In this post, let me explain about How to List Out SQL Logins and Database User Mappings.

You can use system stored procedure sp_msloginmappings to list out the SQL logins and database user mappings. And here is the syntax:
sp_msloginmappings @Loginname , @Flags

@Loginname – Optional argument, in case if you not specify the Login name procedure will return the result for all the SQL Server logins
@Flags – You can specify value 0 or 1, 0 value will show user mapping to all databases and 1 will show the user mapping to current database only. Default value is 0
use master
go
exec sp_msloginmappings 'sa', 0

use master
go
exec sp_msloginmappings 'sa', 1

If you want to run the sp_msloginmappings across multiple SQL Instance using either Central management server or Powershell, write the following script:
create table #loginmappings( 
 LoginName  nvarchar(128) NULL, 
 DBName     nvarchar(128) NULL, 
 UserName   nvarchar(128) NULL, 
 AliasName  nvarchar(128) NULL
)   
insert into #loginmappings
EXEC master..sp_msloginmappings
select * from #loginmappings
 drop table #loginmappings

Today, I will show you how to upload excel file, read Excel file data,  save Excel file data & import into SQL Server using SQLBULK in ASP.NET.

First step, you must create the excel file. And then create a SQL table in database like the following picture:

Next step, add the code in "Default.aspx"

<asp:FileUpload ID="fupUpload" runat="server" />
<asp:Button ID="btnImport" Font-Bold="true" ForeColor="White"
BackColor="#136671" Height="23px" runat="server" Text="Import Excel Data"
onclick="btnImport_Click" />

Now, write the following code in "Default.aspx.cs"
Add these NameSpace
using System.IO;
using System.Data.OleDb;
using System.Data;

Write the code in Click Event of Import Button:
protected void btnImport_Click(object sender, EventArgs e)
{
 string strFilepPath;
 DataSet ds = new DataSet();
 string strConnection = ConfigurationManager.ConnectionStrings
                          ["connectionString"].ConnectionString;
 if (fupUpload.HasFile)
 {
  try
  {
    FileInfo fi = new FileInfo(fupUpload.PostedFile.FileName);
    string ext = fi.Extension;
    if (ext == ".xls" || ext == ".xlsx")
    {
     string filename = Path.GetFullPath(fupUpload.PostedFile.FileName);
     string DirectoryPath = Server.MapPath("~/UploadExcelFile//");
     strFilepPath = DirectoryPath + fupUpload.FileName;     
     Directory.CreateDirectory(DirectoryPath);
     fupUpload.SaveAs(strFilepPath);  
     string strConn = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source="
                      + strFilepPath + ";Extended Properties=\"Excel 12.0
                      Xml;HDR=YES;IMEX=1\"";
     OleDbConnection conn = new OleDbConnection(strConn);
     conn.Open();    
     OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", conn);
     OleDbDataAdapter da = new OleDbDataAdapter(cmd);
     da.Fill(ds);
     DeleteExcelFile(fupUpload.FileName); // Delete File Log
     SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection,
                                   SqlBulkCopyOptions.KeepIdentity);
     sqlBulk.DestinationTableName = "Table_1";
     sqlBulk.WriteToServer(ds.Tables[0]);
     conn.Close();
     sqlBulk.Close();     
     ScriptManager.RegisterStartupScript(Page, GetType(), "script1", 
        "alert('Excel file successfully imported into DB');", true);
     return;
    }    
    else
    {
      ScriptManager.RegisterStartupScript(Page, GetType(), "script1",  
                    "alert('Please upload excel file only');", true);
     return;
    }
  }  
  catch (Exception ex)
   {
    DeleteExcelFile(fupUpload.FileName);      
    ScriptManager.RegisterStartupScript(Page, GetType(), "script1",  
      "alert('error occured: " + ex.Message.ToString() + "');", true);
    return;
   }
  } 
 else
  {
    ScriptManager.RegisterStartupScript(Page, GetType(), "script1",  
                        "alert('Please upload excel file');", true);
   return;
  }
}
protected void DeleteExcelFile(string Name)
{             
 if (Directory.Exists(Request.PhysicalApplicationPath +  
                                           "UploadExcelFile\\"))
   {     
    string[] logList = Directory.GetFiles(Request.PhysicalApplicationPath
                       + "UploadExcelFile\\", "*.xls");
     foreach (string log in logList)
      {        
        FileInfo logInfo = new FileInfo(log);
        string logInfoName = logInfo.Name.Substring(0, 
                             logInfo.Name.LastIndexOf('.'));
        if (logInfoName.Length >= Name.Length)
         {           
          if (Name.Equals(logInfoName.Substring(0, Name.Length)))
           {
             logInfo.Delete();
           }
         }
      }
   }
}

I hope it works for you! Good luck.

In this tutorial, I will show you how to  to encrypt/decrypt string in SQL Server. First step, you must write the following DB Script:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:        <Author,,Name>
-- Create date: <Create Date,,>
-- Description:   <Description,,>
-- =============================================
ALTER PROCEDURE Enc_Dec
    @username varchar(20),
      @password varchar(10)
AS
BEGIN
      SET NOCOUNT ON;
      DECLARE @encrypt_val VARBINARY(200)
    SELECT @encrypt_val = EncryptByPassPhrase('xxx', @password)
    SELECT @encrypt_val
    INSERT INTO reg_users (username,r_pwd)VALUES(@username ,CONVERT(VARCHAR(200), @encrypt_val, 1))
    SELECT CONVERT(VARCHAR(200),DecryptByPassPhrase('xxx', @encrypt_val ))
END
GO

The output of the above code as shown in the following picture:

In this short tutorial, I will tell you how to self-host the Web API, using OWIN custom host. First step that you must do is Add a new Console application as you can see on the below picture.

Next, in order to make a web API and use OWIN custom host, we tend to add references to Microsoft.AspNet.WebApi.OwinSelfHost, using the Nuget Package Manager. this may not only add the references for the web API however also the OWIN components, along with the opposite needed dependencies.

Add a replacement web API controller class. we tend to take away all the methods and add an easy GET method to get the sum of two random numbers.

Add a new class named Startup.cs. this can be as per the OWIN specifications. Use the HttpConfiguration class to make the web API routing template and add it to the request pipeline using the appBuilder.UseWebApi method, where appBuilder is of type IAppBuilder.

Open the Program.cs file and begin the server using the WebApp.Start method, specifying the StartUp class because the entry point for the settings needed. this is the OWIN specification of starting the server within the custom host.

Now simply run the application and the server is started.

To test the Web API, we’ll use the Chrome browser Postman extension. So type the URL of the Web API that we specified in the Program.cs and Send the request. See the results received as you can see on the following picture:

In this tutorial, let me tell you about How to Fix an Error on Reporting Services “The report server installation is not initialized” ? I had an undertaking for restoring the Reporting Services database from a live situation to a test domain.  Directly after the effective restore, I took  opening the Report Manager site and I was given the error "The report server establishment is not introduced. (rsReportServerNotActivated)". As you can see on the following picture:

SOLUTION

This is a result of the  mismatch in the encryption key. To alter this, either restore the encryption key from the live environment or erase the encryption key from the restored reporting administrations database.  The restoration or cancellation of encryption key could be possible by utilizing the Reporting Services Configuration Manager.

I hope this tutorial works for you!

In this tutorial, I will show you how to handling NULL Character \x00 when Exporting to File Using BCP in SQL Server.

This article talks about the conduct of the BCP utility when removing information from SQL Server to records and all the more particularly to CSV documents. Imagine that you have the underneath table:

As you can see on the above picture, records 2 and 3 contain null values. Now, you need to export the table contents to CSV using BPC: bcp "SELECT [code],[description],[price] FROM [TestDB1].[dbo].[product]" queryout "c:\tmp\testExtract.csv" -c -C 1253 -t ; -S ".\SQL2K14" -T

And here is the output from the code:

As should be obvious on the above screenshot, the output appears to be correct. The records' NULL value have been supplanted with unfilled strings. Now, consider that the first table, rather than NULL qualities has unfilled strings:

Let's try again to export the new table contents to CSV using BPC:
bcp "SELECT [code],[description],[price] FROM [TestDB1].[dbo].[product]" queryout "c:\tmp\testExtract.csv" -c -C 1253 -t ; -S ".\SQL2K14" –T

And here is the output:

As should be obvious, the unfilled strings have been replaced by NULLs which relate to the hexadecimal character \x00. It appears from the above sample, that the queryout keyword has the same behavior regarding null and empty strings.

Presently, if you are going to nourish the CSV document to another application for parsing and handling it, if the application does not expressly handle conceivable events of the NULL character then most probably an error will be occurred. To this end, dependably have as a top priority the above conduct when extracting data to files using BCP.

In this post, I will tell you about rename column name in In SQL Server. Now, I’ve got a table “tblRename” in which there are the two columns Id and Name.

But by mistake I misspelled Name to “Names” and now I want to change the column name to the correct name -> “Name”. So, how is it possible to rename the column name without dropping the table?

We can use a System Stored Procedure sp_rename.
EXEC sp_rename 'tblRename.Names', 'Name','column'

sp_rename is the Stored Procedure.The first value is the tblRename that is the table in which the column is to be renamed, as in "Names" -> tblRename.Names. The second value is the new segment name that we need to change it to, in other words Name. The third value is the sort and here the sort is segment.
Execute the previous query.

Finally, the column name is now changed to Name. But when we execute our query we get an error message:

Along these lines, if there are any Stored Procedures and scripts indicating this tblRename table in which you have determined the "Names" segment then that Stored Procedure or script won't come being used any longer in light of the fact that now there is no section present with a name "Names". In this way, in the event that you need to change the segment name then do it before making any important Stored Procedures or scripts.

Here's a convenient script that is a piece of my tool stash all over I go. Scripts out and identifies basic database level security objects, and creates a TSQL proclamation to reproduce the items. Note that this script just chips away at SQL 2005 or above. This is a long way from an authority script.

This time we will follow a complete and a smart way to create a HTTP server that is exact and quick in Node.js.

Express is insignificant and adaptable Node.JS web application framework that gives a vigorous set of gimmicks of web and portable application. What's more, it will help you in making APIs that verifiably take a shot at the HTTP protocol.

Installation
Express.JS is a framework file hosted by the Node Package Manager (NPM). For installation, we have a special node command to install on the local computer. Write the following code:
npm install [PACKAGE NAME]

And this is code for installing express:
node install express

Note: express is the package name.

After Installing, you will get a folder node_modules that consists of all the modules that you install from npm.

Finally, you have successfully installed the express module in your node folder. Now, write the following code:
// Express
var fs=require("fs");
var host="127.0.0.1";
var port="1337";

//Express
var express=require("express");
var app=express();
app.ger("/",fuction(request, response){
  response.send("Express is Working !!");
});

//Listening Socket
app.listen(port,host);

We utilize the term standard code with express on the grounds that it evacuates the undesirable lines. The code that minimizes the lines of code to do a certain task.  Also, express permits us to make a HTTP server in a couaple of lines of code. And here is the output:

I hope it works for you!
