Since some databases do not support row value syntax, there exist workarounds to get the same behavior.
JOOQ has implemented those in the following classes:

• https://github.com/jOOQ/jOOQ/blob/master/jOOQ/src/main/java/org/jooq/impl/RowSubqueryCondition.java
• https://github.com/jOOQ/jOOQ/blob/master/jOOQ/src/main/java/org/jooq/impl/RowInCondition.java
