Sometimes you need to import large database into MS SQL Server, but when you use Microsoft SQL Server Management Studio, it doesn't do the job right, but shows the message "Insufficient memory". Or maybe you need to do a batch import of sql script to database instead of doing the import by hand. Here comes in handy the sqlcmd command line tool. It can import large .sql files, can be run from a batch script, installer, etc.
How to use sqlcmd command-line tool to import large .sql file?
Open a command prompt window.
In the Command Prompt window, type: sqlcmd -S yourServer\instanceName -i C:\yourScript.sql
The progress of operation is written to the command prompt window.
