The Storage.SQL class contains a set of storage interface methods that use embedded SQL statements, as well as an advanced set of data mapping definition, to provide a way to layer objects on top of pre-existing InterSystems IRIS data structures. More...

The Storage.SQL class contains a set of storage interface methods that use embedded SQL statements, as well as an advanced set of data mapping definition, to provide a way to layer objects on top of pre-existing InterSystems IRIS data structures.
The storage interface methods, which are implemented as method generators, work in conjunction with the persistent interface methods of the <class>Persistent</class> class to provide persistent behavior for objects.
The methods of Storage.SQL are not meant to be called directly. Use the methods of the <class>Persistent</class> class which, in turn, call the appropriate <class>Storage.Persistent</class> method.

DeleteData()
Delete object from persistent storage The caller is responsible for calling IdSet() Don't include class name with id in input parameter
|
staticprivate |
Exists()
Check to see if an OID exists in the extent of this class...

KillExtentData() - kills extent data in storage.
This method is
implemented by the storage class. If killstreams is true (default is false) it will also kill the default stream storage global.
| _.Library.Status LoadData | ( | _.Library.String | id | ) |
Load object from persistent storage into memory.
The caller is responsible for calling IdSet() Don't include class name with id in input parameter
| _.Library.Status SaveData | ( | _.Library.String | id | ) |
SaveData()
Save the object to a persistent state (e.g. store it on disk) return: oid or "" if save fails
|
staticprivate |
Release locks held on an object (identified by the id parameter).
If shared is true then the lock released is a shared lock. If immediate is true then release the lock immediately (lock not held until completion of the current transaction)
