15e8ca742c A step towards turning select into a really variadic template 2014-05-19 22:54:47 +02:00
rbock
569f0ff2eb Wrote down remaining steps for next release 2014-05-19 08:01:14 +02:00

bfd13c6743 Determining column_list in a more generic way. 
By finding the last parameter which is a return value.
 2014-05-19 07:51:24 +02:00
rbock
e39444b0f7 Added tags missing and return_value 
missing indicates that a statement part has yet to be added (e.g.
columns in a select).

return_value indicates that a statement part can be used as a return
value.

1d905e1db5 Ok, the first few lines of test code compile again. 2014-05-15 23:47:16 +02:00
rbock
d062c1a0d8 Started to rewrite traits and recursive traits 
traits are shorter and easier to identify by using tags in a variadic
template

recursive traits can be automatically derived, which makes it much
easier to add new traits to be handed through the expression tree.

57239d10ed Rewrote result_row implementation to be non-recursive 
Cool. This is so much easier to understand now!
 2014-05-07 23:56:12 +02:00
rbock
bcdcf7fa64 Added column_index_sequence 
This is not necessarily sequential because there might be multi_columns.

the fastest implementation around :-)

With this method you can indicate additional tables that might be added

1824f9cde0 Changed NULL handling in results. 
If the column or the connector indicates that NULL corresponds to a
trivial value, then the trivial value is returned. Otherwise, an
assert fails or an exception is thrown, depending on the preferences of
the connector.

rbock
3bbe343a77 Added a better MockDb that can execute statements 
Currently all executions are no-ops, but it will be rather simple to
yield select results too (to be configured at runtime).

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.

61a4797d0b Simplified syntax for multi_columns a lot 
Instead of

multi_column(alias, columns...)

it is now

Also, you can now write:

all_of(table).as(alias)

A lot of sweating to figure out how to do it, but now it looks MUCH

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
interpreter.

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

The Db parameter would actually have prevented different Context
overloads (or made more difficult than necessary).

47ae6a2e76 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.

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.

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");
