Detailed Description

Main API for mapping records to and from the database using high level C++ syntax.

A DataMapper instances operates on a single SQL connection and provides methods to create, read, update and delete records in the database.

// Create the record in the database and set the primary key on the record
auto const personId = dm.Create(person);
 
// Query the person record from the database
auto const queriedPerson = dm.Query<Person>(personId)
                             .Where(FieldNameOf<&Person::id>, "=", personId)

Template Parameters

Record	The record type to query and materialize.
QueryOptions	A specialization of DataMapperOptions that controls query behavior, such as whether related records should be auto-loaded. For example, set the relation loading option to false to disable auto-loading of relations when reading a single record.

Parameters

primaryKeys The primary key value(s) identifying the record to load.

Returns: An initialized Record if found; otherwise std::nullopt.

// Example: disable auto-loading of relations when querying a single record
