Qore::SQL Namespace Reference

SQL namespace. More...

Classes
class	AbstractDatasource
	This class defines an abstract interface for database access, inherited by both the Datasource and DatasourcePool classes. More...
class	AbstractSQLStatement
	This class defines an abstract interface for the SQLStatement class. More...
class	Datasource
	This class provides the Qore interface to databases. More...
class	DatasourcePool
	Provides transparent per-thread, per-transaction datasource connection pooling. More...
class	SQLStatement
	The SQLStatement class provides the most flexibilty for executing SQL on a database server. More...

Functions
*int	getDBIDriverCapabilities (string driver)
	Returns an integer representing the capabilities of a DBI driver binary-OR'ed together (see DBI Capability Constants) or NOTHING if the driver is not already loaded. More...
nothing	getDBIDriverCapabilities ()
	This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments. More...
*list< string >	getDBIDriverCapabilityList (string driver)
	Returns a list of each capability supported by the given DBI driver (see DBI Capability Constants) or NOTHING if the driver cannot be found. More...
nothing	getDBIDriverCapabilityList ()
	This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments. More...
*list< string >	getDBIDriverList ()
	Returns a list of strings of DBI drivers currently loaded or NOTHING if no drivers are loaded. More...
hash	parseDatasource (string ds)
	Returns a datasource hash of the components of a datasource string. More...
nothing	parseDatasource ()
	This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments. More...
int	dbi_get_driver_capabilities (string driver)
	Returns an integer representing the capabilities of a DBI driver binary-OR'ed together (see DBI Capability Constants) or 0 if the driver is not already loaded. More...
*list< string >	dbi_get_driver_capability_list (string driver)
	Returns a list of each capability supported by the given DBI driver (see DBI Capability Constants) or NOTHING if the driver cannot be found. More...
*list< string >	dbi_get_driver_list ()
	Returns a list of strings of DBI drivers currently loaded or NOTHING if no drivers are loaded. More...
*hash< auto >	dbi_get_driver_options (string driver)
	returns a hash of driver options More...
hash< auto >	parse_datasource (string ds)
