Constant mariadb_sys::MYSQL_START_TRANS_OPT_WITH_CONS_SNAPSHOT

pub const MYSQL_START_TRANS_OPT_WITH_CONS_SNAPSHOT: uint = 1;

Options for the START TRANSACTION statement.

Note that READ ONLY and READ WRITE are logically mutually exclusive. This is enforced by the parser and depended upon by trans_begin().

We need two flags instead of one in order to differentiate between situation when no READ WRITE/ONLY clause were given and thus transaction is implicitly READ WRITE and the case when READ WRITE clause was used explicitly.
