Re: SQLite3 API support

[Hideki IWAMOTO]

Hi. Yamaguchi san.

When I use the sqlite3 format tag file, "global -x main" runs forever.

You wrote the following comment in dbop3_first() and dbop3_next().

  Sqlite3 returns SQLITE_MISUSE if it is called after SQLITE_DONE.

However, in my environment, SQLITE_ROW is returned instead of SQLITE_MISUSE.
