InterBase XE7 Update 1 Overview

InterBase XE7, update 1 went live on Friday and brings with it SQL language enhancements for Change View, and some updates to IBConsole and the availability of InterBase ToGo for XE7

Full details about the update are available on the InterBase DocWiki

Change View Updates

There are 2 major additions to InterBase Change Views in Update 1

Drop Subscription

Prior to update 1 you had to manually drop a subscription via an SQL statement. This was a temporary solution and has now been replaced with the correct SQL syntax

DROP SUBSCRIPTION <subscription name> [RESTRICT | CASCADE]

If you want to remove a subscription that has subscribers you must use the CASCADE command as RESTRICT is the default.

Change View SQL Extensions

InterBase SQL now includes additional language to support querying about the changed state of specific fields via the <FIELD> IS [NOT] {CHANGED | INSERTED | UPDATED | DELETED} clause.

Take the following example.  Lets imagine we have two employee records that have been modified.

  • EMP_NO 39 has their DEPT_NO changed
  • EMP_NO 109 has their SALARY changed.

At run time you want to select only those that have had a SALARY change prior to processing staff payments. To achieve this first, a Change View subscription is set active (making any SQL statement subsequently run only return the delta for that subscriber). Then SQL where clause then filters further where the SALARY IS UPDATED.

SET SUBSCRIPTION sub_employee_changes at 'MyDeviceID' ACTIVE;
SELECT EMP_NO, DEPT_NO, SALARY FROM EMPLOYEE WHERE SALARY IS UPDATED;

EMP_NO     DEPT_NO           SALARY
--------   ----------        ----------
109        600               75000

Regardless of what you select, the commit will still bring
