NUMBERS If a system variable was declared as deprecated without mention of an alternative, the message would look funny, e.g. for @@delayed_insert_limit: Warning 1287 '@@delayed_insert_limit' is deprecated and will be removed in MySQL . The message was meant to display the version number, but it's not possible to give one when declaring a system variable. The fix does two things: 1) The definition of the message ER_WARN_DEPRECATED_SYNTAX_NO_REPLACEMENT is changed so that it does not display a version number. I.e. in English the message now reads: Warning 1287 The syntax '@@delayed_insert_limit' is deprecated and will be removed in a future version. 2) The message ER_WARN_DEPRECATED_SYNTAX_WITH_VER is discontinued in favor of ER_WARN_DEPRECATED_SYNTAX for system variables. This change was already done in versions 5.6 and above as part of wl#5265. This part is simply back-ported from the worklog.
