Updating a sequence


To retrieve the next value in the sequence order, you need to use option specifies how many sequence values will be stored in memory for faster access.

The downside of creating a sequence with a cache is that if a system failure occurs, all cached sequence values that have not be used, will be "lost".

One of the most important aspects of the system is the possibility of an integration of data from the database and the ontology.

Upon the synchronization process, the core ontology is cached and populated with the data from the database becoming a synchronized ontology .

If you delete a row in the range, you can also use the fill handle to update the numbers. If you need to update the numbers when you insert the rows, you can create a table for the range.

When you insert a row in the range, the sequence numbers will automatically.

A sequence is an object in Oracle that is used to generate a number sequence.

This can be useful when you need to create a unique number to act as a primary key. The first sequence number that it would use is 1 and each subsequent number would increment by 1 (ie: 2,3,4,...}. If you omit the MAXVALUE option, your sequence will automatically default to: Now that you've created a sequence object to simulate an autonumber field, we'll cover how to retrieve a value from this sequence object.

Although it is possible to have a single installation of the system and synchronizing the ontology at once with all global data, it can result in system overloading and decreasing performance while inferring dependencies.In order to answer these questions either a semantic reasoner is used (which performs classification of concepts within the ontology) or appropriate DL queries are constructed.Based on the definitions of Traffic Danger s in the ontology and information about actual condition occurences, implicit knowledge may be deduced (what kind of danger results from given conditions in a selected area).This results in a "gap" in the assigned sequence values.When the system comes back up, Oracle will cache new numbers from where it left off in the sequence, ignoring the so called "lost" sequence values.Hub account, the actions in the sequence will continue to execute for any currently enrolled contacts.
