		<description><![CDATA[Will competitors such as Hewlett-Packard, IBM, and SAP follow Oracles lead when it comes to big data?  Some analysts believe so, as they claim Oracles recent release of its Big Data Appliance running Clouderas distribution of Apache Hadoop will likely catch the eye of IT managers looking for a comprehensive solution for their corporate data needs.]]></description>
		<content:encoded><![CDATA[Oracle first introduced its Big Data Appliance as well as the NoSQL database at the company's OpenWorld user conference last October. According to analyst David Menninger of Ventana Research, the appliance was created to manage and analyze data sets deemed to be too large for storing in standard databases. The Big Data Appliance boasts a lineup including Sun server hardware (18 Linux-based x86 Sun servers with 216 processor cores, 648TB raw disk storage, 864GB working memory), Oracle NoSQL database, Oracle's Java HotSpot Virtual Machine, and an open-source distribution of R.

		<content:encoded><![CDATA[Headlining PeopleTools 8.52's list of improvements is support for Apple's popular iPad tablet.  The move makes Oracle the lone enterprise resource planning vendor to provide an enterprise suite on the iPad, giving users the ability to access PeopleSoft on the go while maintaining the functionality and security one would normally expect in a stationary setting. While iPad support is appealing, it's just the tip of the iceberg when it comes to PeopleTools 8.52's enhancements.  The user interface has been upgraded to improve interactivity through the use of new pagelets and inter-pagelet communic...]]></content:encoded>

		<content:encoded><![CDATA[The highlight of the latest update includes a number of statements marked as unsafe for statement-based replication.  According to the H Open website, all of the statements given the distinction of being unsafe supposedly  rely on the result of a select statement where the order cannot be relied upon.   Oracle recommends that any users who engage in statement-based logging should read the accompanying documentation for additional guidance regarding the issues addressed in the update.  Beyond the replication issue, Oracle also used MySQL 5.5.18 to fix a problem  where the master could send dama...]]></content:encoded>

		<content:encoded><![CDATA[In addition to the NoSQL Database release, Oracle also announced that its highly anticipated Big Data Appliance would become available during the first quarter of 2012.  Oracle initially gave a sneak peek into both products at the Oracle Open World Conference in San Francisco a few weeks ago, so the rather quick availability and updated information show that the company is taking aggressive steps to measure up to the competition. The timing of Oracle's announcements could not be any better, as its competitors are also making moves in the large-scale data processing arena.  EMC and IBM kicked t...]]></content:encoded>

		<description><![CDATA[In this conclusion to a multi-part series on using the SELECT statement in an Oracle database, you'll learn how to sort a result set by an alias, an expression, or a column number. This article is excerpted from chapter three of the book Murach's Oracle SQL and PL/SQL, written by Joel Murach (Murach Publishing; ISBN: 9781890774509).]]></description>
		<content:encoded><![CDATA[How to sort a result set by an alias, an expression, or a column number  Figure 3-18 presents three more techniques that you can use to specify sort columns. First, you can use a column alias that's defined in the SELECT clause. The first SELECT statement in this figure, for example, sorts by a column named address, which is an alias for the concatenation of the vendor_city, vendor_state, and vendor_zip_code columns. Within the address column, the result set is sorted by the vendor_name column.  You can also use an arithmetic or string expression in the ORDER BY clause, as illustrated by the s...]]></content:encoded>

		<description><![CDATA[In this eighth part of a nine-part article series focusing on the SELECT statement and its usage in retrieving data from tables, you'll learn how to use the LIKE operator and much more. This article is excerpted from chapter three of the book Murach's Oracle SQL and PL/SQL, written by Joel Murach (Murach Publishing; ISBN: 9781890774509).]]></description>
		<content:encoded><![CDATA[How to use the LIKE operator  One final operator you can use in a search condition is the LIKE operator, shown in figure 3-15. You use this operator along with the wildcards shown at the top of this figure to specify the string pattern, or mask, that you want to match. The examples in this figure show how this works.  In the first example, the LIKE phrase specifies that all vendors in cities that start with the letters SAN should be included in the query results. Here, the percent sign (%) indicates that any characters can follow these three letters. So San Diego and Santa Ana are both include...]]></content:encoded>

		<description><![CDATA[In this seventh part of a nine-part series, you will learn how to use the IN and BETWEEN operators, along with the SELECT statement, to retrieve data from a single table. This article is excerpted from chapter three of the book Murach's Oracle SQL and PL/SQL, written by Joel Murach (Murach Publishing; ISBN: 9781890774509).]]></description>
		<content:encoded><![CDATA[How to use the IN operator  Figure 3-13 shows how to code a WHERE clause that uses the IN operator. When you use this operator, the value of the test expression is compared with the list of expressions in the IN phrase. If the test expression is equal to one of the expressions in the list, the row is included in the query results. This is illustrated by the first example in this figure, which will return all rows whose terms_id column is equal to 1, 3, or 4.  You can also use the NOT operator with the IN phrase to test for a value that's not in a list of expressions. This is illustrated by the...]]></content:encoded>

In the topics that follow, you'll learn a variety of ways to code this clause.  How to use the comparison operators  Figure 3-11 shows you how to use the comparison operators in the search condition of a WHERE clause. As you can see in the syntax summary at the top of this figure, you use a comparison operator to compare two expressions. If the result of the comparison is True, the row being tested is included in the query results.  The examples ...]]></content:encoded>

This article is excerpted from chapter three of the book Murach's Oracle SQL and PL/SQL, written by Joel Murach (Murach Publishing; ISBN: 9781890774509).]]></description>
		<content:encoded><![CDATA[How to use the DISTINCT keyword to eliminate duplicate rows  By default, all of the rows in the base table that satisfy the search condition in the WHERE clause are included in the result set. In some cases, though, that means that the result set will contain duplicate rows, or rows whose column values are identical. If that's not what you want, you can include the DISTINCT keyword in the SELECT clause to eliminate the duplicate rows.  Figure 3-9 illustrates how this works. Here, both SELECT statements retrieve the vendor_city and vendor_state columns from the Vendors table. The first statemen...]]></content:encoded>

		<content:encoded><![CDATA[How to use scalar functions  Figure 3-7 introduces you to scalar functions, which operate on a single value and return a single value. These functions work differently than the aggregate functions described in chapter 5 that are used to summarize data. For now, don't worry about the details of how these functions work, because you'll learn more about them in chapter 8. Instead, just focus on how they're used in column specifications.  To code a function, you begin by entering its name followed by a set of parentheses. If the function requires one or more parameters, you enter them within the p...]]></content:encoded>

		<content:encoded><![CDATA[How to code string expressions  A string expression consists of a combination of one or more character columns and literal values. To combine, or concatenate, the columns and values, you use the concatenation operator (||). This is illustrated by the examples in figure 3-5.  The first example shows how to concatenate the vendor_city and vendor_state columns in the Vendors table. Notice that because no alias is assigned to this column, Oracle assigns a name, which is the entire expression. Also notice that the data in the vendor_state column appears immediately after the data in the vendor_city...]]></content:encoded>
