Active Query Builder Java Edition v.1.5.0.1100

Below is the list of fixes and improvements in Active Query Builder Java Edition v.1.5.0.1100.

+ The new row controlling toolbar is added to the leftmost column of 
  CriteriaListControl. You can control visibility of this column and it's state 
  by using the is/setRowControllerVisible() and is/setRowControllerExpanded() 
  properties.
+ The check box is added to the Grouping column header. It allows to toggle 
  the grouping for all criteria items at once.
+ The new get/setCreateWhereJoinsByDefault() property is added to all syntax 
  providers. The newly created link conditions will be added to the WHERE clause
  instead of creating of joins in the FROM clause.
+ The new SQLBuilder.BeginBuildSQLForNode, SQLBuilder.EndBuildSQLForNode, 
  BaseSQLBuilder.BeginBuildSQLForNode, BaseSQLBuilder.EndBuildSQLForNode events 
  are added to perform additional processing on building the SQL query text.
+ The new properties are added to LinkOptions property group: 
  get/setAddLinkedObjects(), get/setDeleteUnusedObjects(). The first property 
  instructs the component to add the necessary objects to join the newly added
  object with existing objects. For example, using the Northwind database, 
  by adding Orders and Products tables to the query, the [Order Details] table 
  will be added automatically and joins will be set according to the foreign 
  keys. The DeleteUnusedObjects property instructs the component to remove 
  objects from the query if their fields are not used in the query and these 
  objects are no longer used to link other objects.
+ The new is/setCreateLinksByIdenticalFieldNames() property is added. It may be
  helpful for the databases that does not foreig keys, but suppose to link
  objects in the query by identical field names.
+ The new UnionSubQuery.addLinksFromExpression() method is added.
+ The new methods are added to help iterating through sub-queries in the query:
  QueryBuilder.getSubQueryList(), QueryBuilder.getUnionSubQueryList(), 
  UnionGroup.getUnionSubQueryList().
+ The new GetProcedureParameters event is added to let provide procedure 
  parameter values without showing of the embedded dialog.

Testimonials

We have been using Active Query Builder for over a year and must say that both the product and support have been outstanding!

We chose Active Query Builder due to its flexibility and features, but have been truly pleased by its power and hidden capabilities. ...

In summary Active Query Builder provides excellent components, great support and a very flexible feature set. It has allowed us to provide features to our end users that I did not think would be possible in the first release of our new tools and in a timeframe that was much shorter than planned. I would recommend that anyone dealing with databases in the .Net world should be aware of this component and its capabilities!
