Extended syntax so that it is now possible to set lock_wait_timeout for the following statements: SELECT ... FOR UPDATE [WAIT n|NOWAIT] SELECT ... LOCK IN SHARED MODE [WAIT n|NOWAIT] LOCK TABLE ... [WAIT n|NOWAIT] CREATE ... INDEX ON tbl_name (index_col_name, ...) [WAIT n|NOWAIT] ... ALTER TABLE tbl_name [WAIT n|NOWAIT] ... OPTIMIZE TABLE tbl_name [WAIT n|NOWAIT] DROP INDEX ... [WAIT n|NOWAIT] TRUNCATE TABLE tbl_name [WAIT n|NOWAIT] RENAME TABLE tbl_name [WAIT n|NOWAIT] ... DROP TABLE tbl_name [WAIT n|NOWAIT] ... Valid range of lock_wait_timeout and innodb_lock_wait_timeout was extended so that 0 is acceptable value (means no wait). This is amended AliSQL patch. We prefer Oracle syntax for [WAIT n|NOWAIT] instead of original [WAIT [n]|NO_WAIT].
