Version history

Version History



  • Improved : Support for XMLType data type in Oracle.


  • Fixed : Before generating DROP COLUMN statements in SQL Server, it's now generating DROP CONSTRAINT statements associated to the column.
  • Fixed : "More colors..." option was not working for fill and text color of diagram objects.


  • Improved : Added support for range types in PostgreSQL (daterange, int4range, etc.)


  • Fixed : Firebird 3 did not include data type "Numeric (Identity)"


  • New : PostgreSQL 11 support, avoiding the error "p.proisagg does not exist. perhaps you meant to reference the column p.prolang"


  • Improved : Arguments for OnClassGenerated event now includes references to Table and Sequence attribute. Used in the example Adding Schema Name to Table Attribute.
  • Fixed : Performing project checking in ElevateDB projects now reports wrong field size for char/binary fields with size higher than 1024.


  • New : "Scripting" button in Tools tab in ribbon, opens a full scripting IDE for low-level and advanced manipulation of the existing data dictionary.


  • Improved : List of tables in the Generate Script dialog is now sorted.
  • Fixed : PostgreSQL database importer was not correctly retrieving foreign keys with same name in different tables.
  • Fixed : Fields in primary keys were being nullable when using nullable domains. It broke backward compatibility, fields in primary keys should always be not null.


  • Improved : There is now a check box "Specific" for the "Not null" field. When the field has a domain associated to it, this new check box allows explicitly control if the NOT NULL flag should come from domain or you would want to ignore the domain setting and use a specific value for the field.


  • Fixed : Foreign keys with multiple fields (relationships with composite keys) not being correctly imported from Oracle databases.


  • Fixed : Project window maximizing automatically in some situations.
  • Fixed : Null/NotNull checkbox was disabled for fields associated with logical domains.


  • Fixed : SQL Server ALTER TABLE ADD COLUMN statement was not including constraint name for default values.


  • Fixed : Firebird behavior with domains: size, not null and constraint was not being retrieved from domain.


  • New : Support for Interbase 2017
  • Fixed : Firebird/Interbase connection was not working in some situations
  • Fixed : Error when importing MySQL 8 databases (Table 'mysql.proc' doesn't exist)


  • Fixed : Data Modeler version information in VCL Subscription Manager showing incorrect after automatic update.


  • Fixed : SQLite database import was wrongly considering SQLite "TEXT" datatype as a (char) blob. Now it's considered as regular string (VARCHAR).
  • Fixed : Importing SQLite tables with field names starting with number was raising error.


  • New : Database metadata objects available in customization script events.


  • Fixed : Connecting to MS SQL Server LocalDB was raising an error "SQL Server does not exist or access is denied"
