kandi X-RAY | jOOQ Summary

jOOQ is a Java library typically used in Database, SQL Database, Hibernate, JPA, Oracle applications. jOOQ has no bugs, it has no vulnerabilities, it has build file available and it has medium support. However jOOQ has a Non-SPDX License. You can download it from GitHub, Maven.

Other platforms incorporate ideas such as LINQ (with LINQ-to-SQL), or Scala’s SLICK, or also Java’s QueryDSL to better integrate querying as a concept into their respective language. By querying, they understand querying of arbitrary targets, such as SQL, XML, Collections and other heterogeneous data stores. jOOQ claims that this is going the wrong way too. In more advanced querying use-cases (more than simple CRUD and the occasional JOIN), people will want to profit from the expressivity of SQL. Due to the relational nature of SQL, this is quite different from what object-oriented and partially functional languages such as C#, Scala, or Java can offer. It is very hard to formally express and validate joins and the ad-hoc table expression types they create. It gets even harder when you want support for more advanced table expressions, such as pivot tables, unnested cursors, or just arbitrary projections from derived tables. With a very strong object-oriented typing model, these features will probably stay out of scope. In essence, the decision of creating an API that looks like SQL or one that looks like C#, Scala, Java is a definite decision in favour of one or the other platform. While it will be easier to evolve SLICK in similar ways as LINQ (or QueryDSL in the Java world), SQL feature scope that clearly communicates its underlying intent will be very hard to add, later on (e.g. how would you model Oracle’s partitioned outer join syntax? How would you model ANSI/ISO SQL:1999 grouping sets? How can you support scalar subquery caching? etc…​). jOOQ has come to fill this gap.

            Which Code generator should be used for SQL Server
            Asked 2022-Apr-07 at 14:38

            I use my liqibase scripts for Jooq code generation. As I learned from the instructions and log, the Dialect is H2.

            Is that a problem if the application runs against a SQL Server database afterwards? Does the code generation have to be adjusted or do the metaclasses remain the same?

            ...

            ANSWER

            Answered 2022-Apr-07 at 14:38

            The LiquibaseDatabase can be used for simple database schemas where it is desirable not to connect to an actual database instance (e.g. for performance reasons) in order to generate code. It's drawbacks are that it's not an actual SQL Server database, but a simulated migration - currently on an in-memory H2 database. This means that some vendor specific functionality may not work as expected.

            It is usually better not to use the above utility for more complex schemas with vendor specific features (e.g. stored procedures, etc.). Instead, use the SQLServerDatabase that connects to an actual database instance.

            You could still use Liquibase on a testcontainers based SQL Server instance to set up your schema prior to generating jOOQ code, as explained in this blog post here.

            Answered 2022-Mar-22 at 09:09

            The error isn't related to your specific query, but to your dependency management.

            The java.util.concurrent.Flow class has been added to the JDK 9 only, it was not yet available in the JDK 8. Starting from jOOQ 3.15, the jOOQ Open Source Edition had a Java 11 baseline and thus a direct dependency on JDK 11 API, including Flow. If you wish to continue working with Java 8 and jOOQ 3.15, you will need to upgrade to the commercial distributions, which have continued support for Java 8. You can find jOOQ's Java version support matrix here: https://www.jooq.org/download/versions

            A common reason why you might still be accidentally pulling the jOOQ Open Source Edition dependency and thus run into this error, despite using the commercial editions, could be related to using a third party dependency management framework, such as Spring Boot, which defaults to depending on the jOOQ Open Source Edition. This blog post explains how to work around that: https://blog.jooq.org/how-to-use-jooqs-commercial-distributions-with-spring-boot/

            Also, make sure you're using the right dependencies both in your code generation setup as well as at runtime, as you can see in this section of the manual.

            This is most likely due to a bug: https://github.com/jOOQ/jOOQ/issues/12997

            Explanation and workaround

            Behind the scenes, in jOOQ 3.16, the LiquibaseDatabase, DDLDatabase, and JPADatabase all simulate your database migrations using an in-memory H2 database. This might be changed in the future, but that's how it works now. In H2, by default, all identifiers are in upper case, and so is the configuration. This means you should be including the PUBLIC schema, not the public schema.

            Note that also code generation output will contain references to PUBLIC, not public, so if you want to continue using the LiquibaseDatabase, you'll have to turn off quoting of identifiers at runtime using the RenderQuotedNames setting.

            More robust alternative that doesn't simulate Liquibase on H2

            Alternatively, you don't have to use the LiquibaseDatabase, as I've mentioned elsewhere. You can also use testcontainers to run an actual migration directly on PostgreSQL, and reverse engineer an actual PostgreSQL database, instead, as described in this blog post.

            If you want to nest collections in with jOOQ, then you're probably looking for the MULTISET or MULTISET_AGG operator along with ad-hoc conversion, which allows for type safe nesting collections directly in SQL, if your database product support SQL/XML or SQL/JSON.

            Client side ResultSet reading

            The ResultQuery.fetchAny() method only defines client side behaviour between jOOQ and JDBC. It proceeds to fetch at most one record from the underlying JDBC ResultSet. In short:

            • ResultQuery.fetchAny() fetches the first record (if available) from the ResultSet
            • ResultQuery.fetchOne() fetches the first record (if available) from the ResultSet and attempts to fetch another one, in case of which it throws TooManyRowsException
            • ResultQuery.fetchSingle() fetches the first record from the ResultSet, throws NoDataFoundException if no such record was found, and attempts to fetch another one, in case of which it throws TooManyRowsException

            These methods do not communicate to the server anything about the intended result set usage, so the server doesn't know what you're planning to do.

            Server side locking

            This is unrelated to how you use SQL pessimistic locking clauses, such as FOR UPDATE SKIP LOCKED, which is an operation that happens purely on the server side, and ideally on the entire data set satisfying your WHERE, LIMIT, and other clauses. Even if this weren't the case, it's always better to be very explicit about everything you know about your SQL query directly in SQL.

            So, since you're going to fetch only one record, why not tell the server, using LIMIT 1?

            Why the duplicates?

            Your join graph creates a cartesian product between the two "nested collections" ROLE and PERMISSION. You can't remove that cartesian product with GROUP BY alone, that works only if you join a single to-many relationship.

            Instead, you can write subqueries like this (you already did this correctly for the ROLE_PERMISSION relationship):

            Select ordering works differently on windows and in container
            Asked 2021-Dec-20 at 16:17

            I'm facing problem with ordering database records. I'm using jOOQ and DSLContext in SpringBoot application to select data from configured Oracle database. Everything works fine locally on my Windows device. After deploying application to Openshift container platform, the same select orders records differently. Database contains text values in Slovak language with accents and special characters as you can see in result tables.

            Select:

            The jOOQ API supports collations, which is the SQL way of specifying the sort order for different character sets and locales. You could write:
