Oracle Database INTERVAL Partitioning and Virtual Columns

I bumped into this issue recently which prevents you INSERTING a date of 31-12-9999 into an INTERVAL partitioned table due to the fact that the LESS THAN partition value would be larger than an Oracle Date. After speaking with Jeff Moss he mentioned that we might be able to get round the problem by using a virtual

Truncates and Sequences Replication in Oracle GoldenGate

We use the terms DDL and DML in our DBA life with Oracle all the time. The first stands for Data Definition Language and it is about Data Definition changes. The latter is about manipulation with your data itself, and stands for Data Manipulation Language. When we speak about replication of our data by replication tools between Oracle databases, we generally either enable DDL, work only replicating DML, or do it for both together. In (more...)

Oracle Database INTERVAL Partitioning Date Error With 31-12-9999

You may have seen the below error when using dates at the extremes with an Oracle Database. This post focuses on the scenario where you’re inserting a high date, such as 31-12-9999 into an INTERVAL partitioned table.

CQRS with Java and Lagom

I've had the pleasure to talk at the Chicago Java User Group and talk about how Lagom implements CQRS, the Command Query Responsibility Segregation pattern. Thankfully, there is a recording and I also published the slides on slideshare.

Abstract:
As soon as an application becomes even moderately complex, CQRS and an Event Sourced architecture start making a lot of sense. The talk is focused on: - the challenges and tactics of separating the write model (more...)

Little enhancements are always nice

Before LATERAL and CROSS APPLY were added (exposed to us) in 12c, a common technique to do correlated joins was using the TABLE/MULTISET technique.

For example, we might have had a couple of tables:


SQL> create table t as
  2  select object_type, min(created) min_dte, max(created) max_dte
  3  from dba_objects
  4  where owner = 'SCOTT'
  5  group by object_type;

Table created.

SQL> select * from t;

OBJECT_TYPE         MIN_DTE   MAX_DTE
------------------- --------- ---------
INDEX               09-OCT-13 09-OCT-13

The Nextbit Robin

For a couple of months, I’ve been using as my main phone the Nextbit Robin. A $299 Android phone that started as a campaign in Kickstarter, and it got 3,611 backers including Jake (@jkuramot).

I previously had my Nexus 5, but over the time, Bluetooth stopped working and that was a good excuse to try this phone.

Also I was so excited because at SXSW I had a long talk with the Nextbit (@ (more...)

Size Does Matter
