connection-string

问题 I want to run tests with Effort and to do that I need to specify a connectionstring that also contains a reference to .csdl, .ssdl , and .msl files. The (non-working) connectionstring looks like this now: <add name="SQLAzureConnection" connectionString= "metadata=res://*/Model.projectContext.csdl| res://*/Model.projectContext.ssdl|res://*/Model.projectContext.msl; provider=System.Data.SqlClient; provider connection string="Data Source=(LocalDb)\v11.0;Initial Catalog=Database_Nieuw;Integrated

问题 I've added an alias of "." which should point to my local (named) instance, ".\SQL2008". But when I try to connect to ".", it times out. Am I missing something or is this not allowed? Aliases I've tried which do not work: (Set for both 32 and 64-bit, I've also tried leaving the port blank.) 回答1: If you are creating TCP/IP aliases you need to ensure the "SQL Server Browser" service is running. As well as checking the TCP/IP protocol is enabled for both server and client. In Sql Server

问题 Every SQL Server connection string I ever see looks something like this: Data Source=MyLocalSqlServerInstance;Initial Catalog=My Nifty Database; Integrated Security=SSPI; Do I need the Initial Catalog setting? (Apparently not, since the app I'm working on appears to work without it.) Well, then, what's it for? 回答1: If the user name that is in the connection string has access to more then one database you have to specify the database you want the connection string to connect to. If your user

问题 I'm trying to update the contents of a zip file created from an Excel document. I want to replace some of the content of \zipfile\xl\connections.xml. This partial script will list the contents of the zip file: $shell_app = new-object -com shell.application $zip = “$destination\exceltemplates\Templates\Template1.xlsx.zip” $zip_file=$shell_app.NameSpace($zip) $zip_file.Items() | Select Path But every update method I've tried has generated an error. What's the next step needed to access and

问题 At our workplace, we have an ASP.NET application that uses Microsoft SQL Server 2016 Web Edition Database Server for the back-end database. At first, In the ASP.NET application web.config, I configured the Database Connection String to be: Password=blahPasswordblah; Persist Security Info=True; User ID=sa; Initial Catalog=yadaDatabaseNameyada; Data Source=blahDNSServerNameblah\yadaSQLServerInstanceNameyada It seemed to connect properly. However, I noticed something strange when the code in the

问题 I can invoke psql like this: psql postgres://... How can I use pg_dump with a connection string in the format postgres://... ? Would be more convenient than breaking URI's into host, post, username, password. Is there syntax for this? 回答1: Apparently it's as simple as this: pg_dump postgres://username:password@ec2-00-00-100-100.eu-west-1.compute.amazonaws.com:5432/databasename I just downloaded a dump using this format. Optionally you can add -f filename to specify a local filename. 来源： https

问题 I used the following code to connect C# with database string connStr = "Provider=.NET Framework Data Provider for SQL Server"+ " Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\\Database1.mdf;Integrated Security=True"; try { using (OleDbConnection conn = new OleDbConnection(connStr)) { conn.Open(); if (conn.State == ConnectionState.Open) { using (OleDbCommand cmd = new OleDbCommand(selected_querry, conn)) { cmd.CommandType = CommandType.Text; using (OleDbDataAdapter dAdapter =

问题 I am trying to develop a restful C# service with a connection to Microsoft SQL database. From what I understand, I am supposed to do the connection to the SQL server inside the following code: using System; using System.Collections.Generic; using System.Data.Entity; using System.Linq; using System.Web; using System.Data; using System.Data.SqlClient; namespace Webserver.Models { public class WebserverContext : DbContext { public WebserverContext() : base("name=WebserverContext") { } public

问题 I begin a program by generating a URL object and passing it to create_engine. In a section of code far, far away I would like to find out what this engine is connected to, i.e. the connection URL. Is there an easy way to do this? Using inspect I can only see how to get the driver type. I can understand if the password component of a connection string was no longer available, but I'm hoping everything else is still available. Any ideas? 回答1: This works quite well for me: log.info("* Using DB:
