如何将 sql 文件传递给 gcloud sql 导出而不是内联 sql？

Question

I can export my data using

gcloud sql export csv .... --query='SELECT * FROM mytable'

My SELECT sql command is long and I'd like to pass it to gcloud in a file. I couldn't find anything in the docs about that. Is this possible to pass a file?

Answer 1

Try to use:

gcloud sql export csv .... --query=$(< x.sql)

where x.sql is the file with the SELECT statement.

Answer 2

using options shown here: https://unix.stackexchange.com/questions/393351/pass-contents-of-file-as-argument-to-bash-script

This worked:

--query="$(<myFile.sql)"

The answer @Piotr W. provided was just missing quotations.

Worth noting this method allowed me to put my SELECT statement with line breaks in a file vs providing the SELECT statement inline that could not have line breaks, making it hard to read and update.
