Synthetic readonly columns
Applies to ❌ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
jOOQ's code generator recognises readonly columns if it is configured to do so. Some databases do not support "real" readonly columns, but allow for emulating them, e.g. through triggers. If a column is a known "readonly column" without formally being one, users can specify regular expressions that match all tables and columns, which will be treated as if they were formal readonly columns. For example:
<configuration>
<generator>
<database>
<syntheticObjects>
<readonlyColumns>
<readonlyColumn>
<!-- Optional regular expression matching all tables that have this identity. -->
<tables>SCHEMA\.TABLE</tables>
<!-- List all columns that are readonly -->
<fields>ID</fields>
</readonlyColumn>
</readonlyColumns>
</syntheticObjects>
</database>
</generator>
</configuration>
See the configuration XSD, standalone code generation, and maven code generation for more details.

As always, when regular expressions are used, they are regular expressions with default flags.
