New features in v2025.12.15

"We have been working with the ZDB-Tool Tool for a year now and are very satisfied with it. It speeds up the search considerably and reduces the error rate at the same time. We can only recommend it to everyone. Above all, it is already integrated in Expert, which is surprisingly positive anyway and has to be purchased at a very high price from our competitors. Personally, I can only recommend everyone to take a closer look at this lean and fast search tool :-)"
New features in v2025.12.15
⦁ New feature in the launcher for database optimization. For very large databases, frequent changes, and simultaneous multiple access to the database (i.e., when there is a lot of traffic to and from the ZDB database), it is recommended to call up the new "DB Service" feature from time to time. This optimizes and compresses the entire drawing database. In addition, this function can also restore a corrupt database and speed up general access again.
⦁ Performance improvements.
⦁ Fewer CPU cycles for executing a read transaction.
⦁ Early detection of links that do not return any rows if one or more tables may not contain any rows.
⦁ Avoidance of evaluating scalar subqueries if the result of the subquery does not change the result of the entire expression.
⦁ Faster queries with window functions.
New Functions in v2025.10.09
⦁ Finds associated 2D drawings of a 3D file. This is important if you want to avoid duplicate 2D derivations.
⦁ Various SQLite performance improvements.
⦁ Fixed the aggregate function group_concat() to return an empty string instead of NULL when it receives a single input value that is an empty string.
⦁ The table value function generate_series() has been improved so that it can recognize and use constraints on its output value.
⦁ Fixed two long-known cases of using uninitialized variables under unclear circumstances.

The first import of all Alibre file information may take a little longer depending on the amount of data. This concerns the Launcher-Button:
Start ZDB Importer...
After that, these programm only took a few seconds per run!
