Execute a query. To execute a query in the REPL, terminate the statement with a semicolon and press “ENTER”.
db>
select 5;{5}Alternatively, you can run the query without a semicolon by hitting Alt-Enter on Windows/Linux, or Esc+Return on macOS.
db>
select 5{5}Type Alt-Enter to run the query without having the cursor to the end of
the query.
This doesn’t work by default on macOS, however it’s possible to enable it with a quick fix.
in Terminal.app: Settings → Profiles → Keyboard → Check “Use Option as Meta key”
in iTerm: Settings → Profiles → Keys → Let Option key: ESC+
Alternatively you can use the esc+return shortcut.
Use query parameters. If your query contains a parameter, you will be prompted for a value.
db>
select 5 + <int64>$num;Parameter <int64>$num: 6
