sql - Syntax for user defined composite type literal -


i have udts (user defined types) in code (postgresql 9.2)

create type pairs_t (keyname varchar, e_value varchar); create type values_t (e_values varchar[]); create type allvalues_t (regions values_t, products pairs_t);

and used in:

create or replace function foo( in _x allvalues_t[] ) returns void $$ begin...

the actual udts in application more complex.

but cannot figure out how type test case. e.g., if wanted (a,prod-a),(b,prod-b) products , () regions, how select * foo(...) statement in pgadmin sql window like? should ... be?

i appreciate if post guide or page describes syntax. have looked @ postgresql man pages no luck.

check out create type in manual.

your example defines type allvalues_t, later uses allvalues. values_t -> value_t. looks simple typos. can't sloppy if want right.

syntax of composite type:

select * foo(('{"(\"(\"\"{arr_a,arr_b}\"\")\",\"(foo,bar)\")","(\"(\"\"{arr_a,arr_b}\"\")\",\"(foo,bar)\")"}'))

how can find out yourself?

create temp table pairs_t (keyname varchar, e_value varchar); -- or create type more permanent solution.  insert pairs_t values ('foo', 'bar');  create temp table values_t (e_values varchar[]); insert values_t values ('{arr_a, arr_b}');   create temp table allvalues_t (regions values_t, products pairs_t); insert allvalues_t values((select x values_t x), (select x pairs_t x));  create temp table test (t allvalues_t[]); insert test values (array[(select x allvalues_t x), (select x allvalues_t x)]);  select * test select x allvalues_t x;

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
