DbSchema 8.4.5

Reverse Engineer using DDL

This feature allows reverse-engineering the schema by parsing the CREATE TABLE DDL statements.
This is available now for MySql, MariaDB, Oracle, Redshift, Snowflake, Sqlite, and Vertica.
Enable this option from the Database Selection Dialog, shown before the Connection Dialog.

The same option can be enabled from ‘Model /Settings / Reverse Engineer’.

Pan and Zoom HTML5 Database Documentation

Zoom the HTML5 diagram vector image using CTRL + mouse wheel and pan (scroll ) by dragging the image using the right mouse button.

Detect Virtual Foreign Keys

When the database does not contain foreign keys, DbSchema can create virtual foreign keys. The virtual foreign keys will be saved in the model file, without creating them in the database.

In the Layout menu, you can find a dialog that will automatically detect virtual foreign keys.
There are two methods to detect them:

• By matching columns by names
• By parsing the SQL statements from the database history cache for SELECT statements with JOINS. The joined columns are used for creating virtual foreign keys.

Matching columns by name is usually searching first for the primary keys, and trying to find other columns and data types in other tables,
with the same name.

Databases like Snowflake have no Primary Keys. In this case, you can disable the ‘Referred Column is Primary Key’ checkbox.

Save Results as JSON

In the SQL Editor Result Pane, there is an option to save the result as JSON.

Other Improvements

• Feature: HTML5 generates documentation using Groovy has one more method in Layout.
• Feature: Improve PDF documentation
• Feature: Introduce wizard in Reports sub-tables
• Feature: The format used in browse and SQL results for numbers is configurable from Model / Settings / DbSchema General
• Feature: Upgrade to JavaFX 17
• Feature: Upgrade MongoDB JDBC Driver libraries
• Bug: Disable column reordering for Sqlite, which creates issues in metatable.
• Bug: Fix issue when refreshing the model and foreign key should be dropped in the database.
• Bug: SQL text indentation issue

DbSchema 8.4.4

Feature: Improve connection dialog

The database selection is done in a separate dialog

In the next dialog we also have a separate combobox for the JDBC Driver and the JDBC URL template.
From the JDBC template combo you can choose also to edit the JDBC URL.
In the next release we will continue to improve the connection dialog.

Feature: Support for Databricks

Databricks is now officially supported in DbSchema.

Feature: Add setting ‘Commit after SELECT’ in Model / Settings / Transaction. Postgres uses AutoCommit off, and this enabled.

We do ‘SET AUTOCOMMIT OFF’ in DbSchema, in order to let users explicit commit the transactions.
If you do, for example, an update and the number of modified rows is higher than expected, you can rollback the transaction.
For Postgres and MySql this may create issues, as SELECT statements are also opening a transaction, which will lock the table.
Therefore, we introduced the ‘Commit after SELECT’ which automatically commits the transaction after an SELECT statement.

Feature: Execute Reports as stand-alone Webserver

Database reports are saved as stand-alone running files .dbsr. They can be started using DbSchema -r

Feature: Improve HTML5 documentation look

We also have upgraded the bootstrap libraries, used in the documentation and Reports

Further Improvements

• Feature: Renew the Windows Code Sign certificate. This caused a decrease of reputation in Windows Defender. Is a matter of time to get the reputation back.
• Bug Fix: Refresh Schema from DB would reverse engineer all tables even if only few were selected
• Bug Fix: Improve the database reports

DbSchema 8.4.3

Introduce Logical Design

DbSchema can do logical design.

You can create entities with attributes and relations, which will map to tables, columns, and foreign keys in the physical model.

The relations can have a logical type.

Inside the layout, you can create different shapes and arrows.

From the menu, you can generate the physical model from the logical model.

Use different converters to map the data types from logical to physical names,
convert the table or column names and the column default values.

The logical design feature is released as a beta feature. We are happy to get feedback from you.

MySql Reverse Engineer the Schema Using SHOW CREATE TABLE

This feature has to be enabled from the Model / Settings / Reverse Engineer dialog.

During reverse engineer, this will deduce the table structure by parsing the output of the SHOW CREATE TABLE command.
This feature is more precise and will load more table parameters compared to the traditional reverse engineer from the database metatables.
For now, this feature has to be enabled manually. Later we will make it the default setting.

Other Features

• Postgres comment on sequences
• Improve SQL auto-completion
• MongoDB reverse engineer relations using DBRef
• Add prepend/append scripts to the schema
• Improvements in data generator and groovy patterns

Bug Fixes

• Hive drop column issue
• Include all tables by foreign key issue
• Crash saving project file when closing DbSchema with ALT-F4
• Improve Views and User Data Type support
• Enable the save project on table color or options change
• Snowflake autoincrement
• Editor tabs cannot be closed or selected

DbSchema 8.4.2

New SQL Parser

DbSchema can deduce the schema structure and diagrams by parsing SQL scripts from the file.

Then you can use DbSchema to document the model, edit it, create new layouts, or deploy it on different databases.

DbSchema 8.4.2 has a new SQL Parser, which is much more flexible. It can parse all database scripts, including Snowflake, SqlServer, Postgres, MySql, Oracle, with partition indexes, sorting, and clustering specifications.

Please write us if you find any statement which is not correctly parsed.

Markdown Database Documentation

DbSchema can export now documentation in Markdown format.

Reports Designer

We redesigned the reports designer.

You have to press the Design button to edit the report. Then you can click any cell to edit or create a component.

We got less feedback about the reports designer, please write us about your experience with it! Together we can make it a very powerful tool.

Other Features

• Feature: Prepare code for implementing Logical Design using DbSchema
• Feature: Sqlite supports renaming columns

• Bug: Postgres drop column cascade
• Bug: Fix Elasticsearch JDBC URL

DbSchema 8.4.1

Implement Mongodb Validation Rules.

Validation rules are used to ensure a collection has a given structure.
All inserts and updates into a collection should match the validation rule.

When creating a new collection or field, DbSchema will also implement the validation rule.
Reverse engineering the schema will deduce the schema from the validation rule, if a validation rule is available.

Please write us about MongoDB features.

Add SqlServer Fulltext Index.

Sometimes, connecting to Snowflake you will see no tables in DbSchema.
In this case you may need to set a role in the connection.
