sql - Is there a more efficient way of selecting data from a dynamic table than using a temp table? -


can be a table near me, including different types and fields of many ways, and I have a table definition table which I what data tells which is the area I need to choose things from the table, so currently I have the table definition in the table, and a dynamic select statement by choosing a temporary table Builds Not, then act on it.

The actual amount I am selecting is very large, more than 5 million records. I'm wondering if a floating table is actually the best way to do this.

What are the other more efficient options I need to do?

If your data is static, report - cache is the most popular query result, preferably on the application server. Or multi-dimensional modeling (cubes) are actually "more efficient choices" to do this.

temporary tables, table variables, table data type ... in any case you will be using your tempdb, and if you want to optimize your queries, customize Tempdb storage (after checking) You can also create indexing for your floating tables.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
