JDBC local MSSQL Server connection string
I have found my answer from dbeaver support forum.

First enable TCP/IP for your SQL instance in the SQL Server Configuration Manager tool.


Open SSCM and navigate to SQL Server Network Configuration > Protocols for
SQLEXPRESS > TCP/IP
Enable the TCP/IP protocol in the Properties
dialog for TCP/IP. (You can also enable it on the right-click menu.)
Set the TCP/IP port -- which can only be done in the Properties
dialog (i.e., can't do it with just a right-click).  On the "IP
Addresses" tab of that Properties dialog, I used the IPAll settings
at the bottom. Clear out TCP Dynamic Ports, then set TCP Port to
1433.


From within DBeaver, you can create either a jDTS or a "Microsoft Driver" connection

To create a jTDS connection in DBeaver


Create a new connection, specifying MS SQL Server | jTDS driver
Fill out the info on the first (General) tab, complete with User name and Password. I was able to enter my User name as just my Windows user name, not domain\username. But domain\username worked too, and that may be required on some networks. (I'm not sure.)
Go to the "Driver properties" tab and re-specify the DOMAIN and the USER as two separate parameters.
I did not need to re-specify my PASSWORD on the "Driver properties" tab.
And just to emphasize where to enter this: it's entered on the "Driver properties" tab -- not in the dialog box you get to by clicking the "Edit Driver Settings" button that's on the General tab.
Click the "Test Connection..." button to make sure it works, click Next a couple of times, then click Finish.


To create a "Microsoft Driver" connection in DBeaver


Create a new connection, specifying MS SQL Server | Microsoft Driver
Fill out the info on the first (General) tab, without specifying User name and Password (leave them blank).
Go to the Driver properties tab and set integratedSecurity=true.
And, once again, just to emphasize where to enter this: it's entered on the "Driver properties" tab -- not in the dialog box you get to by clicking the "Edit Driver Settings" button that's on the General tab.
Click the "Test Connection..." button to make sure it works, click Next a couple of times, then click Finish.
