Is it possible to use an input file with the bigquery CLI?
bq query < my_query.sql
回答1:
If you're using unix (or have cygwin installed on windows), you can use xargs:
xargs -a my_query.sql -0 bq query
Alternately you can use back-ticks:
bq query `cat my_query.sql`
Note that bq can only process one command at a time -- if your .sql script has several queries, you'll need to split the file on ;

On windows I am using this method. Prerequisite is to have each command listed in a single row. This will process each command in row one by one using bq.
