There are always a few topics in regards to writing SQL that always seem to come up more often than others. Querying data with case insensitivity is one of those topics. And Oracle has addressed this issue in many of their release. But in Oracle 10gR2 they have reached new levels. This article takes a dive into case insensitivity and how it is now handled in 10gR2. For the better!
DML error logging is a new feature for 10gR2. Have you ever tried to update 30 million records, only to have the update fail after twenty minutes because one record in 30 million fails a check constraint? Or, how about an insert-as-select that fails on row 999 of 1000 because one column value is too large? With DML error logging, adding one clause to your insert statement would cause the 999 correct records to be inserted successfully, and the one bad record to be written out to a table for you to resolve.
In this article Mark explais how one can drill from a "Discoverer for OLAP worksheet" to a "Discoverer Plus Relational worksheet" using Discoverer 10.1.2.
On our quest to learn about Oracle's Data Pump utility it has often been compared to the old export and import (exp & imp) utilities that we have all grown to love (or hate). This article is where where Data Pump takes a detour from these old utilities and begins to shine. This article will explore some of the export modes available and give examples on how to export selected object types and dependencies those objects have.

"I have a question about drilling from an OracleBI Discoverer for OLAP 10.1.2 worksheet to a Discoverer Plus Relational worksheet. When you pass values from an OLAP worksheet you pass either the dimension name or the dimension value to the associated parameter in the relational worksheet. Obviously, in OLAP this dimension is treated as an object, and we have no idea which level the user may have picked before he drills out. On the other hand, in the relational world, each level of the dimension would be split out as a separate parameter. Could you run through a simple example where you drill from an OLAP worksheet to a relational worksheet and show how this is done?"
Oracle recommends that RAC databases be managed with srvctl, an Oracle-supplied tool that was first introduced with 9i RAC. The 10g version of srvctl is slightly different from the 9i implementation. In this article, we will look at how -- and why -- to manage your 10g databases with srvctl.
In this article, Mark explains how the SQL MODEL clause can be used to generate rather complex financial statements.
Since we are all familiar with Oracle’s original export (exp) utility, and in my opinion Data Pump will be replacing exp soon, I thought it would be good to start off getting familiar with this utility by some relatively simple Data Pump exports (expdp) that are similar to the way we have used exp in the past. In particular the FULL export.
One of the most powerful features of the multidimensional engine behind analytic workspaces is the ability to create formulas. Formulas, or "calculated measures" as they're referred to in AWM10g, are measures that are derived from other measures. Using AWM, you can create simple formulas that reference other measures in a cube, allowing you for example to create a "margin" measure derived from sales and costs measures. If you're an old Express hand though, you'll know that this simple type of formulas is just the tip of the iceberg, and what you often used to end up doing was creating for example a three dimensional formula based on measures from four and five dimensional variables, rolling up unneeded dimensions and pulling in variables held in what would now be referred to as "cubes".
