Subject: Rework the code that computes the datatypes and affinities for subqueries
X-Git-Tag: version-3.41.0~246
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=daa46142ecf8dd3b886fb5940e1faf4366a36df3;p=thirdparty%2Fsqlite.git

Rework the code that computes the datatypes and affinities for subqueries
and views.  If the subquery/view is constructed from a compound SELECT where
the affinity varies across arms of the compound, set the affinity for the
corresponding column in the constructed view to be BLOB so that it is allowed
to take on any data type.
