将数据存储在sql server 2005 asp.net c＃网站中

Question

I have created a project which has internal/in built VS database... now I want to connect it to external SQL server database

How can I do this? Does it affect my project? How about connection string that I created during my inbuilt database?

Answer 1

You can connect to external database by specifying its name and credentials.If it is on your pc than in server give name of your PC.And if you are using sql server authentication than you have to give username and password

server=yourpcname;database=databasename;uid=userid;pwd=***;Pooling=false;

If you are using windown authentication

server=yourpcname;database=databasename;Pooling=false;

Answer 2

Add to web.config in

configuration\\connectionStrings

<add name="SOMECONNECTIONNAME" connectionString="server=SOMEIPORNAME;database=SOMEDATABASENAME;user id=SOMESQLUSER;password=SOMEPASSWORD" providerName="System.Data.SqlClient"/>

Call in code by

SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["SOMECONNECTIONNAME"]);
            connection.Open();
SqlCommand command = new SqlCommand("StoreProcedurename", connection);
                command.CommandType = CommandType.StoredProcedure;
                command.Parameters.AddWithValue("@DateFrom", DBNull.Value);
                command.Parameters.AddWithValue("@DateTo", DBNull.Value);
                SqlDataReader DR = command.ExecuteReader();

etc.

Connect to External database using connection string.

first add the connection string to web configuration file

      <connectionStrings>
      <add name="managementportal" connectionString="Data Source=HSBHV;Initial Catalog=itamma00_HSB;User ID=sa;Password=HSB555" />
    </connectionStrings>

then use the ConfigurationManager in cs page using connection name "managementportal"

      SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["managementportal"].ConnectionString);
