Subject: add Identity() for remaining examples
X-Git-Tag: rel_2_0_26~31
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a25abbbeb0933d47b61b2614e578cf06b5cb78a1;p=thirdparty%2Fsqlalchemy%2Fsqlalchemy.git

add Identity() for remaining examples

Fixed the performance example scripts in examples/performance to mostly
work with the Oracle database, by adding the :class:`.Identity` construct
to all the tables and allowing primary generation to occur on this backend.
A few of the "raw DBAPI" cases still are not compatible with Oracle.

Change-Id: I7ce19645ea78736dddfda6f33b9356ad75dee68f
(cherry picked from commit 6e0a35dfd8bbd12c999abcae3309fe22e83b0444)
