Use JOOQ to do a delete specifying multiple columns in a "not in" clause

Question

I want to bring a postgres database table in sync with a list of Jooq Records.

I have a table with a composite primary key and three other values in each row

table(k1, k2, v1, v2, v3)

For example, the data might be

Last, First, Age, Weight, Height
Smith, Joe,  21,  75,     160
Jones, Pete, 23,  80,     180

(excuse the poor form of using names as primary keys....)

I also have a list of Jooq Records for that table in my java code. Let's say that there's two java records

[
   <Smith, Joe, 21, 75, 180>,
   <Taylor, Mark, 54, 90, 170> 
]

What I would want to happen is when I run some code,

• The database row for Joe Smith has it's height updated
• A new row is inserted for Mark Taylor
• The database row for Pete Jones is deleted

I have managed to create a function that does the first two parts, but am stuck on the third. I was hoping to have a pretty simple "one liner" in JOOQ that basically did

delete 
from my_table 
where (first, last) not in (values ('Joe', 'Smith'), ('Mark', 'Taylor')) 

but I can't work out the corresponding Java code to do it.

Are there any Jooq-masters reading this?

Is there an obvious thing I'm over-looking?

Answer 1

Your query can be translated to the following jOOQ code:

// Assuming this:
import static org.jooq.impl.DSL.*;

using(configuration)
   .deleteFrom(MY_TABLE)
   .where(row(MY_TABLE.FIRST, MY_TABLE.LAST).notIn(
        row("Joe", "Smith"),
        row("Mark", "Taylor")
   ))
   .execute();

This is using DSL.row() to construct row value expressions. Note that ROW is an optional keyword in PostgreSQL. You just happened to omit it in your SQL example.
