What's new in Active Query Builder VCL v1.17

Behavior changes

• The Select checkbox is checked automatically now on adding a new expression.
• Grouping is set automatically now on specifying the aggregate for a column now.
• The numbers entered into condition for string fields are treated as literals.
• The "=TRUE" condition is set automatically on adding a logical expression now. Useful on adding the EXISTS expressions.
• Automatic alias assignment is made when user adds two or more columns with same name to the query. The warning message is shown when muptiple columns with same name appear in sub-queries in result of user actions as this may lead to inconsistence in the calling sub-query.
• The new UserMessage event is added. It is fired when the Query Builder is about to show the warning message to the user. You may override this behavior by handling this event.

SQL Syntax changes

• SQLite: The component can load foreign keys now.
• SQLite: The list of aggregates and built-in functions is filled now.
• MS SQL Server: Fetching metadata object descriptions from database is made.
• MySQL Query Properties form is redesigned.
• MySQL: The SELECT [DISTICT|ALL] options are added to the query properties dialog.

VCL Edition specific changes:

• OLE drag-and-drop of text items to design area and criteria grid is made.

What's new in the Active Query Builder version 1.15?

• General improvements:
  • New feature: Virtual database objects and fields. It allows to hide complex expressions and sub-queries behind ordinary fields and save derived tables as ordinary database objects. See the Virtual Objects And Fields source code sample for demonstration and details. See below to find the corresponding API improvements for VCL and ActiveX Edition.
  • Now it's possible to add Common Table Expressions visually using the context menu item of the query building area.
  • Wheel scrolling in field lists is made.
  • Spanish and russian translations are updated.
• SQL Syntax fixes and improvements:
  • MS SQL Server, Sybase: Support of the old-style TransactSQL outer join operators ("*=" and "*=") is made.

  TacSQLBuilder object will replace all mentions of such fields and objects in result SQL with this expression. Programmer can control such expansion using the TacSQLBuilder.ExpandVirtualFields boolean property.
• The new property TacQueryBuilder.LoadJoinsFromWhereClause: boolean is added. Using this property you can instruct Query Builder to not treat WHERE expressions like "tbl1.FieldName = tbl2.FieldName" as joins. They will be loaded as usual WHERE criteria instead.
• The new property is made to accept tabs in the columns pane.
  TacQueryBuilder.SelectListOptions.AcceptTabs: boolean; default true;
• The new properties are added to the TacQueryBase class to set up the Union operator programmatically:
• UnionOperator: gets/sets the unifying operator ('Union', 'Except', 'Intersect' etc.);
• UnionAllFlag: gets/sets the 'All' keyword for the operator;
• UnionOperatorFull: gets/sets the full operator string (e.g. 'Union All').

Overview

Active Query Builder inclides an SQL parser that correctly handles SQL queries containing multiple nested joins and other detailed points of SQL syntax. Another feature is the graphical engine that allows you to build queries involving unions, nested joins and sub-queries.

The interface of Active Query Builder for Delphi is similar to either MS-Access or SQL Server visual query construction interface.

Active Query Builder supports Oracle, SQL Server, MySQL, PostgreSQL, InterBase, Firebird, SQLite, and ANSI-92 SQL dialects. The sophisticated Active SQL parser can translate any valid SQL statement into it's visual representation. You can use full range of database connectivity components as well as generic event-driven metadata provider to get metadata information from any data source.

The component may be integrated into a Delphi or C++ Builder application with just a few lines of code. Active Query Builder does not force the programmer to use the embedded data grid, SQL editor or anything else. Instead, it allows you to integrate any accompanying tools into your application as quickly and easily as possible. The product is shipped with a detailed help system and a demo application to help you quickly master the product.

Note: Active Query Builder Standard VCL Edition with Source Code is also included in ActiveX Edition with Source Code.
