<p>Query or change the secure-delete setting.)^ ^When secure-delete
on, SQLite overwrites deleted content with zeros. ^The default
setting is determined by the [SQLITE_SECURE_DELETE]
compile-time option.
<p>
^This pragma sets or clears the secure-delete flag when the pragma is
prepared, not when the resulting prepared statement is run. ^The
prepared statement for this pragma merely returns the value of the
secure-delete setting at the time the statement was prepared. One should
not retain or reuse the prepared statement for this pragma.
<p>
^When there are [ATTACH | attached databases] and no database
is specified in the pragma, all databases have their secure-delete
setting altered and the return value is the value of the main database.
^The secure-delete setting for newly attached databases is the setting
of the main database at the time the ATTACH command is evaluated.
<p>
^When multiple database connections share the same cache, changing
the secure-delete flag on one database connection changes it for them
all.
