On any connection (as a GdaConnection object), if the database provider used by the connection
supports it, transactions may be started, committed or rolledback, or savepoints added, removed or rolledback.
These operations can be performed using Libgda's API (such as gda_connection_begin_transaction()
), or directly
using some SQL on the connection (usually a "BEGIN;" command). The GdaTransactionStatus's aim is to
make it easy to keep track of all the commands which have been issued on a connection regarding transactions.
One GdaTransactionStatus object is automatically attached to a GdaConnection when a transaction is started, and
is destroyed when the transaction is finished. A pointer to this object can be fetched using
gda_connection_get_transaction_status()
(beware that it should then not be modified). The end user is not
supposed to instantiate GdaTransactionStatus objects
GdaTransactionStatus's attributes are directly accessible using the public members of the object.
struct GdaTransactionStatusEvent { GdaTransactionStatus *trans; GdaTransactionStatusEventType type; union { gchar *svp_name; /* save point name if this event corresponds to a new save point */ gchar *sql; /* SQL to store SQL queries in transactions */ GdaTransactionStatus *sub_trans;/* sub transaction event */ } pl; GdaConnectionEvent *conn_event; };
