Export from sqlite to csv using shell script

Question

I\'m making a shell script to export a sqlite query to a csv file, just like this:

 #!/bin/bash
./bin/sqlite3 ./sys/xserve_sqlite.db \".headers on\"
./bin/sq         


        

Answer 1

sqlite3

You have a separate call to sqlite3 for each line; by the time your select runs, your .out out.csv has been forgotten.

Try:

#!/bin/bash
./bin/sqlite3 ./sys/xserve_sqlite.db <

instead.

sh/bash methods

You can either call your script with a redirection:

$ your_script >out.csv

or you can insert the following as a first line in your script:

exec >out.csv

The former method allows you to specify different filenames, while the latter outputs to a specific filename. In both cases the line .output out.csv can be ignored.
