Moved a bunch of things into namespace vendor
...
This namespace is for things the developer will not get in touch with
(normally) but the vendor might need to use for specialization of the
interpreter.
This separation is not fully completed yet, some changes will have to
follow...

Replaced implicit trivial_value_is_null tag for columns with explicit tvin method
...
This isn't database vendor specific, but library vendor specific, as I
used this implicit behaviour quite a lot, but it is utterly confusing
when mixed with prepared statements. Explicit is better here.

Continued to implement standard serializing interpreters
...
Everything that is interpreted also has to move out of detail namespace,
because it might have to be specialized for a database connector
2014-01-11 21:51:57 +01:00
rbock
bef7cea6a6
Started to switch from member serialize -> non-member interpret
...
This will allow database connectors to specialize the interpretation of
the expression tree and interpret queries in vendor specific ways where
required.

Started to use flags to indicate database traits
...
e.g. support for any or outer join, or how string concatenation is
implemented

Stripped a lot of superfluouos type information from result rows.
...
Moved member template into name class to utilize the fact the class
aliases are really just aliases.
This makes the code leaner in many cases and less complex for the compiler
(I guess). It also has the benefit, that the field name is available as
string in the result_rows. This might be useful for debugging one day.

Introduced field template to make result_row_t less specific.
...
It is sufficient to have name and type. There is no need for the result
"to know" what exact expression was used to define the column.
Surprisingly, template alias creates new templates (in contrast to
non-template using, which really just creates an alias of a type).
template<typename T> struct A{};
struct X
{
template<typename T>
using U = A<T>;
};
struct Y
{
template<typename T>
using U = A<T>;
template<>
using U<int> = X;
};
template<template<typename> class X>
struct Z{};
static_assert(std::is_same<X::U<int>, Y::U<int>>::value, "class aliases are really just aliases");
static_assert(not std::is_same<Z<X::U>, Z<Y::U>>::value, "template aliases are new templates");
int main()
