An example of ASP. NET SQL serverinstallation guide (aspnet_regsql.exe)

Try this tool today. First, a database named TESTDB is created in the database, and then a new Login Name (testdb) is created, specifying testdb as the default database of TESTDB. Then the configuration starts.

The configuration process refers to 《aspnet_regsql.exe, but when you select the server and database, enter the correct server name, select SQL server authentication, and enter the new testdb user name and password, click the drop-down box to select the target database. An error message is displayed: (the list of database names in SQL Server cannot be queried. The user's default database cannot be opened, logon fails, and user 'testdb' logon fails)

Oh, by the way, I forgot to authorize this user. This user does not have the logon permission. To ensure that the configuration will not fail due to permission issues, I will grant this user the highest permission for sysadmin. Then run the command again, but the following error is still reported: (the list of database names in SQL Server cannot be queried. The object name 'sysdatabases' is invalid)

This is strange. If I try to use sa, there is no problem. I can display the names of all the databases in the database. Is there still insufficient permissions ?? I know that sysdatabases is a view in the system table and is used to read all database names. So I use testdb to log on to the database and try to execute this command:

Select * from sys. sysdatabases

No problem. The table names can be displayed. This should not be the access permission problem. What should we do?

Solution:With a try attitude, I entered my database name TESTDB in the database drop-down box shown in the figure above, and clicked next. It actually passed ~~~, After the configuration is successful, go to the database and check the 11 tables that are automatically generated starting with asp _ and the attempts and stored procedures.

Conclusion: I don't know where the problem is. Although the problem has not been solved, it is a problem with the configuration tool.
