Executes a file containing CQL statements.
SOURCE 'file'
To execute the contents of a file, specify the path of the file relative to the current directory. Enclose the file name in single quotation marks. The shorthand notation in this example is supported for referring to $HOME:
SOURCE '~/mydir/myfile.txt';
The output for each statement, if there is any, appears in turn, including any error messages. Errors do not abort execution of the file.
Alternatively, use the --file option to execute a file while starting CQL.
