Add count as select field using jooq SelectQuery

问题

Most of the existing posts I can find dealing with my learning jook are outdated.

I'm trying to build dynamically so that I can use conditions for certain changes. I'm trying to find how to add COUNT(*) to an existing list of fields

SelectQuery query = create().selectQuery();
query.addSelect(TABLE.FIELD);
// add COUNT(*)?

I'm not seeing any methods or API help on how to do this when building the query dynamically.

回答1:

Just use DSL.count()

query.addSelect(count());

The above is assuming a static import as such:

import static org.jooq.impl.DSL.*;
