Defines

• #define DB_CAP_ALL   (DB_CAP_QUERY | DB_CAP_INSERT | DB_CAP_DELETE | DB_CAP_UPDATE)

  All database capabilities except raw_query, replace, insert_update and last_inserted_id which should be checked separately when needed.
  

• #define DB_CAPABILITY(dbf, cpv)   (((dbf).cap & (cpv)) == (cpv))

  Returns true if all the capabilities in cpv are supported by module represented by dbf, false otherwise.
  

Typedefs

• typedef enum db_cap db_cap_t

  Represents the capabilities that a database driver supports.
