DocumentDB supports replacing JSON documents using the ReplaceDocumentAsync method of the DocumentClient class. await client.ReplaceDocumentAsync(UriFactory.CreateDocumentUri(databaseName, collectionName, familyName), updatedFamily);

DocumentDB supports deleting JSON documents using the DeleteDocumentAsync method of the DocumentClient class. await client.DeleteDocumentAsync(UriFactory.CreateDocumentUri(databaseName, collectionName, documentName));

Entity Framework (EF) is an object-relational mapper that enables .NET developers to work with relational data using domain-specific objects. It eliminates the need for most of the data-access code that developers usually need to write. Entity Framework allows you to create a model by writing cod...

Note: in the subsequent passages, the terms hash map and hash table are used interchangeably and refer to the same concept, namely, a data structure providing efficient key lookup through use of an internal hash function. Introduction Although R does not provide a native hash table structure, simi...

Like most of the other programming languages, T-SQL also supports IF..ELSE statements. For example in the example below 1 = 1 is the expression, which evaluates to True and the control enters the BEGIN..END block and the Print statement prints the string 'One is equal to One' IF ( 1 = 1) --<-...

We can use multiple IF statement to check multiple expressions totally independent from each other. In the example below, each IF statement's expression is evaluated and if it is true the code inside the BEGIN...END block is executed. In this particular example, the First and Third expressions are ...

In a single IF..ELSE statement, if the expression evaluates to True in the IF statement the control enters the first BEGIN..END block and only the code inside that block gets executed , Else block is simply ignored. On the other hand if the expression evaluates to False the ELSE BEGIN..END block ge...

If we have Multiple IF...ELSE IF statements but we also want also want to execute some piece of code if none of expressions are evaluated to True , then we can simple add a final ELSE block which only gets executed if none of the IF or ELSE IF expressions are evaluated to true. In the example below...

More often than not we need to check multiple expressions and take specific actions based on those expressions. This situation is handled using multiple IF...ELSE IF statements. In this example all the expressions are evaluated from top to bottom. As soon as an expression evaluates to true, the cod...

You can apply formats within a procedure, e.g. to change the groupings within a proc summary or proc freq. Grouping SAS dates data example2 ; do Date = '01JUN2016'dt to '31AUG2016'dt ; Days = 1 ; output ; end ; run ; /* Summarise by year & month */ proc summary data=exampl...

If you know you need a packet <packet>, but you don't know the exact name <packet-exact-name>, instead of searching with Google try with the following: sudo apt-get update apt-cache search <packet> This will return you a list of packets name with a description. Once you have i...

C# Suppose you want to test that when you hover over an element, a drop list is displayed. You may want to check the contents of this list, or perhaps select an option from the list. First create an Action, to hover over the element (e.g. my element has link text "Admin"): Actions mouse...

In this example we create a new list element with the text "new text", and select the first unordered list, and its first list element. let newElement = document.createElement("li"); newElement.innerHTML = "new text"; let parentElement = document.querySelector(&quo...

An element can be removed by calling remove() on it. Alternatively, one can call removeChild() on its parent. removeChild() has better browser support than remove(). element.remove(); element, and all its childnodes, are removed from the DOM. parentElement.removeChild(element); element...

To execute a function within a loop in node.js, it's fine to use a for loop for short loops. But the loop is long, using for loop will increase the time of processing which might cause the node process to hang. In such scenarios, you can use: asycn.times function recursiveAction(n, callback) { ...
