jooq

Yes! I have read the docs about jOOQ will never commit or rollback on the Connection (Except for CSV-imports, if explicitly configured in the Import API) jOOQ will never start any transactions. ... but when I need some transaction management, what is the best practice to do this? Have I said that I'm a big fan of a way of JOOQ! This question was asked at a time when jOOQ did not yet implement a transaction API. As of jOOQ 3.4 onwards, such an API is available and documented here: https://www.jooq.org/doc/latest/manual/sql-execution/transaction-management Transaction API and its default binding

I had a question.. Why do I have repeat what I have selected in the fetch method. Date minDate = getDSLContext() .select(CON_CAL_INSTANCE.DATE.min()) .from(CON_CAL_INSTANCE) .join(CON_CAL_TEMPLATES) .on(CON_CAL_INSTANCE.TEMPLATE_ID.eq(CON_CAL_TEMPLATES.ID)) .where(CON_CAL_TEMPLATES.ENTRY_TYPE.in("REPT", "HRPT")) .fetchOne(CON_CAL_INSTANCE.DATE.min()); So I have provided CON_CAL_INSTANCE.DATE.min() in my select clause, why do I have to repeat it in fetchOne(CON_CAL_INSTANCE.DATE.min()) ? Or am I not doing this right? You're doing it right. The way the jOOQ DSL is constructed with Java generics,

With jOOQ , I may want to combine using the jOOQ code generator with Maven and a custom generator strategy . It looks as though this can be done as such (leaving out irrelevant parts): <plugin> <groupId>org.jooq</groupId> <artifactId>jooq-codegen-maven</artifactId> <version>2.2.2</version> <!-- The plugin should hook into the generate goal --> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <generator> <name>org.jooq.util.DefaultGenerator</name> <!-- But the custom strategy is not yet compiled --> <strategy> <name>com.example

My apps on Heroku use a DATABASE_URL. This is simple to parse with Java into a JDBC URL with a user name and password. There's no issue there. However, I have a JOOQ generator and Flyway migrator that have maven plugins and I can't figure out how to get the JDBC URL, User Name, and Password that these plugins require into maven. So currently I do it on app startup which is not ideal. When my app starts I get the DATABASE_URL, parse it, then do the flyway migration and jOOQ code generation. But I would like this to happen during the actual build process, not during application startup.

Ideally using Jackson on the Java side of things. I have tried the obvious solution: public class JsonObjectConverter implements Converter<Object, ObjectNode> { private final ObjectMapper mapper = new ObjectMapper(); @Override public ObjectNode from(Object dbo) { try { return dbo != null ? mapper.readValue((String) dbo, ObjectNode.class) : null; } catch (IOException e) { throw new RuntimeException(e); } } @Override public Object to(ObjectNode uo) { try { return uo != null ? mapper.writeValueAsString(uo) : null; } catch (JsonProcessingException e) { throw new RuntimeException(e); } } @Override

I use jOOQ and MySQL DB in my application. For integration tests I use H2 database and there is a problem. Is there some way to run jooq-codegen-maven plugin twice? I found some maven example for this case. However, in two different cases, I must use two different dependencies. Can I somehow to include dependency in execution? You can have multiple <execution> elements in any Maven plugin configuration, e.g. <plugin> <groupId>org.jooq</groupId> <artifactId>jooq-codegen-maven</artifactId> <version>3.9.1</version> <executions> <execution> <id>first-generation</id> <phase>generate-sources</phase>
