Subject: Support for SET NULL, SET DEFAULT and NO ACTION in foreign key clauses for SQLite.
X-Git-Tag: v0.011017~24
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=565563b9799775b9992c3f7cb85753b1d2b31c39;p=dbsrgits%2FSQL-Translator.git

Support for SET NULL, SET DEFAULT and NO ACTION in foreign key clauses for SQLite.

According to the documentation this should be all of them (with the existing
support of CASCADE and RESTRICT).
