Databases

Module Description

The Database Classes encapsulate common database objects. All of these classes are contained in the DB Interface Module, and explained in the DB Interface Module User's Guide.

Classes
class	RWDBCheckConstraint
	Represents check constraints, used when creating a database table or fetching a database table schema. More...
class	RWDBCheckConstraintList
	Holds an ordered collection of RWDBCheckConstraint instances. More...
class	RWDBColumn
	Represents a column within a table or schema, or a particular parameter of a stored procedure. More...
class	RWDBConnection
	Represents an explicit database connection object that can be used in place of the implicit database connection provided by RWDBDatabase. More...
class	RWDBDatabase
	Manages connections with database servers. More...
class	RWDBEnvironmentHandle
	Abstract base class from which all vendor-specific environment handles must derive. Environment handles are methods that can set or retrieve certain configuration parameters. More...
class	RWDBForeignKey
	Represents foreign keys in a database, used when creating a database table or fetching a database table schema. More...
class	RWDBForeignKeyList
	Holds an ordered collection of RWDBForeignKey instances. More...
class	RWDBIdentityConstraint
	Represents an identity constraint of a column within a table or schema. More...
class	RWDBManager
	A monostate class that manages RWDBDatabase instances, thus mediating access to database servers. More...
class	RWDBPrimaryKey
	Represents a primary key, used when creating a database table or fetching a database table primary key. More...
class	RWDBSchema
	An ordered collection of RWDBColumn instances, encapsulating the database notion of a schema. More...
class	RWDBStoredProc
	Encapsulates a database stored procedure, providing a uniform API to the common operations related to them. More...
class	RWDBSystemHandle
	Base class for database-specific classes that provide direct access to the database API. More...
class	RWDBTable
	Base class for a family of classes that represent the abstract notion of a database table in a number of different ways. More...
class	RWDBUniqueConstraint
	Represents unique constraints, used when creating a database table or fetching a database table schema. More...
class	RWDBUniqueConstraintList
	Holds an ordered collection of RWDBUniqueConstraint instances. More...
