--- toc_title: INTO OUTFILE --- # INTO OUTFILE Clause {#into-outfile-clause} Add the `INTO OUTFILE filename` clause (where filename is a string literal) to `SELECT query` to redirect its output to the specified file on the client-side. ## Implementation Details {#implementation-details} - This functionality is available in the [command-line client](../../../interfaces/cli.md) and [clickhouse-local](../../../operations/utilities/clickhouse-local.md). Thus a query sent via [HTTP interface](../../../interfaces/http.md) will fail. - The query will fail if a file with the same filename already exists. - The default [output format](../../../interfaces/formats.md) is `TabSeparated` (like in the command-line client batch mode).
