Embedded database engine for Borland Delphi and C++Builder. It compiles directly into an .EXE without needing external .DLLs or configuration files.

DBISAM Database System is an embedded database engine for Borland Delphi and C++Builder. It compiles directly into an .EXE without using external .DLLs or configuration files. The footprint is 250-300k (base engine size; does not include data access component layer) and it is available as a transparent single-user, multi-user usage and client/server usage without needing configuration changes. Editions are available with source code.

DBISAM by development environment:

  • DBISAM for Delphi and C++Builder Database Developers: DBISAM compiles directly into your application with no external libraries required. Runtime package support is also provided if so desired. It has a very small footprint and does not require any forms support in Delphi 6 and C++Builder 6 and higher, which helps keep the size of non-UI applications like services or web applications to a minimum.
  • DBISAM for Visual Studio Database Developers: The DBISAM ODBC Driver is contained within a single DLL with no external libraries required. It can be used with Visual Studio 6 using the ODBCDirect access layer and with Visual Studio .Net 2005 or higher with the ODBC.NET Data Provider.
  • DBISAM for Java, C/C++, or Other Database Developers: The DBISAM ODBC Driver is contained within a single DLL with no external libraries required. It can be used with Visual Studio 6 using the ODBCDirect access layer and with Visual Studio .Net 2005 or higher with the ODBC.NET Data Provider.

New Features in Version 4.28 VCL Standard Edition


This release contains the following major enhancement:
  • You can now specify whether indexes should contain statistics or not when creating or altering tables. There is a new parameter for the TDBISAMIndexDef object called NoKeyStatistics, as well as a new clause called NOKEYSTATS for the CREATE TABLE, ALTER TABLE, and CREATE INDEX statements.
  • In addition, this release contains several minor bug fixes and enhancements.

The following is a list of the incident reports addressed in version 4.28 build 2.

  • 2979: Backup and Restore Do Not Work Correctly with a Remote Session When Compiled Under Delphi 2009
  • 3003: Text-Indexed Memo and String Fields Not Working Properly When Compiled Under Delphi 2009
  • 3004: Canned Query Result Sets Not Deleting Temporary Tables Properly
  • 3005: Altering a Table and Adding Two Unique Indexes Can Cause Index Corruption If Duplicate Keys Exist

Features in version 4.21

  • There is a new TDBISAMEngine component that encapsulates the DBISAM engine inside of a visual component
  • The EngineType property can be set to either etClient or etServer in order to have the engine behave as a local client engine or a server engine
  • There are specific events for implementing full text index filtering (either on a buffer basis or on a per-token basis)
  • There are specific events for customising the encryption in DBISAM (8-byte block ciphers only)
  • There is an EngineSignature property in the TDBISAMEngine component that is used to create an MD5 hash that is assigned to every table, table stream, backup, comms request and response. This allows one to "assign" tables to a specific application and prevent any other application from accessing the tables and server without the proper engine signature.
  • All of the ANSI string conversion functions that used to be in the dbisamlb unit are now public methods of the TDBISAMEngine component
  • Large file support can now be switched on and off with the LargeFileSupport property instead of relying on a compile-time DEFINE. Please see the Enabling Large File Support topic for more information
  • The file extensions to use for physical table files, table backup files, and table upgrade backup files can be specified via the following properties: TableDataExtension, TableIndexExtension, TableBlobExtension, TableDataBackupExtension, TableIndexBackupExtension, TableBlobBackupExtension, TableDataUpgradeExtension, TableIndexUpgradeExtension, TableBlobUpgradeExtension
  • Users can now define trigger event handlers that allow for processing both before and after the execution of an insert, update, or delete operation
  • You can now use restricted transactions on a given database where only certain tables that you specify are involved in the transaction
  • There is a new TDBISAMEngine FilterRecordCounts property that controls how record counts are returned for filtered datasets and live query result sets. The default value of this property is True, which indicates that record counts under these circumstances will be returned in the same fashion as they were in 3.x and earlier. If the FilterRecordCounts property is set to False, the RecordCount property of the TDBISAMTable and TDBISAMQuery components will always show the total record count of the entire dataset or active range (if a range is set) only and will not take any active filters (or WHERE clauses with live query result sets) into account. To get the record count including any active filters, a FilterRecordCount property has been added to the TDBISAMTable and TDBISAMQuery components that always shows the accurate record count, regardless of the current setting of the TDBISAMEngine FilterRecordCounts propety.
  • The TDBISAMSession component now has new remote administrative methods for adding/updating/deleting server-side procedures and events
  • The TDBISAMSession component now has the ability to ping a database server using the RemotePing and RemotePingInterval properties. These properties eliminate the need for user-constructed pinging operations using timers and are safe to use for the purpose of shortening dead session expiration times that are configured on a database server and eliminating dangling pessimistic locks when client workstations go down while connected
  • The TDBISAMSession component now has the capability to call a server-side procedure on a database server using the CallRemoteProcedure method, the RemoteParams property and the RemoteParamByName method
  • There is a new TableSize property for the TDBISAMTable component that reflects the total size (in bytes) of the physical table on disk (or in-memory if an in-memory table)
  • The SQL engine can now use the numeric 1 (or anything not 0) and 0 to represent TRUE and FALSE, respectively. This is helpful for compatibility with generic front ends, such as those used with the ODBC driver
  • There is a new TDBISAMQuery OnQueryError event that can be used to trap SQL errors and decide whether to abort an executing SQL statement or not. If an OnQueryError event handler is not assigned, then any SQL errors will immediately surface as an EDBISAMEngineError exception in the TDBISAMQuery component.
  • The TDBISAMQuery component now surfaces the OnAlterProgress, OnDataLost, OnIndexProgress, OnOptimizeProgress, OnRepairLog, OnRepairProgress, OnUpgradeLog, OnUpgradeProgress, OnVerifyLog, and OnVerifyProgress events just like the TDBISAMTable component. The only difference is these events are triggered when the corresponding SQL statement is executed instead of being triggered by a method call, including situations where an SQL statement is executed within a script.
  • There are new OnLoadFromStreamProgress and OnSaveToStreamProgress events in the TDBISAMTable and TDBISAMQuery components for tracking the loading/saving progress of streams.

Version 4.26 release supercedes the 4.25 release. As of the 4.22 release, Borland Developer Studio 2006 support is now included (Win32 only).
