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< stringgetDBIDriverCapabilityList (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< stringgetDBIDriverList ()
 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< stringdbi_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< stringdbi_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)
 Returns a datasource hash of the components of a datasource string. More...
