Singleton_3


/* Singleton with Private Members, step 3. */
MyNamespace.Singleton = (function() {
// Private members.
var privateAttribute1 = false;
var privateAttribute2 = [1, 2, 3];
function privateMethod1() {
...
}
function privateMethod2(args) {
...
}
return { // Public members.
publicAttribute1: true,
publicAttribute2: 10,
publicMethod1: function() {

},
publicMethod2: function(args) {
...
}
};
})();

Singleton_2


/* Singleton with Private Members, step 1. */
MyNamespace.Singleton = (function() {
return {};
})();

Singleton_1


/* Singleton as an Object Literal. */
MyNamespace.Singleton = {};

You will now use a function, executed immediately, to provide the same thing:

/* Singleton with Private Members, step 1. */
MyNamespace.Singleton = function() {
    return {};
}();

how to analyze table index


analyze table document compute statistics
ex) DOCUMENT Table 만 Analyze
 
analyze index xpkdocbox compute statistics
ex) XPKDOCBOX Index 만 Analyze




select 'analyze table ' || table_name || ' estimate statistics;' from user_tables



select 'analyze index || index_name || estimate statistics;' from user_indexes

Make static class


function foo() {
  var a = 10;
  function bar() {
 a *= 2;
}
bar();
return a;
}
In this example, a is defined in the function foo, but the function bar can access it because
bar is also defined within foo. When bar is executed, it sets a to a times 2. It makes sense that bar
can access a when it is executed within foo, but what if you could execute bar outside of foo?
function foo() {
var a = 10;
function bar() {
a *= 2;
return a;
}
return bar;
}
