postgres 'WITH' clause with jooq
问题 Hell, I can't find a way to use the postgres 'WITH' clause with JOOQ. Could you please let me know if it's supported by JOOQ? Thanks 回答1: Common table expressions (the " WITH clause") are currently not supported in jOOQ. There is a pending feature request on the jOOQ road map for CTE's: #454. As of jOOQ 3.0, there are currently no plans of actually supporting it, though.

JOOQ query to JOIN ON WITH clause
问题 How can I write a JOOQ query to join on a field from a "with" clause? For example, I've tried: create.with("a").as(select( val(1).as("x"), val("a").as("y") )) .select() .from(tableByName("a") .join(ANOTHER_TABLE) .on(ANOTHER_TABLE.ID.eq(tableByName("a").field("x"))) .fetch(); However, as the compiler doesn't know the type of tableByName("a").field("x") it cannot resolve which eq() method to use. Given that I know the type, is there a way I can provide it explicitly? Or is there another

What with clause do? Neo4j
I don't understand what WITH clause do in Neo4j. I read the The Neo4j Manual v2.2.2 but it is not quite clear about WITH clause. There are not many examples. For example I have the following graph where the blue nodes are football teams and the yellow ones are their stadiums. I want to find stadiums where two or more teams play. I found that query and it works. match (n:Team) -[r1:PLAYS]->(a:Stadium) with a, count(*) as foaf where foaf > 1 return a count(*) says us the numbers of matching rows. But I don't understand what WITH clause do. WITH allows you to pass on data from one part of the
T-SQL: multiple usage of CTE alias - not only in outer query
I've got a question which occurs when I was using the WITH-clause in one of my script. The question is easy to pointed out I wanna use the CTE alias multiple times instead of only in outer query and there is crux. For instance: -- Define the CTE expression WITH cte_test (domain1, domain2, [...]) AS -- CTE query ( SELECT domain1, domain2, [...] FROM table ) -- Outer query SELECT * FROM cte_test -- Now I wanna use the CTE expression another time INSERT INTO sometable ([...]) SELECT [...] FROM cte_test The last row will lead to the following error because it's outside the outer query: Msg 208,
