Subject:  * Converted some of the test cases to use SQL::Abstract::Test.
X-Git-Tag: v0.08240~189^2~36
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=9b4591296c196ea0a32e67159e35091b02ecc539;p=dbsrgits%2FDBIx-Class.git

 * Converted some of the test cases to use SQL::Abstract::Test.
 * Added the parens for the join condition (SQL::Abstract::Test can't cope with it, and, besides, they help readability there; plus this gives the same output that older SQLA generated).
