Declare a cursor with the Finder::declare_cursor() method and next get the cursor with get_cursor():
morm::Cursor<MyObject> cursor = finder.
declare_cursor("mycursorname").
select().
raw("ORDER BY column_name ASC").
get_cursor();
The cursor now can be used with fetch.*() methods and then get() or get_list():
MyObject myobject = cursor.fetch_next().get();
std::list<MyObject> myobjects = cursor.fetch_forward_count(10).get_list();
The Finder has get_rows_counter() method which returns how many rows there were
before LIMIT clause was applied. The select(...) method should be called with
Select::with_rows_counter flag in such a case.
while here:
- change the semantic of Finder, now the select(...) method takes a morm::Select flags,
and we have such flags:
- Select::no_auto_generated_columns - do not generate columns from models
- with_rows_counter - add an additional column for the rows counter
- remove Finder::prepare_to_select() - now use select(...) with no_auto_generated_columns flag
those functions can be used with databases and flat files
- removed support for calling static function
- if MORM_HAS_EZC_LIBRARY macro is defined then we can call a function
which has a first argument Ezc::FunInfo<>& object
(only for generating flat files)
FT class has following types:
enum FieldType
{
default_type = 0,
primary_key = 1,
foreign_key = 2,
foreign_key_in_child = 4,
no_insertable = 8,
no_updatable = 16,
no_fetchable = 32, /* not supported yet */
};
an object of FT class are now used in Model::field() methods instead of insertable/updatable/is_primary_key/... boolean flags
changed the semantic of has_foreign_key (which was a bool) flag in child Models:
now on Models and list/vector of Models you should use either FT::foreign_key or FT::foreign_key_in_child
1. FT::foreign_key means that field with this flag is a foreign key and is pointing to the child object
(it was the case when has_foreign_key was equal to true beforehand)
2. FT::foreign_key_in child means that the foreign key is in the child object and is pointing to the parent object
we do not use auto generated 'select' and when we are using prefixes for columns

added BaseExpression::need_to_add_field_prefix()
now the fields() methods don't take add_column_prefix parameter
but the field_name (wchar_t*) is tested whether is it a long (with a period) or short name
added BaseExpression::save_foreign_key() (code moved from field())
removed some default method arguments from BaseExpression
added neq() method for Finder
added DbExpression::prepare_short_table_name(const PT::TextStream & table_name, PT::TextStream & short_table_name)
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1194 e52654a7-88a9-db11-a3e9-0013d4bc506e
(this was for a custom prefix)
- removed column_prefix and column_prefix_index from BaseExpression
now we have a pointer to ModelEnv passed in field() method
- to ModelEnv: added table_name, table_name_simple and table_index
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1193 e52654a7-88a9-db11-a3e9-0013d4bc506e
- added FinderHelper class - used as a global object for the whole model tree in Finder
(some fields moved from ModelData)
- added CursorHelper class - used as a global object for the whole model tree in Cursor
(some fields moved from ModelData)
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1192 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: ModelEnv class - now Model has a pointer to ModelEnv
and ModelEnv has a pointer to ModelData, model_connector_mode, table_index and doc_field_pointer
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1191 e52654a7-88a9-db11-a3e9-0013d4bc506e
(the primary key should consist of only one column at the moment)
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1186 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: using ModelData in BaseExpression so Model::to_text() functions can use a ModelData object now
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1175 e52654a7-88a9-db11-a3e9-0013d4bc506e
model_data points often to a local object (on the stack) so it would be incorrect
to use it in the future
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1131 e52654a7-88a9-db11-a3e9-0013d4bc506e
this allowes us to call query() recursively (from after_select() callback)
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1085 e52654a7-88a9-db11-a3e9-0013d4bc506e
- support for fetching rows from db
- support for inserting/updating rows
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1081 e52654a7-88a9-db11-a3e9-0013d4bc506e
