Now requires c++17.
Headline:
Easier, faster, neater: the transaction classes now have a stream
method. You specify a query and the C++ types to which you want
the fields converted, and you get to iterate over the rows. And
thanks to C++14 structured bindings, you can read the fields
straight into separate local variables:
for (auto const [id, name]:
tx.stream<int, std::string_view>("SELECT id, name FROM thing"))
{
process(id, name);
}
For super-fast access to a field's text-format contents, convert
it to std::string_view. It'll give you an immediate reference
to the buffer containing the field. Beware though: the buffer
only holds that text for the one iteration. The next iteration
will overwrite it.

patch-ab no longer needed just since 15 Jan 2018(!)
5 years worth of changes including:

- New exec1(): perform query, expect (and return) a single row of data.
- New exec_n(): perform query, expect exactly n rows of data.
- No longer defines Visual Studio's NOMINMAX in headers.
- Much faster configure script.
- Most configuration items are gone.
- Retired all existing capability flags.

Changes: Lots of bugfixes and compatibility issues addressed.
|
|
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
