I have been trying in vain to connect to my SQL Server database, attached to the LocalDB instance (localdb)\\v11.0
, using HeidiSql and Windows Authentication.
I realize this question asks about local db; however, this result came up when I was looking around and this answer would have helped me.
In windows search (press enter and type to search) enter "sql server configuration manager". Open that, but make sure you are not opening "sql server master data servervices configuration manager" that is not correct. For me, the first time I had to look be low it in the results under "apps".
Then Click "SQL Server Network Configuration".
If that does not come up, you can manually open the file. See: https://docs.microsoft.com/en-us/sql/relational-databases/sql-server-configuration-manager
For me it is at "C:\Windows\SysWOW64\SQLServerManager13.msc"
Double click "Protocols for [your instance here]"
To access connect using something besides SSMS, you'll need to choose to enable a named pipe, or TCP/IP.
Right Click "TCP/IP" and click properties
Change "Enabled" to true
Change IP4 (or the one with 127.0.0.1 as the IP Address) to be enabled.
Click "Ok".
Jump to restarting
Right click "Named Pipes" and click "Properties"
Change "Enabled" to true
Copy the "Pipe Name" and use that in your database client later
Jump to restarting
As you are warned, you need to restart the service, so click "SQL Server Services" on the left
Right click "SQL Server ([your instance name])" and click "Restart"
You can now use your database client to browse your sql server instance. In heidi, you simply select the network type that matches your setup - choose "Use Windows authentication" and fill in the appripriate hostname/ip (the pipe name or the ip depending on which method you chose to use)
FYI, I answered this question in another SO question as well with step-by-step instructions. Special thanks to @GravityWell for the pipe name suggestion!
It can work, but is tricky. You need to use the LocalDB named pipe as the Heidi hostname. Using LocalDB V12 for example:
sqllocaldb info
sqllocaldb start MSSQLLocalDB
sqllocaldb info MSSQLLocalDB
The "info" parameter reveals:
\\.\pipe\LOCALDB#12345678\tsql\query
Note the number is a random hash, which complicates things, as you need to keep checking it. It's possible to batch/script the above, with Heidi's command line options.
My command line:
heidisql -d=LocalDB -h=%pipename% -n=3 -d=LocalDB
The -d parameter is used twice intentionally.
