74cafe35dd We now have unique name representations per name 
Before this, there could be multiple classes representing multiple id
columns. Now there is one class representing ALL the name "id". Very
important for analyzing potential name clashes.

rbock
abf4bb8e9a Added serializer to interpreter 
The serializer has partial specializations for all templates. It is a
good basis if the connector/database requires strings close to the
standard.

The interpreter is unspecialized (and uses a static assert to say so).
It is a good basis if the connector/database requires a different
interpretation, e.g. re-writing the expression tree.

The interpretable_t implements three methods for interpretation:
serializing with the sqlpp::serializer_context, serializing with the
database's serialization context and interpretation with the database's
interpretation context.

312e735d6d 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

This separation is not fully completed yet, some changes will have to
follow...

9335a62087 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.

47ae6a2e76 Continued to implement standard serializing interpreters 
Everything that is interpreted also has to move out of detail namespace,

 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

Roland Bock
161da75723 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.
 2013-09-13 09:18:15 +02:00
Roland Bock
2defeff18e 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");

e4bcc27463 is_null() throws for invalid rows 
result_row objects can be constructed with raw result rows representing
