Cannot connect to SQL Server 2014 from Visual Studio -

-

i have installed sql server 2014 management studio. have imported database .bkp file , try make connection. connection string looks this. 

<connectionstrings>     <add name="name"           connectionstring="server=pcname\sqlexpress;database=databaseinmssql;user id=sa;password=password"           providername="system.data.sqlclient" /> </connectionstrings>

and error:

cannot open database \"databasename\" requested login. login failed.
login failed user 'sa'

here code using connect

public void openconnection() {     if (connection == null)     {         connection = new system.data.sqlclient.sqlconnection(configurationmanager.connectionstrings["name"].connectionstring);     }      if (connection.state != connectionstate.open)     {         connection.open();     } }

i can login windows auth, , sql server authentication in sql server management studio password , user. firewall temporarily off!

i using vs 2013 community edition, , windows 8.1 64bit

it appear user sa (which should never ever use kind of work anyways!) has default database set databasename doesn't exist.

how fix it?

  • login sa or other sql server system admin
  • go object explorer > security > logins > sa , right-click , select properties

enter image description here

  • change default database user does exist
