jooq

问题 I'm relatively new to SBT. I'd like to include the jooq-sbt-plugin (GitHub) in my SBT config. I'm using Build.scala to handle multiple projects and I'd like to include the jooq-sbt-plugin config there but I couldn't figure out where to put it. import sbt._ import Keys._ object SampleBuild extends Build { lazy val all = Project(id = "all", base = file("."), settings = defaultSettings) aggregate( one, two ) lazy val one = Project( id = "one", base = file("one"), settings = defaultSettings ++

问题 I am trying to achieve something similar like the below MySql query in Jooq: Select CASE WHEN (datecolumn IS NULL) THEN (@outerval:=@outerval+1) ELSE (@outerval) END AS consec_set From some_table; How can we have @variable in JOOQ ? Note: I am aware the equivalent for CASE WHEN in JOOQ but just want to know the @variable. Jooq Version :3.0.1 回答1: This is currently not supported in jOOQ 3.0. I have registered a feature request for this: https://github.com/jOOQ/jOOQ/issues/2558 I'm not sure how

问题 Here is a query that I want to try out in MySQL SELECT A.x FROM A WHERE A.y = 'P' UNION SELECT A.x FROM A WHERE A.y = 'Q' The above is a cut-down, much simpler version of the original query that I am trying. In my original query, each SELECT statement involves multiple tables with INNER JOIN If the possible number of values in 'y' column of table 'A' that I need to query upon is 'n', then my query will involve doing 'n-1' unions on 'n' SELECT statements I know that JOOQ can do union of

问题 While looking for java libraries to build queries in a database agnostic way I came across many including iciql, querydsl, jooq, joist, hibernate etc. I wanted something that does not require configuration files and can work with dynamic schemas. For my application, I come to know about the database and the schema at runtime so I won't have any configuration files or domain classes for the schema. This seems to be one of the core goals of querydsl but going through the documentation for

问题 Environment: Spring application, using JOOQ 3.7, generating the JOOQ mapping code automatically from the schema, using Postgres as my database. I've been porting some code from Hibernate to JOOQ. The Hibernate code pulls some authentication details stashed away on a per context basis to populate fields like "createdBy", "updatedBy", dates, etc. The only way I can see to do this with JOOQ at the moment is that developers would have to remember to write code to update the fields by hand every

问题 I already went through link: java.lang.ClassNotFoundException: org.jooq.util.JavaGenerator and following https://www.javacodegeeks.com/2016/03/springboot-working-jooq.html. I am using Java8 and Spring Boot 2.2.2.RELEASE . I build the project using >mvn clean install -P mysql , but its giving me below error. Caused by: java.lang.ClassNotFoundException: org.jooq.util.DefaultGenerator at java.net.URLClassLoader.findClass (URLClassLoader.java:381) at java.lang.ClassLoader.loadClass (ClassLoader

问题 I want to know Best practices for initilizing JOOQ generated DAO. Now,I am using following approach for initilization of JOOQ generated DAO. In following case StudentDao is JOOQ generated. public class ExtendedStudentDAO extends StudentDao { public ExtendedStudentDAO () { super(); } public ExtendedStudentDAO (Connection connection) { Configuration configuration = DSL.using(connection, JDBCUtils.dialect(connection)).configuration(); this.setConfiguration(configuration); } //adding extra

问题 I'm experimenting with jOOQ and Kotlin and seen some tutorials and docs and it looks really nice. But if there is something very annoying with jOOQ is the code generation. It seems too complex, and eventually impossible to maintain. I decided to create my own table models (similar to how hibernate works). I created two table models: User data class User( val id: String = UUID.randomUUID().toString(), val name: String, val email: String, val password: String? = null ) { companion object { val

问题 I define a type T and a view V in a PostgreSQL database. CREATE TYPE my_type AS ( mt_column1 smallint NOT NULL ); CREATE VIEW my_view AS SELECT some_column_id integer ARRAY(SELECT ROW(an_int)::my_type FROM a_table ) AS my_view_types FROM a_regular_table WHERE my_condition_hold); Using the code generation on release 3.7 I get both an UDT record class MyTypeRecord and a table record class MyViewRecord and the UDT POJO class MyType and table POJO class MyView . The MyView generated class has an

问题 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
