Constant Detail

DEFERRED

Constant

public static const DEFERRED:String = "deferred"

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

Specifies the deferred locking transaction option. A deferred-lock transaction does not acquire a lock on the database until the database is first accessed. With a deferred transaction, a lock is not acquired until the first read or write operation.

EXCLUSIVE

Constant

public static const EXCLUSIVE:String = "exclusive"

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

Specifies the exclusive locking transaction option. An exclusive-locked transaction acquires a lock on the database immediately. Other SQLStatement objects executing against the same database through a different SQLConnection (in the same AIR application or a different one) can't read data from or write data to the database.

IMMEDIATE

Constant

public static const IMMEDIATE:String = "immediate"

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

Specifies the immediate locking transaction option. An immediate-locked transaction acquires a lock on the database immediately. SQLStatement objects executing against the same database through a different SQLConnection (in the same AIR application or a different one) can read data from the database but can't write data to it. However, for those other connections reading data from the database, the initial state of the data in the database is identical to the state of the database before the in-transaction SQLConnection instance's begin() method was called. Any uncommitted data changes made within the immediate-locked transaction are not available to the other connections.
