- Scalar subqueries simplify complex SQL statements
- Scalar subqueries are yet another great enhancement to Oracle9i. They can combine multiple queries into a single query, greatly simplifying complex SQL statements.Scalar subqueries are a powerful enhancement to Oracle9i SQL. They allow for quick formulation of extremely complex SQL statements. Oracle’s introduction of scalar subquery support is another example...

- XML Schema: Understanding Datatypes
- The W3C XML Schema Datatype Specification defines numerous datatypes for validating the element content and the attribute value. These datatypes can be used to validate only the scalar content of elements, and not the non-scalar or mixed content. The text enclosed between the and element tags, and the value of...

- Mini-Tip #8 - Extending XMLType to Access Scalar XPath Functions
- For some reason, the XMLType XPath implementation does not allow scalar results. According to the documentation:EXTRACTXML is similar to the EXISTSNODE function. It applies a VARCHAR2XPath string and returns an XMLType instance containing an XML fragment.Extractwill only return an XMLType. A scalar value would be a function thatreturns a...

- Tape Consolidation With the Sun Storagetek L1400 Tape Library - Achieving Midrange Storage Efficiencies: An Overview and Comparison With the Quantum Scalar i2000
- This paper introduces general tape consolidation concepts and describes the Sun StorageTek L1400 tape library features that support consolidation. Consolidation benefits fall into three key areas: improved IT productivity, the ability to respond quickly to changing business priorities, and lowered TCO through increased asset utilization. In support of these areas,...

- IBM supercomputing goes retro
- Never is a Long Time...Perhaps "soon to Famous" Last Words, from Cray engineer: Steve Scott, an X1 chief architect. "Trying to hook multiple scalar processors into a vector processor is never going to be as effective as a real vector processor."This remark may sound like Bill Gates' remark in the...

- Understand when to use user-defined functions in SQL Server
- Thank Tim.Good information.You said, "I usually discourage using scalar-valued UDFs in a WHERE criteria statement" and that's exactly some of the things a developing database manager, like myself, needs to know. It's one of those things I find myself wondering about, but I just can't make the time to...

- Incorporate SQL Server UDFs in your .NET applications
- Database interaction is a standard feature of most .NETapplications, with SQL Server as the popular choice for the data tier.Consequently, .NET developers often find themselves developing T-SQL codewithin their applications or stored procedures on the database server.Developers often overlook a number of the features in theT-SQL language. For instance, when...

- On the Behavior of Optimal Scheduling Algorithms Under TCP Sources
- This paper focuses on the dynamical interaction between regulated Additive Increase Multiplicative Decrease AIMD traffic sources and the max-scalar scheduling policy, which has been proved to be optimal in terms of throughput in case of stationary unregulated traffic sources. It describes the average dynamics of both sources and queues dynamics...

- Understand when to use user-defined functions in SQL Server
- In the simplest terms, a user-defined function UDF in SQL Server is a programming construct that accepts parameters, does work that typically makes use of the accepted parameters, and returns a type of result. This article will cover two types of UDFs: table-valued and scalar-valued. (I will not be covering...

- Semi-Oblivious Routing: Lower Bounds
- This paper initiates the study of semi-oblivious routing; a relaxation of oblivious routing which is first introduced by Racke and led to many subsequent improvements and applications. In semi-oblivious routing like oblivious routing, the algorithm should select only a polynomial number of paths between the source and the sink of...

- On the Interaction Between TCP-Like Sources and Throughput-Efficient Scheduling Policies
- This paper focuses on the dynamic interaction in packet networks between regulated Additive-Increase Multiplicative-Decrease AIMD traffic sources and max-scalar scheduling policies (such as the popular Maximum Weight Matching - MWM) at switches. The latter were proved to be optimal in terms of throughput for stationary unregulated traffic sources. It describes...
