From c11a0e411d62db6f2ad4153579af254081a0e6f0 Mon Sep 17 00:00:00 2001 From: Boris Kolpackov Date: Wed, 26 Oct 2016 16:41:51 +0200 Subject: Implement support for mixed auto/manual id assignment in SQLite Now one can do: #pragma db id auto odb::nullable id; And then set the id to NULL to get auto-assignment or to the actual value to use a manual id. --- sqlite/auto/driver.cxx | 75 ++++++++++++++++++++++++++++++++++ sqlite/auto/makefile | 109 +++++++++++++++++++++++++++++++++++++++++++++++++ sqlite/auto/test.hxx | 33 +++++++++++++++ sqlite/auto/test.std | 0 4 files changed, 217 insertions(+) create mode 100644 sqlite/auto/driver.cxx create mode 100644 sqlite/auto/makefile create mode 100644 sqlite/auto/test.hxx create mode 100644 sqlite/auto/test.std (limited to 'sqlite/auto') diff --git a/sqlite/auto/driver.cxx b/sqlite/auto/driver.cxx new file mode 100644 index 0000000..4841e03 --- /dev/null +++ b/sqlite/auto/driver.cxx @@ -0,0 +1,75 @@ +// file : sqlite/auto/driver.cxx +// copyright : Copyright (c) 2009-2015 Code Synthesis Tools CC +// license : GNU GPL v2;
