for_type
. - public unowned DataHandler get_data_handler_default (Connection? cnc, Type type, string dbms_type)
Provides the implementation when the default Libgda's data handlers must be used
- public unowned DataHandler get_data_handler_g_type (Connection? cnc, Type for_type)
Find a DataHandler object to manipulate data of type
for_type
. - public virtual unowned string get_database (Connection cnc)
- public virtual unowned string get_def_dbms_type (Connection cnc, Type g_type)
- public unowned string? get_default_dbms_type (Connection? cnc, Type type)

type
type. - public virtual unowned string get_name ()

cnc
. - public virtual string identifier_quote (Connection cnc, string id, bool for_meta_store, bool force_quotes)
- public unowned SqlParser internal_get_parser ()
This is a factory method to get a unique instance of a SqlParser object for each ServerProvider object Don't unref it.

Performs the operation described by
op
. - public bool perform_operation_default (Connection? cnc, ServerOperation op) throws Error
Performs the operation described by
op
, using the SQL from the rendering of the operation - public virtual string? render_operation (Connection? cnc, ServerOperation op) throws Error

str
for use within an SQL command. - public string value_to_sql_string (Connection? cnc, Value from)
