Query store can be enabled on database by using the following command: ALTER DATABASE tpch SET QUERY_STORE = ON SQL Server/Azure SQL Database will collect information about executed queries and provide information in sys.query_store views: sys.query_store_query sys.query_store_query_text sy...
The following query will return informationa about qeries, their plans and average statistics regarding their duration, CPU time, physical and logical io reads. SELECT Txt.query_text_id, Txt.query_sql_text, Pl.plan_id, avg_duration, avg_cpu_time, avg_physical_io_reads, avg_logica...
If you want to remove some query or query plan from query store, you can use the following commands: EXEC sp_query_store_remove_query 4; EXEC sp_query_store_remove_plan 3; Parameters for these stored procedures are query/plan id retrieved from system views. You can also just remove execution ...
While declaring a function in the $rootscope has it's advantages, we can also declare a $scope function any part of the code that is injected by the $scope service. Controller, for instance. Controller myApp.controller('myController', ['$scope', function($scope){ $scope.myFunction = function ...
ObservableCollection is a collection of type T like List<T> which means that it holds objects of type T. From documentation we read that : ObservableCollectionrepresents a dynamic data collection that provides notifications when items get added, removed, or when the entire list is refres...
files = list.files(pattern="*.csv") data_list = lapply(files, read.table, header = TRUE) This read every file and adds it to a list. Afterwards, if all data.frame have the same structure they can be combined into one big data.frame: df <- do.call(rbind, data_list)
LINQ extension methods on IEnumerable<T> take actual methods1, whether anonymous methods: //C# Func<int,bool> fn = x => x > 3; var list = new List<int>() {1,2,3,4,5,6}; var query = list.Where(fn); 'VB.NET Dim fn = Function(x As Integer) x > 3 Dim list = New List F...
Add the readonly attribute to prevent user input. A readonly field can't be edited <input class="form-control" type="text" placeholder="Readonly input here…" readonly> Add the disabled attribute to disable an input field. A disbled field can't be edited either...
The $http requests require time which varies depending on the server, some may take a few milliseconds, and some may take up to a few seconds. Often the time required to retrieve the data from a request is critical. Assuming the response value is an array of names, consider the following example: ...
$url1 = [uri]::EscapeDataString("http://test.com?test=my value") # url1: http%3A%2F%2Ftest.com%3Ftest%3Dmy%20value $url2 = [uri]::EscapeUriString("http://test.com?test=my value") # url2: http://test.com?test=my%20value # HttpUtility requires at least .NET 1.1 to be instal...
Note: these examples use the variables created in the Quick Start: Encoding section above. # url1: http%3A%2F%2Ftest.com%3Ftest%3Dmy%20value [uri]::UnescapeDataString($url1) # Returns: http://test.com?test=my value # url2: http://test.com?test=my%20value [uri]::UnescapeDataString($url2) # Re...

Encoded with [uri]::EscapeDataString() First, we'll decode the URL and Query String encoded with [uri]::EscapeDataString() in the above example: https://example.vertigion.com/foos? foo2=complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20bar'%22& complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20foo'%22=bar2&am...
