wish of those help doing multiple rows per transaction, and per query will make it go faster,
when faced with a similar problem I put multiple rows in the values part of the insert query, but you have complicated insert queries, so you'll likely need a different approach.
code :
insert into temptable values ( /* row1 data */ ) ,( /* row2 data */ ) etc...
delete from temptable using livetable where /* .join condition */ ;
delete from temptable where id not in 
  ( select distinct on ( /* unique columns */) id from temptable);
insert into livetable ( /* columns */ )
  select /* columns */ from temptable;

Hope that helps I'd recommend using SQL Server's SSIS functionality to connect to the SQLite database through ODBC/OLEDB, and then import the tables as required.
This is easy to get started - in SQL Server Management Studio, create an empty database - and then right mouse on it, select tasks - and then import/export data. This will get you going as the GUI is easy to use.

may help you . If you're willing to convert the XML to a delimited format of some kind (i.e. CSV), then here are a couple options:
The COPY command in cqlsh. This actually got a big performance boost in a recent version of Cassandra. The cassandra-loader utility. This is a lot more flexible and has a bunch of different options you can tweak depending on the file format.

wish helps you you need to do a select from that ALLFILENAMES table. You can't just specified the tablename + column name like that and expect it to work
also you need to specify the full path in the FROM file name
code :
Declare @sql varchar(max)
select   @sql = isnull(@sql , '')
    + 'BULK INSERT BULKACT FROM ''C:\my_path\CSV Files\' + ALLFILENAMES.subdirectory + ''' '
    + '     WITH ( 
            DATAFILETYPE = ''char'', 
            FIELDTERMINATOR = '','', 
            ROWTERMINATOR = ''\n'', 
            FIRSTROW = 2 
        ); ' + char(13)
from    ALLFILENAMES
print @sql

With these it helps Try using the SQL Server Import and Export Wizard.
Right click on the database in in Object Explorer within SSMS. Go to Tasks > Import Data Select "Flat File Source" for your data source and follow the wizard to specify delimiters, etc.
