 `--execute`<br>`-e` | Execute SQL statements directly from the command line, without opening a shell. This flag can be set multiple times, and each instance can contain one or more statements separated by semi-colons. If an error occurs in any statement, the command exits with a non-zero status code and further statements are not executed. The results of each statement are printed to the standard output (see `--format` for formatting options).
 `--format` | How to display table rows printed to the standard output. Possible values: `tsv`, `csv`, `table`, `raw`, `records`, `sql`, `html`.<br><br>**Default:** `table` for sessions that [output on a terminal](use-the-built-in-sql-client.html#session-and-output-types); `tsv` otherwise<br /><br />This flag corresponds to the `display_format` [client-side option](use-the-built-in-sql-client.html#client-side-options) for use in interactive sessions.
 `--safe-updates` | Disallow potentially unsafe SQL statements, including `DELETE` without a `WHERE` clause, `UPDATE` without a `WHERE` clause, and `ALTER TABLE ... DROP COLUMN`.<br><br>**Default:** `true` for [interactive sessions](use-the-built-in-sql-client.html#session-and-output-types); `false` otherwise<br><br>Potentially unsafe SQL statements can also be allowed/disallowed for an entire session via the `sql_safe_updates` [session variable](set-vars.html).

This flag may be specified multiple times, once per option.<br><br>After starting the SQL shell, the `\set` and `unset` commands can be use to enable and disable client-side options as well.
