The Database Comparer VCL represents 100% Delphi VCL components for Borland Delphi / C++Builder. These components allow you to compare and synchronize SQL database objects and table records for many popular databases. You can view all the differences between databases and execute an automatically generated script to eliminate all or selected only differences. The library includes more than 25 components for Database development and its code is constantly being refined and improved. Delphi / C++Builder 5-7, 2005-2009, RAD Studio 2010, XE-XE8, RAD Studio 10 Seattle and RAD Studio 11 Alexandria support.

Database Comparer helps to compare, synchronize and update databases structure. You can compare one database with another database or database with SQL/DDL script or even two SQL/DDL scripts!

Database Comparer implements highly intelligent and robust synchronization algorithm. During first comparison step it takes Target database or Target SQL/DDL script and compare it to the Master database or Master SQL/DDL script trying to locate all structure differences and prepare final SQL script which will be applied to the Target and make its structure equal to Master structure.

At this stage Database Comparer extracts all objects, descriptions and links from both Master and Target structures and then compares actual objects from Master with objects from Target building final update SQL script. After final update SQL script is ready you can apply it to the Target database if it is available or just save it to the file and run it later.

Database Comparer also support batch mode so you can synchronize list of Target databases with given Master database or SQL/DDL script at one pass.

Features at a glance:

Compare two databases, database and SQL/DDL script, two SQL/DDL scripts
Synchronize data between two database tables

Connect to most popular databases

With Database Comparer VCL components you can compare Oracle, MSSQL, MySQL, InterBase (FireBird, Yaffil), Sybase and Postgre SQL databases. SQL Server 2005 is also supported.

Most popular database libraries such as ADO, BDE, InterBase Express, FIBPlus, IBObjects and ZeosLib supported directly. MyDAC, ODAC and AnyDAC are also supported.

Version 8.1.931.0

New Features
* RAD Studio 12 Athens support was introduced.
* Connecting databases using Universal Data Access Components (UniDAC) was implemented.
* The IBObjects connection support was added.
* A new DB Comparer demo with the UniDAC connection was implemented.
* The implemented GetDbcBuildNo function returns the current build number.
* The Grant/Revoke privileges were implemented for IB/FB stored procedures and functions.
* The "GRANT USAGE ON" statement support for Firebird 3.0 and higher was implemented.
* The new DBExtract.ExtractObjects property allows defining the DB object types to extract.
* Subroutines were excluded from comparing Firebird 3.0 and higher databases.
* A new design-time menu was added to all DBComparer components, including the DBConnection components.
* Please see the Database Comparer VCL Release History page to get full feature and bug listings.

Fixed bugs
* The Table Data Comparer didn't syncrhonize data with different key field names in the source and the target tables - fixed.
* The FireDAC connection component was fixed: added necessary modules to the "uses" section, fixed problems with the "Variable length column [RDB $ FIELD_NAME] overflow".
* The Database Comparer failed to analyze the Firebird CTE syntax, namely CTEs where the "WITH recursive" statement is used - fixed.
* The DBComparer failed to parse the "merge into query" and the "extract (week from...)" statements - fixed.
* The "Column unknown. FNC.RDB$OWNER_NAME" error when extracting Grants in Firebird 2.5 and earlier was fixed.

Known problems and restrictions
* The cross-server support is not yet implemented when comparing and synchronizing the database structures.
* The restricted support for some new features in the most recent versions of databases. And now we are working on it.
