版本历史：
Active query builder .net edition 1.5:
  • Ability to define alternate names for database objects and their fields is implemented.
  • The Non-visual mode is added.
  • The new UniversalSyntaxProvider is added to the Free version.
    It is based on the ANSI SQL/92 syntax but allows to determine most of popular database servers, successfully retrieve metadata and apply specific settings for them to let the user build simple queries for these servers.
    Please note that this does not mean that the Universal Syntax Provider could be a suitable replacement for specific database syntax providers, as it strictly follows the rules of ANSI standard, that may lead to many incompatibilities while working with specific database servers. Working with the Standard version, use the Auto Syntax Provider in case of necessity to detect database server automatically.
  • The new UniversalMetadataProvider is added.
    This metadata provider may operate with any valid Connection object, no matter what ADO.NET data provider you use.
    Please note that this metadata provider is unable to retrieve metadata objects from the connection, because implementation of DbConnection.GetSchema() significantly differs for every ADO.NET data provider. Thus you need to use it together with specific syntax providers that are able to retrieve metadata objects via SQL queries. At the moment, UniversalMetadataProvider is operable with DB2, Firebird, Informix, MSSQL, Oracle and PostgreSQL syntax providers only.
  • The new query properties dialog for Oracle is added.
  • Firebird syntax: common table expressions are supported now.
  • Memory and speed optimizations are made.
  • Polish translation is added.
  • Other bugfixes and minor improvements are made.
Active query builder vcl and activex 1.9:
  • Common changes
    • The new Universal Syntax Provider is added to the Free version.
      It is based on the ANSI SQL/92 syntax but allows to determine most of popular database servers, successfully retrieve metadata and apply specific settings for them to let the user build simple queries for these servers.
      Please note that this does not mean that the Universal Syntax Provider could be a suitable replacement for specific database syntax providers, as it strictly follows the rules of ANSI standard, that may lead to many incompatibilities while working with specific database servers. Working with the Standard version, use the Auto Syntax Provider in case of necessity to detect database server automatically.
    • ANSI SQL/92 Syntax Provider has been removed from the Free version.
    • Most of the demo projects are modified to work with Universal Syntax Provider by default.
  • VCL Edition
    • The new way of loading metadata is added to the Event Metadata Provider.
      The new OnloadObjectMetadata event is added to the TacEventMetadataProvider to replace the OnGetSQLFieldNames event. The new event allows you to provide more information about specific database objects, such as stored procedure parameters, etc.
    • The new LoadMetadata demo is added instead of the EventMP demo to illustrate all possible ways of loading metadata.
    • ODBCExpress connectivity package is added (www.odbcexpress.com).
