Rows can be added, edited or deleted when the database is writable and the table has a stable row identity. Views and tables without one are read-only.
With structured write access, the Structure tab can add a column. SQLite 3.25 or later can rename one, and SQLite 3.35 or later can drop one. SQLite refuses to drop columns used by constraints, indexes or other schema objects. Changing a column's type or constraints requires rebuilding the table with Execute SQL.
The buttons at the bottom rename a table or, after confirmation, drop a table or view. This module cannot recover a dropped table or its rows.
