MyBatis AdminMapper SQL Mapping for CRUD Operations and Custom Queries

This is an XML file that defines Mybatis SQL mapping for the AdminMapper interface. It includes SQL statements for CRUD operations and some custom queries for retrieving Admin entities from the database. The file starts with the '<'mapper' element that specifies the namespace for the mapper interface. It then defines a 'resultMap' for mapping query results to Admin objects, a 'Base_Column_List' for reuse in other SQL statements, and various SQL statements for inserting, updating, selecting, and deleting Admin entities from the database. The file also includes custom queries for finding Admin entities by various criteria and retrieving all Admin entities with a specific role.
