sql-server - SQL Server LocalDB 错误 ("parent instance invalid")

Question

我安装了 SQL Server 2012 本地数据库 from this download

选择 ENU\x64\SqlLocalDB.MSI

我运行正常，然后尝试使用 sqllocaldb 命令，我得到了这个错误:

PS C:\WINDOWS\system32> sqllocaldb start mssqllocaldb 

Start of LocalDB instance "mssqllocaldb" failed because of the following error:
Unexpected error occurred inside a LocalDB instance API method call.
See the Windows Application event log for error details.

日志是这样说的:

Windows API call RegOpenKeyExW returned error code: 2. Windows system error message is: The system cannot find the file specified. Reported at line: 967.

和

LocalDB parent instance version is invalid: MSSQL12E.LOCALDB

和

Windows API call GetSvcBinPathByInstName returned error code: 2. Windows system error message is: The system cannot find the file specified. Reported at line: 3546.

Answer 1

我通过删除实例并重新创建来修复它:

PS C:\WINDOWS\system32> sqllocaldb delete mssqllocaldb
LocalDB instance "mssqllocaldb" deleted.
PS C:\WINDOWS\system32> sqllocaldb create mssqllocaldb
LocalDB instance "mssqllocaldb" created with version 11.0.
PS C:\WINDOWS\system32> sqllocaldb i
mssqllocaldb
v11.0
