JSON_TABLE or XMLTABLE - comparison with geocoding

Previously I've demonstrated how to use function XMLTABLE to query Google maps routing directions. Now Oracle version 12.1.0.2.0 has function JSON_TABLE to do similar querying on JSON data rather than XML data. So let's try that out and spot some differences...

Oracle 12c Row Pattern Matching: Beat the Best Pre-12c Solutions at OpenWorld!

Catchy title, don’t you think? My session has been moved to Monday 4 P.M., in direct conflict with Tom Kyte – and Keith Laker, who asked me to present in the first place. Avoid the lines: come see the MATCH_RECOGNIZE clause push great pre-12c solutions into retirement. As a bonus, be the first person on your block able […]

E-Business Customers

It seems the Oracle E-Business Suite stymies newbies. It’s complex and requires some research before you try to develop customization.

PRECOMPUTE_SUBQUERY hint

I’ve just found out that we can specify query block for PRECOMPUTE_SUBQUERY: /*+ precompute_subquery(@sel$2) */

AIOUG Tech Day at Hyderabad (Aug 23rd)

Hi there, Last week, I spoke at AIOUG Tech Day at Hyderabad. All India Oracle Users Group (AIOUG) in association with TechMahindra organized one full day of techtalk event. Believe me, the Danube auditorium was a state-of-art facility with 500 capacity. Fabulous venue and huge crowd with similar interest.

Flipping Herman Millers

I was one of those dot.com boom excitables who decided that he must own a Herman Miller Aeron chair in order to be super cool and incredibly productive while I blogged and tweeted (well, I don't think there was Twitter back then) and so forth.

Soon after I got the chair, I realized that I really didn't like it very much at all. It didn't seem to provide support in the right places, didn't make it easy to avoid slouching....it wasn't the desk chair for me.

You can read my tale of woe, or skip to the .bashrc function that fixed it when I installed only rlwrap.
