SQL Server 2012: FORMAT Function

Using CLR under the covers, we will now finally have relative parity with the .format() function we are used to using in .NET languages like C#. This means we needn’t to memorize codes like 101 and 103 anymore (to convert datetime values to localized presentation formats), or we can easily format the currency values etc.

Examples: Format date with Format Function as:

DECLARE @d DATE = '2012-11-19';
SELECT FORMAT(@d, N'yyyy-MM'),
       FORMAT(@d, N'yyyy-MM-dd'),
       FORMAT(@d, N'yyyy-MMM'),
       FORMAT(@d, N'dddd, MMM dd, yyyy'),
       FORMAT(@d, N'dddd, MMMM dd, yyyy')      

And the result is:

Format currency values as:

DECLARE @m DECIMAL(12,2) = 322311.43;

-- 'en-us' is culuture.
SELECT Display = FORMAT(@m, 'C', 'en-us')

And here is result:

Error 405 : ASP.NET Core Web API PUT and DELETE Methods not allowed

Recently, while working with .Net core API I came across the issue of “Error 405 — Methods not Allowed” After some research, I found out that both GET and POST requests working fine but neither PUT nor DELETE requests working. Another thing is that the PUT and DELETE request was also working fine on my local machine but failed when we host on our Azure server. When I explored the issue on the web it led me to the conclusion that WebDAVModule seems to set PUT and DELETE request methods disabled by default and due to that PUT and DELETE throw 405 errors. To make the PUT and DELETE requests work, we need to override the WebDAVModule setting in web.config file by adding the below settings under “ system.webServer ”. < system.webServer >   < modules runAllManagedModulesForAllRequests = " false " >     < remove name = " WebDAVModule " />   </ modules > </ system.webServer > There may be 2 web.config files in y...

C#: Merging Excel cells with NPOI HSSFWorkbook

In this post we’ll see how to merge the two or more cell with each other while creating the excel sheet using NPOI . Mentioned below is code to merge multiple cells, in this example we are merging first cell to fifth cell of first row (you can adjust row or cell range by passing particular parameters in CellRangeAddress). //Created new Workbook var hwb = new NPOI.HSSF.UserModel. HSSFWorkbook (); //Create worksheet with name. var sheet = hwb.CreateSheet( "new sheet" ); //Create row and cell. var row = sheet.CreateRow(0); var cell = row.CreateCell(0); ; //Set text inside cell cell.SetCellValue( "This is Merged cell" ); cell.CellStyle.WrapText = true ; //define cell range address // parameters: -> first row to last and first cell to last cell var cra = new NPOI.SS.Util. CellRangeAddress (0, 0, 0, 4); //Add merged region to sheet. sheet.AddMergedRegion(cra); Hope this solution helps you J

How to set Swagger as the default start page for API hosted on the Azure web app?

I created an Asp.Net Core 2.x Web API and configured Swagger on it, below is the code added in Configure method under Startup.cs file, for full swagger configuration, check here //Add swagger configuration app.UseSwagger(); app.UseSwaggerUI(c => {     c.SwaggerEndpoint( "../swagger/v1/swagger.json" , "Test API V1" ); }); On my local machine when I run the API it is automatically redirected to the Swagger page. However, when I hosted this API as an Azure web app it is not redirecting directly to the Swagger and to access the swagger, I had to append /swagger in the URL, for example, https://testapi.azurewebsites.net/swagger/ Solution: Set RoutePrefix to string.Empty under app.UseSwaggerUI like below: app.UseSwaggerUI(c => {     c.SwaggerEndpoint( "../swagger/v1/swagger.json" , "Test API V1" );      c.RoutePrefix = string .Empty; // Set Swagger UI at apps root }); And that’s it, now when you b...
