可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Could someone please guide me on how to use alias in jOOQ. I tried looking into jOOQ documentation but it is not clear. Please provide an example if possible. 回答1: Both org.jooq.Table and org.jooq.Field types implement org.jooq.AliasProvider . This means, that you can call as(String) on them, to create an aliased object. Example: Table<?> aliasedTable = MY_TABLE.as("t"); Field<?> aliasedField = MY_FIELD.as("f"); The examples from the jOOQ manual include: TBook book = T_BOOK.as("b"); TAuthor author = T_AUTHOR.as("a"); create.select(author.ID,

UPSERT in PostgreSQL using jOOQ

I am trying to perform an UPSERT in PostgreSQL using the jOOQ library. For doing this I am currently trying to implement the following SQL statement in jOOQ: https://stackoverflow.com/a/6527838 My code looks like this so far: public class UpsertExecutor { private static final Logger logger = LoggerFactory.getLogger(UpsertExecutor.class); private final JOOQContextProvider jooqProvider; @Inject public UpsertExecutor(JOOQContextProvider jooqProvider) { Preconditions.checkNotNull(jooqProvider); this.jooqProvider = jooqProvider; } @Transactional public <T extends Record> void executeUpsert(Table<T>

jOOQ Field<T> = DSL.any(DSL.val(T…))

问题 This question is a spin-off from ANY operator with jOOQ and Are arrays optimized in jOOQ & PostgreSQL?. I have a Field<T> field and List<T> values and I want to express SQL identifier = any({... the values ...}) . I tried doing: field.equal(DSL.any(DSL.val(values.stream().toArray()))) (Note this is part of a generic implementation, so I don't have the actual types at this point. I only have Field<T> and List<T> .) But this doesn't work, since the API accepts T... instead of Object... and

JOOQ and Spring

Has anyone tried using JOOQ with the Spring framework or am I breaking new ground? http://www.jooq.org Yes, many people have (by now). And the jOOQ manual includes a tutorial about how to get started using jOOQ , Spring, Spring-TX and BoneCP : http://www.jooq.org/doc/latest/manual/getting-started/tutorials/jooq-with-spring/ There is also a very good tutorial by Petri Kainulainen, explaining every step to set up a project, here: Using jOOQ with Spring: Configuration Using jOOQ with Spring: Code Generation Using jOOQ with Spring: CRUD Using jOOQ with Spring: Sorting and Pagination Here's a blog

How to generate sql from template with order by parameter using jOOQ?

一笑奈何 提交于 2019-12-02 15:49:11
问题 I generate the sql template like this with jOOQ 3.11.11. DSLContext context = new DefaultDSLContext(conf); Query query = context.select() .from("table1") .where(DSL.field("report_date").eq(DSL.param("bizdate"))) .orderBy(DSL.param("sort")); String sqlTemp = context.renderNamedParams(query); sql template: select * from table1 where report_date = :bizdate order by :sort The sql template is stored and the params are decided by realtime query condition. ResultQuery resultQuery = context

Convert Hibernate @Formula to JOOQ field

会有一股神秘感。 提交于 2019-12-02 11:26:03
问题 I am rewriting entire DB access layer from Hibernate to JOOQ and I face following issue. One of JPA models is annotated with @Formula annotation as follows: @Formula("fee1 + fee2 + fee3 + fee4") private BigDecimal fee5; Later in the code, a JPA query is made against the database which compares fee5 to parameter: SELECT ... FROM ... WHERE fee5 > input; How can above query be translated to JOOQ DSL? 回答1: I managed to resolve the issue with following JOOQ query: BigDecimal input = ...; Field

How build a JOOQ custom generator?

I have a specific Postgre schema that gathers all tables that defines types, like Status(name, description) where values could be OPEN, Open item status , CLOSED, Closed item status , etc. We need to fetch all these tables and generate enums based on them to later use it within our app. So, these enums should look like: enum Status { OPEN("Open item status"), CLOSED("Closed item status") ... } We decided to use JOOQ which looks pretty interesting, but we cannot find documentation/examples to create a custom generator that use default java generator behavior plus a custom enum generation
