) const

◆ create_primary_key()

◆ drop()

template<bool use_pfs>
template bool dd::Weak_object_impl_< use_pfs >::drop ( Open_dictionary_tables_ctx otx) const

Drop the DD object from DD table.

Parameters
otx- DD transaction in use.
Returns
true - on failure and error is reported.
false - on success.

Drop collections and then drop the object

We should drop collections first and then parent object as we have referential constraints. Mostly the reverse order of restore/store operation.

◆ drop_children()

◆ fix_has_new_primary_key()

template<bool use_pfs>
virtual void dd::Weak_object_impl_< use_pfs >::fix_has_new_primary_key ( )
inlineprotectedvirtual

Reimplemented in dd::Entity_object_impl.

◆ has_new_primary_key()

template<bool use_pfs>
virtual bool dd::Weak_object_impl_< use_pfs >::has_new_primary_key ( ) const
pure virtual

Indicates that object is guaranteed to have primary key value which doesn't exist in database (e.g.

because it only will be generated using auto-increment at store() time). So it is ok for store() method to skip lookup of existing object with the same primary key and simply try to insert new object into the table.

Implemented in dd::Column_type_element_impl, dd::Entity_object_impl, dd::Foreign_key_element_impl, dd::Index_element_impl, dd::Index_stat_impl, dd::Parameter_type_element_impl, dd::Partition_index_impl, dd::Partition_value_impl, dd::Table_stat_impl, dd::Tablespace_file_impl, dd::View_routine_impl, and dd::View_table_impl.
