mysql - Limit deleted records when DELETEing w/Using -


i'm normalizing database moving several columns own tables , using foreign keys instead. i'm trying update queries in app use joins possible. in queries delete data, i'd prefer not lookup key values , run delete joins. method i've found works, adding using query - breaks use of limit clause.

delete prism_data using prism_data inner join prism_players p on p.player_id = prism_data.player_id inner join prism_actions on a.action_id = prism_data.action_id (a.action = 'water-flow') limit 5000; <--- ok before using/joins added

i'm trying delete in batches of 5,000. how can modify query limit still valid?

unfortunately, according doc, limit clause valid single table delete:

single-table syntax:

delete [low_priority] [quick] [ignore] tbl_name     [where where_condition]     [order ...]     [limit row_count]

multiple-table syntax:

delete [low_priority] [quick] [ignore]     tbl_name[.*] [, tbl_name[.*]] ...     table_references     [where where_condition]

or:

delete [low_priority] [quick] [ignore]     tbl_name[.*] [, tbl_name[.*]] ...     using table_references     [where where_condition]

http://dev.mysql.com/doc/refman/5.0/en/delete.html

on other hand, sub-queries allowed. maybe refactor query following form?

delete prism_data .... in (select ....) limit 5000

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
