I'm the administrator and simply run the command: sqllocaldb start v11.0 Result: Start of LocalDB instance "v11.0" failed because of the following error: Error occurred during LocalDB instance startup: SQL Server process failed to sta rt. Event viewer log Event ID: 528 > Windows API call WaitForMultipleObjects returned error code: 575. > Windows system error message is: {Application Error} The application > was unable to start correctly (0x%lx). Click OK to close the > application. Reported at line: 3621. I tried another (user and administrator) accounts, there were no problems with them. I uninstalled & reinstalled 2012 version of SQLLocalDB.msi but I had no luck. Do you have any idea & fix?

I keep having trouble with logging into (localdb)\MSSQLLocalDB. It gives the error: > Logon failed for login 'Domain\user' due to trigger execution. > Changed database context to 'master'. > Changed language setting to us_english. When in this state I can't do much diagnostics because I can't log into it. I've been getting out of this with the following shell command.

SqlLocalDb stop MSSQLLocalDB -k
SqlLocalDb delete MSSQLLocalDB

I can then create a new database by logging into the database again, but obviously all data is lost. Trouble is that a few days later the same thing happens again. I'm fairly certain I'm not adding any login triggers. I work on a corporate network and wouldn't be at all surprised if some rogue security tool is doing it. I'm wondering if there is any way of seeing the trigger or capturing diagnostics without being able to login?

I am trying to access LocalDB 2012 on my Windows 7 SP1 PC. I have successfully installed LocalDB and started the instance using the command line, and it is currently running. However, when I attempt to connect to this LocalDB instance using SQL Server Management Studio (SSMS), I receive the following error. > A network-related or instance-specific error occurred while > establishing a connection to SQL Server. The server was not > found or was not accessible. Verify that the instance name > is correct and that SQL Server is configured to allow remote > connections. > (provider: SQL Network Interfaces, error: 26 - > Error Locating Server/Instance Specified) > (.Net SqlClient Data Provider) I have verified the following configurations, and they seem to be working correctly as mentioned in the Link - TCP port is enabled. - SQL Server Configuration Manager is installed. - SQL Browser service is running. - Port 1433 is open. Also note that I have tried connecting using the following instance names, but without success: I have attempted to log in using Windows Authentication. (localdb)\v11.0 (localdb)\mssqllocaldb Given all of this, what could be the cause of the issue.? How can I solve this issue?

I am installing a local instance of SQL Server. During setup the database engine fails. What others steps can make sure the installation succeeds? What I've tried: 1. Installing two times. 2. Repairing installation two times. 3. Turning off firewall. 4. Running installation as admin. 5. The database engine keeps failing. And the SQL Server service fails to start. Am I correct to assume that this fails because the SQL Server service can't start because database engine is not installed? Detailed results: Feature: Master Data Services Status: Passed Feature: Database Engine Services Status: Failed Reason for failure: An error occurred during the setup process of the feature. Next Step: Use the following information to resolve the error, and then try the setup process again.

I downloaded both the LocalDB and Management Studio for MS SQL Server 2014 Express so that I can practice on my local machine. However, when I open Management Studio and try to browse to localDB to connect to start created databases I can't locate the localDB. May someone please assist me with this?

Not really sure if this question belongs here, but I hope someone could help me out. I've made integration tests going all the way down to the database (using mssql localDB). I want each test to run independently with it's own data - I want to reseed the database with my fake data before each test is running. I tried to implement it with transactions without success. Here is how I tried to pull it off: public class TestDbInitializer : DropCreateAlways() { public static List Items; public override Seed(DbContext context) { Items = new List(); // Adding items // .. Items.ForEach(x => context.Add(x)); context.SaveChanges(); } } public class BaseTransactionsTests { private TransactionScope _scope [TestInitialize] public void Initialize() { _scope = new TransactionScope(); } [TestCleanup] public void Cleanup() { _scope.Dispose(); } } [TestClass] public class IntegrationTests : BaseTransactionsTests private IDependenciesContainer _container; public static void AssemblyInit(TestContext context) { Database.SetInitializer(new TestDbInitializer()); _container = new DependenciesContainer(); // Registers all my application's dependencies _container.RegisterAll(); } [TestInitialize] public void Initialize() { using (var context = new MyContext("TestsDatabase")) { context.Initialize(true); } } [TestMethod] public void TestAddItem() { var controller = _container.Resolve(); var result = controller.AddItem(new Item({Name = "Test"})) var goodResult = result as OkNegotiatedResult(); if (result == null) Assert.Fail("Bad result") using (var context = new MyContext("TestsDatabase")) { Assert.AreEqual(context.Items.Count, TestDbInitializer.Items.Count + 1) } } I use my dependency injector in my tests, registering all dependencies once (AssemblyInitialize). I created a DB instance for testings, and a specific DropCreateAlways initializer with a fake data Seed method, which I set as the initializer in the AssemblyInitialize as well. I want to reseed the database with my fake data before each test run. For that case I implemented the base class which holds a transaction scope. When I run my tests, the following exception is thrown when Seeding the database in the TestInitialize: DROP DATABASE statement cannot be used inside a user transaction How should I deal with it? Moreover, what do you think of my implementation of those integration tests? What could be improved?

I cannot connect to a SQL Server 2017 (14.0.1000.169) **Local DB** shared instance. I tried on a laptop that previously had some SQL Server Express and stuff that I all have uninstalled. And also on a fresh Win10 VM. Both always have the same error: >Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Named Pipes Provider: Could not open a connection to SQL Server [2] . . > >Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Login timeout expired. > >Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.. This error is from SQLCMD but I've also tried with SSMS and Visual Studio connection string. I tried connecting with the owner of the instance and could not. Also tried with a SQL Login with *sysadmin* right and could not. **I can only connect with the pipe name.** I also tried everything from: * Why can't I connect to a SQL Server 2012 LocalDB shared instance? on Stack Overflow * SQL 2016 sp1 SQLLocalDB versions errors with "Windows API call "RegGetValueW" returned error code: 0." on MSDN Forums Why can't I connect?

I'm trying to use SQL Server **LocalDb** to store the database by connection string. During first connection to the database I have an error about connecting to the database. In SSMS it is opening. To fix it I need to add **AttachDbFilename** with full path to the **.mdf** file in connection string, despite that I already have **Initial Catalog** property. After first connection I can remove **AttachDbFilename** and then connecting will work also perfectly fine. Reproduces only on the Windows Server OS. On Windows 10 everything works fine. What can be the fix of this issue without adding **AttachDbFilename** during first connection?

I'm trying to deploy a database to a Windows Server machine. The database is a SQL Server LocalDB. When I deploy it to a Windows machine, everything works correctly. When I try to deploy the same database, but to a Windows Server machine, everything is also ok, DB is created, but when I try to work with this database (Get account user data), I got an error: > Unable to update database to match the current model because there are pending changes and automatic migration is disabled. Either write the pending model changes to a code-based migration or enable automatic migration. Set DbMigrationsConfiguration.AutomaticMigrationsEnabled to true to enable automatic migration." I guess changing AutomaticMigrationsEnabled to true is not a solution, as after trying to make it I got the other errors. Also, when I use SQL Server Express Database, everything works without any issues. The issue is only when I use LocalDB together with a Windows Server. Are there any ways to solve this issue?

We have a DevOps pipeline for our DB Build/Release process and we're using VS SQL Database projects. We have one DB which makes extensive use of memory optimized table variables. Used for transfering data to/from a Calc Engine & DB. I know that LocalDB doesn't support FILESTREAM (needed for MO tables), but I'm not looking to nail up a LocalDB. QUESTION: can LocalDB handle DB build/release process for validation purposes? If no, will I need a permanent Azure SQL DB for this purpose?

I am developing a software which requires SQL Server. But for a 50MB application it is not a good idea to tell customers to install SQL Server. So I think it's better to use SQL Server Express LocalDB. I want to give feature of accessing my app from Local Area Network. But I am not getting any related topics to do this. Is it possible to access SQL Server Express LocalDB on Local Area Network? What are the limitations of SQL Server Express LocalDB compared to SQL Server?

I installed Windows 11 on a brand new NUC, then installed all updates. Installed Visual Studio 2022 CE and SSMS (v 18.10) I attempted to start the localDB which is assume was installed as part of Visual Studio 2022/ SSMS and when entering (localdb)\mssqllocaldb in SSMS it get the error  Cannot connect to (localdb)\mssqllocaldb. SQL Network Interfaces, error: 50 - Local Database Runtime error occurred.  Error Number: -1983577846 I then verified/attempted to start the instance as below sqllocaldb stop mssqllocaldb sqllocaldb delete mssqllocaldb sqllocaldb start "MSSQLLocalDB" When typing the last command i received the error  *Start of LocalDB instance "MSSQLLocalDB" failed because of the following error: Cannot create an automatic instance. See the Windows Application event log for error details.* I looked at the log file found under *....\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\MSSQLLocalDB* and see a few error files and select the most latest one by date.

I need to restore a backup for an assignment, but SMSS said I was running v13 while the backup was made in v15. So I downloaded and installed SQL Server Express 2019 and uninstalled the older version. However, SMSS can't connect anymore to (localdb)\MSSQLLocalDB. I read somewhere to add a firewall rule for sqlservr.exe. When I try to run that file manually, it says the SQL Server installation is corrupt. So I ran the Repair from SQL Server Installation Center, everything was okay in the output log but still no luck. I'm pretty clueless, any help is appreciated.

I would like to detect what version of SQL Server Express engine is available so that I can connect either to the (localdb)\v.11 (SQL Server 2012 per https://learn.microsoft.com/en-us/previous-versions/sql/sql-server-2012/hh510202(v=sql.110)?redirectedfrom=MSDN#Anchor_1) or (localdb)\MSSQLLocalDB (SQL Server 2014 and up per https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/sql-server-express-localdb?view=sql-server-ver15&redirectedfrom=MSDN&viewFallbackFrom=sql-server-2014#Anchor_1) instance name when attempting to attach a file in the connection string using the AttachDBFileName= mechanism. I would most likely want to do it from Powershell in some manner, but whatever method is reliable, I can use. I do know that sometimes a LocalDB connection can be a bit slow as it attaches the file and starts up on demand, so I have in the past been pretty lenient on the connect timeout for these LocalDB connections compared to the real SQL Server connections, so I would prefer not trying to connect and waiting for timeout, since I think I've already got an exaggerated timeout just for normal successful connection.

SQL Server 2019 is released but I there doesn't appear to be a LocalDB version available for download. Does anyone know if there will be a LocalDB release or if 2017 is the last version?

I want to install Microsoft SQL Server LocalDB 2017 on my system. I downloaded SQL Server Express Setup (about 5.1 MB). Then I opened it and chose 'Download Media' option and then chose LocalDB. Then it downloaded SqlLocalDB.msi setup (about 45.9 MB). I ran the setup and installed it on my computer. I don't know what to do next. Can someone help me, please?

I get multiple errors with LocalDB (startup error , can't create DB from SQL Server Management Studio and also multiple issues when trying to restore a backup) and none of the fixes I found are helping anything. It seems to me that all errors have their root in permissions not set up correctly. Now a simple DDL table creation script works fine from SQL Server Management Studio and creates the database in the root of my user account's folder (as explained here ). The Instances folder however (located at D:\Users\[My name]\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances despite when installing the SQL Server Express with Advanced Services I specified the DATA folder in another location - where only standard SQL Server Express .mdf files are stored, but not LocalDB instances) seems problematic regarding permissions (in contrary to the account root) therefore and also for having my DB files in a location among my projects I'd like to move the Instances folder to another place. Is this possible? I haven't even found a corresponding registry entry. I'm using SQL Server Express 2012 and also SSMS of the same version (latest updates installed). --- The Database Settings page threw an error for me, not being able to edit nor see any configuration there. I let Windows Update check for updates again and there were some updates for SQL Server Express that weren't installed (although I'm sure I selected everything to install before), so I installed them. This made it possible for me to go to the settings page. I've tried to set up the LocalDB instance's root folder to somewhere else but I get an access denied error for every folder I tried, namely > Alter failed for Settings > 'Microsoft.SqlServer.Management.Smo.ObjectKeyBase'. > (Microsoft.SqlServer.Smo) > > ------------------------------ ADDITIONAL INFORMATION: > > An exception occurred while executing a Transact-SQL statement or > batch. (Microsoft.SqlServer.ConnectionInfo) > > ------------------------------ > > RegCreateKeyEx() returned error 5, 'Access is denied.' (Microsoft SQL > Server, Error: 22002) I get this even if the folder has Full control set for Everyone! Even more amusing the only folder that works, one that is set as a default (the user account's root) has no special permissions applied - just the ones my user has (just as any other folder I tried to set). In effect this means that all my LocalDB databases' files are saved to my account's root folder.

Disclaimer: I am new to MacOs. Haven't found any useful related question. After successfully installing postgresql 13.2 via homebrew on MacOs 11.2.1 (BigSur) i run into the following problem: Use terminal for the command psql postgres Prompts user pwd of my standard Mac user account. Returns: psql: error: FATAL: password authentication failed for user "standarduser" Try: sudo psql postgres Now asks standard user pwd and accepts it. Then asks root user pwd and rejects it with the same error as before: Returns: psql: error: FATAL: password authentication failed for user "root" What am I missing?

I'm working on a desktop app which is installed along with a database, and then connects to the database using SQL Server LocalDB when a user runs the app. The workflow is: 1. When the app starts, it creates and starts a named, user-specific SQL LocalDB instance. 2. When the user chooses a database, the corresponding MDF and LDF files get attached to the instance. 3. The app connects to the database to run queries and get data. A key paradigm in the app is that "a database is just a set of files on disk", much like SQLite or MS Access. So, one should be able to change the files in the database folder, start the app again, and it would work the same, but would now be getting data from the new database. Some database files may be in a central location, so multiple users on the same computer could in theory all have the app open at the same time, pointing to the same database. Luckily, the app does not need to write to the database and there is a "read-only" setting in SQL Server which happens to allow multiple SQL LocalDB instances to all attach and connect to the same database at the same time, as long as they don't write to it. The app can set this by running ALTER DATABASE MyDatabase SET READ_ONLY. The problem is that by default, "auto-close" is on, meaning that when the app disconnects from the instance and reconnects, the database gets set back to read-write mode. A further complication is that when a user logs out and back in again, the SQL LocalDB instance is stopped, and when the app starts it up again, the database *still* gets set back to read-write, *even if auto-close is off*. Is there any way to keep the database in read-only mode and not have SQL Server "forget"? Notes: * I doubt using a shared LocalDB instance would be feasible because of how LocalDB permissions are tied to file system permissions. * The drive to use LocalDB is strong, given that the installation and configuration needs to be as automated and hassle-free as possible. Update: I am going to make the app set the read-only attribute on the MDF and LDF files before it tries to attach them. I think this solves the issue.
