生成以下SQL
SELECT "PUBLIC"."image"."name",
"PUBLIC"."product"."name"
FROM "PUBLIC"."image"
JOIN "PUBLIC"."product"
ON "PUBLIC"."image"."product_id" = "PUBLIC"."product"."id"
WHERE ( Lower("PUBLIC"."product"."name") LIKE Lower('%tv%')
AND "PUBLIC"."image"."index" > 0 )
ORDER BY "PUBLIC"."image"."name" ASC
这是我第一次使用JOOQ，花了我太多时间浏览文档并在Hibernate Facts编码示例中进行了所有设置。JOOQ查询的构建感觉很自然，就像编写本机SQL代码一样，因此我不必真正学习API就能知道如何使用它。我将很自豪地将其添加到我的Java Data Toolbox中。
