What is the difference between the name of the registered default instance server and the named inst

1. The difference between the service names in the service:

1) Default instance: mssqlserver;

2) Named instance: the real column name is: benet, and the name in the service is: mssql$benet;

2. The difference when connecting to a query analyzer or profiler:

1) The default instance can be used: ". dot), local, computer name

2) Instance name: computer name: pcname, instance name: benet, and the name used when connecting is: pcname benet

There are a few other differences, but they are sufficient for our normal operation.

The default instance is the one named after the computer on the network. If the application specifies only the computer name when requesting a connection to SQL Server, the SQL Server client component attempts to connect to the default instance of the database engine on that computer. This preserves compatibility with existing SQL Server applications.

There can be only one default instance on a machine, and the default instance can be any version of SQL Server.

Named Instance: An instance that is identified by adding the name of the computer on the network to the name of the instance. That is, after you have a default instance, you need to name the other instances, and you need to name the installed instances again. This is known as a named instance.

Only SQL Server 2000 can be defined as a named instance.

Multi-Instance You can run multiple named instances on a single machine, but only the SQL Server 2000 Database Engine can run as named instances. The database engine in previous versions of SQL Server cannot run as a named instance.

The application connects to the default instance of SQL Server and does not need to upgrade the client connection component of an earlier version of SQL Serve. However, to connect to a named instance, the customer application must use SQL SERVE2000 to connect components, or configure the connection components based on a specific named instance.

One address (IP or machine name) Lives in multiple households (multiple instances).

A server instance is an abstraction of a server.

Multiple instances can be installed on a single server.

Multiple libraries can be installed in one instance.

A server instance is a database! Dizzy.. You can also think of it as the default database is the server instance.

This needs to be determined based on your machine configuration.

and instance servers can be named by yourself.

To query the name of a server instance in SQL Server 2005, perform the following steps:

1. First of all, open the start menu of your computer and select "Control Panel":

2. Next, in the Control Panel tab, select Administrative Tools

3. After that, the service window of the system will be opened

4. In "Services", find the service name that starts with SQL

5. Finally, the "SQL Server (MSSQLSechServer)" service suffix"mssqlserver"is the instance name of the database:

Start Menu, Programs, SQL Server 2005, Configuration Tools, SQL Configuration Manager.

Whether the server name is wrong, you can look at what is behind the "computer name" in the computer properties and copy it to the "logged in server name" and try again, if it still reports an error, it is estimated that your login name and password are wrong.

Look at it this way simply.

In the start menu, under sqlserver configuration manager --sqlserver services--- you see sqlserver().

In parentheses is the instance name.

It is also possible to press upstairs.

in the registry.

hkey_local_machine\software\microsoft\microsoft sql server\installedinstances)

or Service - SQL Server (instance name), the default instance is (MSSQLServ).

Or when connected to Enterprise Management - view the local instance.

in the registry.

hkey_local_machine\software\microsoft\microsoft sql server\installedinstances)

or Service - SQL Server (instance name), the default instance is (MSSQLServ).

Or when connected to Enterprise Management - view the local instance.

This place should be visible, and I don't have an instance installed locally, so I can't see it, and I can't give you a screenshot.

In the past, we could only install one SQL Server on a computer, and it didn't matter if it was an instance problem; Now we can install multiple SQL Server on a single machine, and to distinguish between them, we set the instance name. Each instance is equivalent to a virtual SQL Server server.

To put it simply, if your SQL Server is installed as the default instance, the LAN accesses your database. Only IP+instance name is required.

For example, if it's something else, replace it later.

Similarly, if you have multiple instances on your machine.

If you enter your own database, you need the machine name + instance.

The default word is one" . "That's it.

If you don't default to the machine name and instance name.

SA account. password or Windows authentication.

Simply put, it is to distinguish between multiple instances of SQL Server.

The management studio you run is a management tool (not a sqlserver server), which is used to manage the server, and the new server registration is to connect to a new sqlserver server.

To connect to the native SQLSer service, use (local) or integration authentication.

sqlserver can install multiple independent services (instances) on a single machine, distinguished by different instance names, but generally does not do so, and a single service can generally meet the requirements.

1. Install sqlserver, generally use the default instance name, and add the current user as a database administrator, the installation process will let you set the authentication method (integrated verification or hybrid verification), if your program uses the username and password to connect to SQL, you need to enable hybrid authentication (and need to set the SA password).

2. After the installation is completed (need to be restarted), start Management Studio to connect to the local database service, and you can create a new database and data table after connection (of course, you can also use the program to connect and create with **).

3. When the management studio connects to the server, it is the same as the program connection server, if the connected sqlserver is not the default instance name on the server, the server address needs to have the instance name after the server address (as if: if the instance name is omitted, the default instance name will be connected to the default instance (default instance name mssqlserver).

1. First of all, open the start menu of your computer and select "Control Panel":

2. In the Control Panel tab, select Administrative Tools.

3. Double-click "Service".

4. In "Services", find the service name that starts with SQL

5. The "SQL Server (MSSQLSserver)" service suffix"mssqlserver"is the instance name of the database.

Use the server name or localhost or. . .
