DBISAM 4.46 Released

---

Posted by Tim Young on Thu, Nov 29 2018

DBISAM 4.46 is now available for download. If you're an existing customer, then you should be receiving an email shortly with download instructions.

The breaking changes and new features for both the DBISAM VCL and ODBC products are below.

4.46 New Features

---

The following are the new features in 4.46:

• The join execution performance has been improved, and you should see an overall decrease in execution times for SQL statements that include joins.



• The DBISAM Database Servers that are shipped with DBISAM now include the ability to use SQL performance tracking/logging to detect SQL statements that are exhibiting bad performance. This capability is a server-level feature, and is not implemented in the TDBISAMEngine component (it uses the SQL execution trigger in the engine). You can find out more information on the various dbsrvr.ini file options for the SQL performance tracking/logging here:
  
  Configuring and Starting the Server
  
  under the section that shows a sample dbsrvr.ini file (Sample DBISAM Database Server Parameters INI File).

Embarcadero RAD Studio 10.3 Support Coming Soon

---

Posted by Tim Young on Mon, Nov 26 2018

We are working on Embarcadero RAD Studio 10.3 support for DBISAM, ElevateDB, and Elevate Web Builder (web server modules), and should have the support ready by the end of next week (first week of December). Some further important points about RAD Studio 10.3:

• ElevateDB 2.29 was just released today, but does not include RAD Studio 10.3 support. ElevateDB 2.29 was already in the pipeline when 10.3 was released, so we didn't want to hold up 2.29 any longer since it was already a few weeks later than we wanted, and we wanted to get the new ElevateDB MacOS support released.



• For both ElevateDB and DBISAM, the RAD Studio 10.3 support will also coincide with the removal of the user interfaces for the database servers. This has been a long time coming and will be a prerequisite for releasing Linux daemon versions of both the ElevateDB Server and DBISAM Database Server. The built-in user interfaces will be replaced with GUI utilities that allow you to remotely monitor and configure the servers. This support is already present for the DBISAM Database Server, and will be added for the ElevateDB Server.



• Elevate Web Builder 3 is getting close and will also have its web server UI removed. We are not sure if the initial Elevate Web Builder 3 will have Linux web server support, and it all depends upon how fast we can get OpenSSL integrated into the web server (the Windows version uses the native Windows TLS/crypto API).



• For all other platforms, including mobile and 64-bit MacOS, we will be releasing support for these platforms as Embarcadero transitions those compilers from using ARC to using manual memory management. For more information on this, please see this blog post by Delphi product manager Marco Cantu:
  
  Directions for ARC Memory Management in Delphi

If you have any questions regarding the product platform support, please feel free to ask in the comments section.

ElevateDB 2.29 Released with 32-bit MacOS Support

---

Posted by Tim Young on Mon, Nov 26 2018

ElevateDB 2.29 is now available for download. If you're an existing customer, then you should be receiving an email shortly with download instructions.

The breaking changes and new features for the ElevateDB VCL/LCL, DAC, and PHP products are below. In addition, this release contains several bug fixes, which are detailed here.

2.29 Breaking Changes

---

The following are breaking changes in 2.29:

• The MIGRATE DATABASE statement now disables all default column value assignments when migrating table rows. The migration functionality uses INSERT statements to migrate rows from the source database to the target database. Previously, the default column value assignments could cause primary and unique key conflicts when columns containing NULL values were migrated to the new database.



• The lightweight word generator module, text filter module, and external module templates have been changed so that only module-relevant code is required in the actual project, and all ElevateDB module-specific code is part of engine-level units, similarly to the non-lightweight modules. The following is the implementation code for the new lightweight external module template project's main unit (Unit1):
  
  

  implementation
  
  procedure TEDBLightweightExternalModule1.DoRoutine(const RoutineName: String);
  begin
     { Fill in the routine (function or procedure) execution code here.
       You can have multiple functions and/or procedures in a module.
       Use the RoutineName parameter to determine which function or
       procedure is being executed.  Use the public ParamValues property of
       this external module (TEDBParamValues object) to access the parameters to
       the function or procedure.  Do not modify the ParamValues property other
       than to get/set the parameter values or Null flag.  Adding, removing,
       or changing the data type or parameter type of a parameter can cause
       serious problems.
  
       NOTE: The TEDBParamValues class is an internal ElevateDB engine class,
       and is used instead of the normal TParams class to bypass the inclusion
       of the Delphi VCL/DB units that cause the DLL size to bloat.  You can find
       out the various properties and methods available for this class in the
       edbvalue.pas and edbparam.pas units for ElevateDB.  If you are not
       comfortable working with an internal class such as this that contains no
       documentation, then you should use the normal external module template
       project that is installed into the Delphi object repository }
  end;
  
  initialization
     {  You *must* set the external module class, otherwise your class
        will not get instantiated !!! }
     LightweightExternalModuleClass:=TEDBLightweightExternalModule1;
  end.

  
  The key is the use of the initialization section to assign the class type for all lightweight modules that are instantiated by ElevateDB for this lightweight module.



• For both the normal and lightweight word generator, text filter, and external module template projects, the exports clause has been moved from the .dpr (project file) to the main unit for the template projects. This change was required due to the Delphi MacOS compiler requirement that any library exports clauses not appear in the project files. You will need to make sure to adjust any existing word generator, text filter, and external module projects accordingly if you plan on using them with the MacOS version of ElevateDB.

2.29 New Features

---

The following are the new features in 2.29:

• ElevateDB now supports the 32-bit MacOS compiler for RAD Studio XE4 and higher. RAD Studio XE2 and XE3 lack some necessary platform APIs, so support for those compilers will not be possible.



• ElevateDB now includes SQL statement performance logging that can be used for determining which SQL statements are taking the longest to execute. There are new ENABLE STATEMENT LOGGING and DISABLE STATEMENT LOGGING statements, along with a new LoggedStatements Table system information table for reviewing which statements have been logged.



• The PUBLISH DATABASE statement now includes a new BY clause that allows you to specify how you want the updates for a given table or tables to be logged.



• The MIGRATE DATABASE statement now includes a new START AT TABLE clause that allows you to specify the table at which the migration should start. This is useful when the migration of a large database fails for an unexpected reason, and you don't want to start the migration from the first table in the database again.



• The LOAD UPDATES statement now includes new MERGE DUPLICATE INSERTS and INSERT MISSING UPDATES clauses which allow for further control over how primary key constraints are handled during the loading of updates.



• There are new ENABLE DEFAULTS, DISABLE DEFAULTS, ENABLE GENERATED, and DISABLE GENERATED statements that allow you to selectively enable/disable the default column value and generated column value functionality, respectively, in ElevateDB.



• The join performance in ElevateDB has been improved, especially for SELECT statements that include joins performing lookups. Such joins tend to include lots of repeating driver table values, and ElevateDB uses this information to cache prior join projection sets and avoid re-building them.



• There are new SET STATEMENT CACHE and SET PROCEDURE CACHE statements for setting the statement and function/procedure cache sizes for jobs.
