I'm using Access 2010. Unfortunately, from experimentation, a double
backslash doesn't match a backslash in the data.

I'm actually replacing backslashes with zero-length strings so that I
can determine the number of backslashes in the string based on how
much shorter it becomes. So I need to match a backslash.

Microsoft Access 2010.

I tried all 3 SQL dialects in the help:
let g:sql_type_default = 'sqlanywhere'
let g:sql_type_default = 'sqlinformix'
let g:sql_type_default = 'mysql'
'sqlanywhere' and 'sqlinformix' seem to get around the problem, while
'mysql' does not. Quick googling shattered my misconception that the
latter is a Microsoft invention.
Strictly speaking, the dialect for Access use to be JET, and it is ACE
these days. Because Microsoft Office is so prevalent, I'm surprised
that there isn't a syntax file for that. Ah well, I will run with
'sqlanywhere' until I see anomalies, then switch to 'sqlinformix' to
see if it circumvents them.
Thanks!
