If an attempt is made to write, then it is escalated to a write lock. "BEGIN IMMEDIATE" acquires a write lock from the outset and other attempts to obtain a lock will be blocked until the write lock is released (except in WAL mode, in which case a WRITE lock does not block subsequent attempts to READ, which see the database as it existed prior to the WRITE lock being obtained). _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
