Format SQLite Query Results as a Comma-Separated List

by

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.

You can do this by switching to “quote” mode. When you do this, strings are enclosed in single-quotes and internal single-quotes are escaped by doubling. Also, blobs are displayed in hexadecimal blob literal notation, numbers are displayed as ASCII text, and NULL values are shown as “NULL”.

If you need to format your results with double quotes, consider using csv mode.

Fortunately, there’s an easy way to format the output so that it’s displayed as a column with column headers.
