One of the values you can provide to the .mode dot command when using the SQLite command line shell is line.

November 7, 2021April 13, 2020 by Ian

SQLite has several modes and settings that enable you to output query results as a comma-separated list.

For example, you can use the .separator dot command to specify a comma as the separator. Or you could use the “quote” mode to format the output as string literals.

However, for the purposes of this article, I’m going to use csv mode, which formats the results as a comma-separated list, as well as with double quotes around strings. Internal double quotes are double-quoted.
