How to convert Sql orderby clause with Case Statement into JOOQ?

问题

I want to convert Sql orderby clause with Case using JOOQ.and BillAmount is of BigDecimal datatype.

 ORDER BY CASE WHEN (BillAmount <= 0) 
THEN
 BillAmount 
ELSE
 BillNumber 
END

How to write the above line using JOOQ?

回答1:

Your best option is to directly translate your SQL clause to a corresponding jOOQ clause using the CASE expression (as documented in the manual)

.orderBy(DSL.decode().when(BillAmount.le(0), BillAmount)
                     .otherwise(BillNumber))
