Hi, Your use-case is covered by the model API, much better than the DSL API. More info here: https://www.jooq.org/doc/latest/manual/sql-building/sql-statements/dsl-and-non-dsl
It's also what the DSL delegates all calls to, internally. Hope this helps, Lukas 2017-10-30 16:36 GMT+01:00 <[email protected]>: > Suppose I have a decomposed query in some format, like "fields=a,b,c; > whereClause='1=1'; groupBy=b,c;" etc. Some parts of the query might be > missing, which corresponds to missing SQL part (e.g. a select without where > clause).
