sqt::ColumnType Concept Reference

#include <sqt/orm/table/column/column_type.h>

Description

Constrains a type to be a column type.

Requirements

• The type must derive from sqt::AbstractColumn.
• The type must have a nested type EntityType, representing the entity type from which the column is mapped.
• The type must have a nested type ValueType, representing the value type of the column.
• The type must have a nested type ValueTraits, defining traits for the value type.
• The type must have a nested type ValueSource, which must satisfy the sqt::ValueSourceType concept.
• The type must have a static constant Name of type std::string_view.

Columns defined by the SQT_COLUMN_FIELD, SQT_COLUMN_ACCESSOR and SQT_COLUMN_CUSTOM macros satisfy this concept.
