Dealing with Arrays in SQL and jOOQ

Lukas Eder covers mapping functions:

ARRAY types are a part of the ISO/IEC 9075 SQL standard. The standard specifies how to:

• Construct arrays
• Nest data into arrays (e.g. by means of aggregation or subqueries)
• Unnest data from arrays into tables

But it is very unopinionated when it comes to function support. The ISO/IEC 9075-2:2023(E) 6.47 <array value expression> specifies concatenation of arrays, whereas the 6.48 <array value function> section lists a not extremely useful TRIM_ARRAY function, exclusively (using which you can remove the last N elements of an array, something I have yet to encounter a use-case for)

There are a few database platforms that support the ARRAY type, as Lukas lays out.
