A column to A , B column To B, C column to C and making NULL for other 10 .CSV, D column to D .
Lets Suppose 10 .CSV files have column :
NAME, DOB, GENDER, MOBILE NO.
Dan , 12/08/1999, MALE, 1234567889
Oliver, 17/03/19998, MALE, 5267382736
Another 10 .CSV file have column :
NAME, DOB, MOBILE NO.
Akash, 12/02/1999, 1234567889
Ram, 17/09/19998, 5267382736
But In Big Query Table Final result i want:
NAME, DOB, GENDER, MOBILE NO.
Dan , 12/08/1999, MALE, 1234567889
Oliver, 17/03/19998, MALE, 5267382736
Akash, 12/02/1999, 1234567889
