Formatting Code With SQL Developer

Introduction I started using SQL Developer in 2013. Back then version 4.0 was the latest and greatest. But the capabilities of the formatter were disappointing. In 2017 Oracle released version 4.2 with a new formatter and has been improving it ever since. Version 19.2 brought us dynamic JavaScript actions within the parse-tree […]

View-API for JOOQ Application

In this blog post, I show how to build a read-only view-API for Oracle’s HR sample schema. And I will use this view-API in a JOOQ application.

Is Your Application SmartDB?

I recently had a few discussions regarding the Smart Database Paradigm (SmartDB) with long-standing customers, new customers, partners, competitors and colleagues. Some people think that using APEX and PL/SQL in their database application is SmartDB. But it is not that simple.

MemOptimized RowStore in Oracle Database 18c with OCI
