How to insert a particular column data into a table in bigquery?

Question

I want the first column of the data which is present in a text file delimited by space. Is there any possible way to retrieve the column without including the whole text file as a table and filtering from that table?

Answer 1

You can use this command line

bq --location=US load \
--source_format=CSV \
--field_delimiter=" " \
--ignore_unknown_values \
<PROJECT_ID>:<DATASET>.<TABLE_NAME> \
./data.txt \
name:STRING 

You can change the file name, and the location. It's mandatory to set the schema in the command line to skip the other column in the autodetect mechanism.
