Ah. I'm just ahead. I thought the latest cpan code had the changes merged.
The errors all come from bad SQL being generated. For example this code (from
a Catalyst app)
$items = $c->model('BirdWebDB::SurveyorsSurveySites')->search(
{survey_site_id => $parms->{id} },
{order_by => [{'-'. $sort_order => $sort_column},
{'-asc' => 'name'}],
prefetch => ['surveyor', 'site'],
page => $page,
rows => $limit}
);
Results in this error/sql under version 0.08115:

Under the mssql_limit_regression branch we get this (which works):
SELECT me.id, me.surveyor_id, me.survey_site_id, me.year, surveyor.id,
surveyor.name, surveyor.email, surveyor.phone, surveyor.login,
surveyor.password, surveyor.is_active, surveyor.is_verifier,

site.site_code, site.site_name, site.county, site.location, site.position,
site.elevation, site.comments, site.active FROM ( SELECT * FROM ( SELECT me.*,
ROW_NUMBER() OVER( ORDER BY (SELECT(1)) ) AS rno__row__index FROM (SELECT
me.id, me.surveyor_id, me.survey_site_id, me.year FROM (SELECT TOP 4294967296

site ON site.id = me.survey_site_id WHERE ( survey_site_id = '2' ) ORDER BY

me JOIN surveyors surveyor ON surveyor.id = me.surveyor_id JOIN survey_sites
site ON site.id = me.survey_site_id WHERE ( survey_site_id = '2' ) ORDER BY
year DESC, name ASC:
I'll be patient.
