**Silent** is not a free pass: `DROP`, `TRUNCATE`, and a `DELETE` with no `WHERE` still raise the built-in dangerous query warning even there. So does a [Structure](/features/table-structure#saving-changes) save that drops a column, changes a column's type or character set, adds NOT NULL, changes the primary key, adds or rewrites a check constraint, converts a table's existing columns to another character set, or removes a MongoDB field. And **Read-Only** goes past queries to the interface itself, disabling inline cell editing, adding, deleting and duplicating rows, table truncate and drop, and import.
