New syntax available for 4D Tags!
A powerful new syntax is available for 4D tags inside texts and Blobs to be processed.
This new syntax is supported in two cases:
- files with “.shtml” extensions served by 4D Web Server
- Text and Blobs sent as parameters to the PROCESS 4D TAGS command
The new syntax is available for three tags, 4DEVAL, 4DTEXT and 4DHTML, which can now be written prefixed with a $ (dollar sign) rather than as HTML comments.
New parameter for DISTINCT VALUE
With 4D v15 R4, a new parameter is introduced for the DISTINCT VALUE command. This parameter must be an array, and it receives the count of each distinct value in a selection of records.
This feature is particularly useful for obtaining statistics on records, or to order records by their most common type.
JSON export for Journal
In 4D applications, the data file is important, so all the activity of the database is stored in the log file. As you all know, the log file is a vital element for the restoration of your database following an unfortunate contingency. However all the information on the database activity may also be useful for analysis. For example, to check the activity on a table, to see the changes made by a user, and to follow a record’s history.
Suspend and Resume transaction
This feature is useful when you need to perform, from within a transaction, certain operations that do not need to be executed under the control of this transaction.
More control on GRAPH command
The GRAPH command has been totally refactored to ease the use and customization of your graphs. Moreover it has been enhanced to give you the full control on the various graph properties.
