sql server - How can I substitute IDs in a string with corresponding values from a table? -


i've got 2 tables in sql server 2008 r2 database - rules , items

a rules record has id , expression, eg:

  1, "(1 , 2)"

an items record has id , name, eg:

  1, "foo"    2, "bar"

is there way select rule expressions , substitute items ids names in single query?

select magic(expression) rules id = 1

will give me "(foo , bar)"

i'm thinking of doing .net console app, can leverage regex, if there's way in sql, isn't messy, i'd rather go route.

there's thing called clr stored procedure. msdn clr stored procedure

so use regex .net. it's not fast though. simple rule string functions in sql, more complex ones cause serious pain. think i'd tempted outside of sql myself, if there's lot of it.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
