<p> ^The filename in the INTO clause can be an arbitrary SQL expression that evaluates to a string. ^The file named by the INTO clause must not previously exist, or else it must be an empty file, or the VACUUM INTO command will fail with an error. <p> The VACUUM INTO command is transactional in the sense that the generated output database is a consistent snapshot of the orgininal database. However, if the VACUUM INTO command is interrupted by a unplanned shutdown or power lose, then the generated output database might be incomplete and corrupt. Also, SQLite does not invoke fsync() or FlushFileBuffers() |
