Subject: Raise an error if a term of the form "TABLE.*" appears in the RETURNING clause,
X-Git-Tag: version-3.36.0~279
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0d23f678b1d26a469a801c1e80f46003c55cf2e1;p=thirdparty%2Fsqlite.git

Raise an error if a term of the form "TABLE.*" appears in the RETURNING clause,
as SQLite does not (yet) know how to handle that.
Ticket [132994c8b1063bfb].
