sql server - How to write procedure to get all the data of table of tables? -


i have master table contains table names , columns corresponding table.

i want write procedure iterates through records of tables , gets data , returns single result set.

you need use dynamic query

declare @sql varchar(max)=''  set @sql = (select @sql + 'select ' + column_name + ' '                    + table_name + ' union '               master_table             xml path(''))  select @sql = left(@sql, len(@sql) - 9)  exec (@sql)

note : datatype of columns should same. if not case may have explicit conversion varchar

set @sql = (select @sql + 'select cast(' + column_name + ' varchar(4000)) '                         + table_name                    + ' union '               master_table             xml path(''))

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
