| // Package lsql implements a utility wrapper around the database/sql library. |
| // |
| // It simplifies common operations on data entities. An entity type corresponds |
| // to a SQL table, and an instance of the type corresponds to a single row in |
| // the table. |
| // Each entity type must implement the SqlData interface, which specifies the |
| // table schema and mapping of entity instance fields to SQL table columns. |
| // Each entity must have exactly one primary key. More complex relations, such |
| // as foreign key constraints, need to be handled with care (for example, |
| // executing statements in the correct order). |
| // |
| // The library supports creating database tables from the schema, building |
| // query/statement strings for common operations such as SELECT and INSERT, |
| // caching prepared queries keyed by labels and entity types, and transactional |
| // execution. The most common CRUD operations are supported directly by |
| // automatically prepared queries and helper functions. |
