The email message above is correct for the sqlite3_exec() interface. In other words sqlite3_exec() will automatically reparse and retry the query statement. The sqlite3_step() interface may or may not reparse and retry the query statement depending on how it was originally prepared. The retry occurs if sqlite3_prepare_v2() was used. There is no retry if sqlite3_prepare() was used. In all cases, there is a limited number of retries. If the schema keeps changing faster than sqlite3_exec() or sqlite3_step() is able to reparse and retry the statement, then it eventually gives up and returns SQLITE_SCHEMA. > Manohar > > -- > hope is the only thing which keeps us all happy > _______________________________________________ > sqlite-users mailing list > sqlite-users@sqlite.org > http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users D.
