I am using gvim on windows and have a file with several lines that look like this

Select '305','TableA
Select '313','TableB
Select '313','TableC

I would like to append the following line at the end of each line. 

', count(*) from [Tablename] where msgid in (select msgid from mainTable where row_dtm<'17NOV11')

The result should look something like this (Note that the [TableName] is replaced by the actual table name.

Select '305','TableA', count(*) from TableA where msgid in (select msgid from mainTable where row_dtm<'17NOV11')
Select '313','TableB', count(*) from TableB where msgid in (select msgid from mainTable where row_dtm<'17NOV11')
Select '313','TableC', count(*) from TableC where msgid in (select msgid from mainTable where row_dtm<'17NOV11')

I can add append the text at the end by just doing 

%s/$/', count(*) from [Tablename] where msgid in (select msgid from mainTable where row_dtm<'17NOV11')/g

But i am stuck as to how i can read the table name and put that in place of [Tablename].

Basically i am just trying to generate several queries. Any ideas?
I know that the table name will always be the text from the end of the line to the first ‘ character but how do i read it and add it to the modified string?

Thanks

    You need to do a tiny bit of back referencing.
    Change the search term to:
    \(\a\+\)$ this will match the table name. Surrounding the search term with \( and \) allow it to be referenced in the replace
    Add \1 to your replacement string wherever you want the tablename to appear.
    The result should look like this
    %s/\(\a\+\)$/\1', count(*) from [\1] where msgid in (select msgid from mainTable where row_dtm<'17NOV11')/g
