Specify either dbtype or dataSource. ColdFusion supports HQL in cfquery. In previous versions of ColdFusion, you could set this attribute at the datasource lavel.

In the release of ColdFusion, you can set it at the query level. For more information, see Usage. The cumulative time may exceed this value.

For other drivers, see the driver documentation. The result variable of INSERT queries contains a key-value pair that is the automatically generated ID of the inserted row; this is available only for databases that support this feature.

If more than one record was inserted, the value can be a list of IDs. The key name is database-specific. Oracle only.

The ID of an inserted row. This is not the primary key of the row, although you can retrieve rows based on this ID.

You can cache query results and execute stored procedures. The Caching page of the ColdFusion Administrator specifies the maximum number of cached queries.

Setting this value to 0 disables query caching. You cannot use ColdFusion reserved words as query names. You cannot use SQL reserved words as variable or column names in a Query of Queries, unless they are escaped.

The escape character is the bracket []; for example:. Many database configurations require authentication in the form of a username and password before you can query the database.

Note that You can also configure the user name and password in the datasource in the ColdFusion Administrator.

Specifying the authentication details in your query overrides the username and password in the ColdFusion Administrator. A timeout is useful in preventing requests that are running for more than the limit set.

The timeout attribute sets the maximum number of seconds that each action of a query is allowed to execute before returning an error.

The volume of traffic to your web site or applications impacts the performance of your site or application. To enhance the performance, you can cache your database queries.

The results are stored when the query is first run. Whenever you run the query thereafter, ColdFusion retrieves the results from memory.

In the example below, if the query's cached data is older than 60 seconds, the query is re-run. Otherwise, the cached data is used.

ColdFusion 8: Added the result variable that specifies the ID of a row. As of July , Adobe had released 10 updates [11] for ColdFusion New or improved features available in all editions Standard, Enterprise, and Developer include: [12].

In Sep , Adobe announced the roadmap anticipating releases in and As for the release, the features anticipated at that time in were configurability modularity of CF application services, revamped scripting and object-oriented support, and further enhancements to the API Manager.

The generated document can then either be saved to disk or sent to the client's browser. ColdFusion was originally not an object-oriented programming language like PHP versions 3 and below.

ColdFusion falls into the category of OO languages that do not support multiple inheritance along with Java, Smalltalk, etc.

Each component may contain any number of properties and methods. One component may also extend another Inheritance.

Components only support single inheritance. Object handling feature set and performance enhancing has occurred with subsequent releases.

With the release of ColdFusion 8, Java-style interfaces are supported. ColdFusion components use the file extension cfc to differentiate them from ColdFusion templates.

Component methods may be made available as web services with no additional coding and configuration. All that is required is for a method's access to be declared 'remote'.

Consider the GET request as shown. This will invoke the component's search function, passing "your query" and "strict" as arguments.

This type of invocation is well-suited for Ajax -enabled applications. The ColdFusion server will automatically generate documentation for a component if you navigate to its URL and insert the appropriate code within the component's declarations.

This is an application of component introspection, available to developers of ColdFusion components. Access to a component's documentation requires a password.

ColdFusion provides several ways to implement custom markup language tags, i. These are especially useful for providing a familiar interface for web designers and content authors familiar with HTML but not imperative programming.

The traditional and most common way is using CFML. For example, the file IMAP. ColdFusion can also be deployed to servlet containers such as Apache Tomcat and Mortbay Jetty , but because these platforms do not officially support ColdFusion, they leave many of its features inaccessible.

Prior to ColdFusion 7. NET by declaring them as web services. However, beginning in ColdFusion MX 7. Recently, there has been much interest in Java development using alternate languages such as Jython , Groovy and JRuby.

ColdFusion was one of the first scripting platforms to allow this style of Java development. ColdFusion 8 natively supports. ColdFusion developers can simply call any.

NET assembly without needing to recompile or alter the assemblies in any way. Data types are automatically translated between ColdFusion and.

NET example:. NET Assemblies remotely through proxy without the use of. NET Remoting. This allows ColdFusion users to leverage. NET without having to be installed on a Windows operating system.

When ColdFusion templates are saved to disk, they are traditionally given the extension. ColdFusion originated as proprietary technology based on Web technology industry standards.

However, it is becoming a less closed technology through the availability of competing products. Such alternative products include in alphabetical order :.

NET, simply because ColdFusion will run on top of a. NET application server. In March , a known issue affecting ColdFusion 8, 9 and 10 left the National Vulnerability Database open to attack.

In April , a ColdFusion vulnerability was blamed by Linode for an intrusion into the Linode Manager control panel website.

In May , Adobe identified another critical vulnerability, reportedly already being exploited in the wild, which targets all recent versions of ColdFusion on any servers where the web-based administrator and API have not been locked down.

The vulnerability allows unauthorized users to upload malicious scripts and potentially gain full control over the server.

In April , Adobe fixed a cross-site scripting XSS vulnerability [23] in Adobe ColdFusion 10 before Update 16, and in ColdFusion 11 before Update 5, that allowed remote attackers to inject arbitrary web script or HTML; [24] however, it's exploitable only by users who have authenticated through the administration panel.

In September , Adobe fixed two command injection vulnerabilities CVE that enabled arbitrary code and an alleyway traversal CVE From Wikipedia, the free encyclopedia.

Current was applied continuously for many weeks, with the heavy water being renewed at intervals. These high temperature phases would last for two days or more and would repeat several times in any given experiment once they had occurred.

The calculated power leaving the cell was significantly higher than the input power during these high temperature phases. Eventually the high temperature phases would no longer occur within a particular cell.

In Fleischmann and Pons applied to the United States Department of Energy for funding towards a larger series of experiments.

Fleischmann and Pons and co-workers met with Jones and co-workers on occasion in Utah to share research and techniques. During this time, Fleischmann and Pons described their experiments as generating considerable "excess energy", in the sense that it could not be explained by chemical reactions alone.

Jones, however, was measuring neutron flux, which was not of commercial interest. In mid-March , both research teams were ready to publish their findings, and Fleischmann and Jones had agreed to meet at an airport on 24 March to send their papers to Nature via FedEx.

Fleischmann and Pons' announcement drew wide media attention. Its discovery 30 years earlier had also been unexpected, though it was quickly replicated and explained within the existing physics framework.

The announcement of a new purported clean source of energy came at a crucial time: adults still remembered the oil crisis and the problems caused by oil dependence, anthropogenic global warming was starting to become notorious, the anti-nuclear movement was labeling nuclear power plants as dangerous and getting them closed, people had in mind the consequences of strip mining , acid rain , the greenhouse effect and the Exxon Valdez oil spill , which happened the day after the announcement.

Peterson , Fleischmann and Pons, backed by the solidity of their scientific credentials, repeatedly assured the journalists that cold fusion would solve environmental problems, and would provide a limitless inexhaustible source of clean energy, using only seawater as fuel.

Although the experimental protocol had not been published, physicists in several countries attempted, and failed, to replicate the excess heat phenomenon.

The first paper submitted to Nature reproducing excess heat, although it passed peer review, was rejected because most similar experiments were negative and there were no theories that could explain a positive result; [notes 2] [40] this paper was later accepted for publication by the journal Fusion Technology.

Nathan Lewis , professor of chemistry at the California Institute of Technology , led one of the most ambitious validation efforts, trying many variations on the experiment without success, [41] while CERN physicist Douglas R.

Morrison said that "essentially all" attempts in Western Europe had failed. Nevertheless, Fleischmann and Pons and a number of other researchers who found positive results remained convinced of their findings.

The Times called it a circus the same day, and the Boston Herald attacked cold fusion the following day. On 1 May the American Physical Society held a session on cold fusion in Baltimore, including many reports of experiments that failed to produce evidence of cold fusion.

At the end of the session, eight of the nine leading speakers stated that they considered the initial Fleischmann and Pons claim dead, with the ninth, Johann Rafelski , abstaining.

Koonin of Caltech called the Utah report a result of " the incompetence and delusion of Pons and Fleischmann, " which was met with a standing ovation.

Morrison , a physicist representing CERN , was the first to call the episode an example of pathological science. On 4 May, due to all this new criticism, the meetings with various representatives from Washington were cancelled.

In July and November , Nature published papers critical of cold fusion claims. The United States Department of Energy organized a special panel to review cold fusion theory and research.

Nuclear fusion of the type postulated would be inconsistent with current understanding and, if verified, would require established conjecture, perhaps even theory itself, to be extended in an unexpected way.

The panel was against special funding for cold fusion research, but supported modest funding of "focused experiments within the general funding system".

In March Michael H. Salamon, a physicist from the University of Utah , and nine co-authors reported negative results. The lawyer later apologized; Fleischmann defended the threat as a legitimate reaction to alleged bias displayed by cold-fusion critics.

On 30 June the National Cold Fusion Institute closed after it ran out of funds; [71] it found no excess heat, and its reports of tritium production were met with indifference.

Mostly in the s, several books were published that were critical of cold fusion research methods and the conduct of cold fusion researchers.

A review by a cold fusion proponent had calculated "about scientists" were still conducting research.

These small but committed groups of cold fusion researchers have continued to conduct experiments using Fleischmann and Pons electrolysis setups in spite of the rejection by the mainstream community.

A group of scientists at well-known research labs e. Their reported conclusion: no cold fusion. Cold fusion research continues today [ when? The researchers who continue acknowledge that the flaws in the original announcement are the main cause of the subject's marginalization, and they complain of a chronic lack of funding [85] and no possibilities of getting their work published in the highest impact journals.

A pariah field, cast out by the scientific establishment. Between cold fusion and respectable science there is virtually no communication at all.

Cold fusion papers are almost never published in refereed scientific journals, with the result that those works don't receive the normal critical scrutiny that science requires.

On the other hand, because the Cold-Fusioners see themselves as a community under siege, there is little internal criticism. Experiments and theories tend to be accepted at face value, for fear of providing even more fuel for external critics, if anyone outside the group was bothering to listen.

In these circumstances, crackpots flourish, making matters worse for those who believe that there is serious science going on here.

In August , the U. Hagelstein , [91] : 3 and the publication of many new papers, including the Italian ENEA and other researchers in the International Cold Fusion Conference, [92] and a two-volume book by U.

The report was released in The reviewers were "split approximately evenly" on whether the experiments had produced energy in the form of heat, but "most reviewers, even those who accepted the evidence for excess power production, 'stated that the effects are not repeatable, the magnitude of the effect has not increased in over a decade of work, and that many of the reported experiments were not well documented.

While significant progress has been made in the sophistication of calorimeters since the review of this subject in , the conclusions reached by the reviewers today are similar to those found in the review.

The current reviewers identified a number of basic science research areas that could be helpful in resolving some of the controversies in the field, two of which were: 1 material science aspects of deuterated metals using modern characterization techniques, and 2 the study of particles reportedly emitted from deuterated foils using state-of-the-art apparatus and methods.

The reviewers believed that this field would benefit from the peer-review processes associated with proposal submission to agencies and paper submission to archival journals.

Cold fusion researchers placed a "rosier spin" [93] on the report, noting that they were finally being treated like normal scientists, and that the report had increased interest in the field and caused "a huge upswing in interest in funding cold fusion research.

The grant was intended to support research into the interactions of hydrogen with palladium, nickel or platinum under extreme conditions.

Hubler, a nuclear physicist who worked for the Naval Research Laboratory for 40 years, was named director. He claims that the new experiment has already seen "neutron emissions at similar levels to the observation".

Since the Fleischmann and Pons announcement, the Italian national agency for new technologies, energy and sustainable economic development ENEA has funded Franco Scaramuzzi's research into whether excess heat can be measured from metals loaded with deuterium gas.

In —, the ENEA started a research program which claimed to have found excess power of up to percent, and in , ENEA hosted the 15th cold fusion conference.

We can't find any reason to propose more money for the coming year or for the future. In the s India stopped its research in cold fusion at the Bhabha Atomic Research Centre because of the lack of consensus among mainstream scientists and the US denunciation of the research.

Electrolysis cells can be either open cell or closed cell. In open cell systems, the electrolysis products, which are gaseous, are allowed to leave the cell.

In closed cell experiments, the products are captured, for example by catalytically recombining the products in a separate part of the experimental system.

These experiments generally strive for a steady state condition, with the electrolyte being replaced periodically. There are also "heat-after-death" experiments, where the evolution of heat is monitored after the electric current is turned off.

The most basic setup of a cold fusion cell consists of two electrodes submerged in a solution containing palladium and heavy water. The electrodes are then connected to a power source to transmit electricity from one electrode to the other through the solution.

The Fleischmann and Pons early findings regarding helium, neutron radiation and tritium were never replicated satisfactorily, and its levels were too low for the claimed heat production and inconsistent with each other.

An excess heat observation is based on an energy balance. Various sources of energy input and output are continuously measured.

Under normal conditions, the energy input can be matched to the energy output to within experimental error. In experiments such as those run by Fleischmann and Pons, an electrolysis cell operating steadily at one temperature transitions to operating at a higher temperature with no increase in applied current.

Unable to produce excess heat or neutrons, and with positive experiments being plagued by errors and giving disparate results, most researchers declared that heat production was not a real effect and ceased working on the experiments.

Known instances of nuclear reactions, aside from producing energy, also produce nucleons and particles on readily observable ballistic trajectories.

In support of their claim that nuclear reactions took place in their electrolytic cells, Fleischmann and Pons reported a neutron flux of 4, neutrons per second, as well as detection of tritium.

The classical branching ratio for previously known fusion reactions that produce tritium would predict, with 1 watt of power, the production of 10 12 neutrons per second, levels that would have been fatal to the researchers.

Several medium and heavy elements like calcium, titanium, chromium, manganese, iron, cobalt, copper and zinc have been reported as detected by several researchers, like Tadahiko Mizuno or George Miley.

The report presented to the United States Department of Energy DOE in indicated that deuterium-loaded foils could be used to detect fusion reaction products and, although the reviewers found the evidence presented to them as inconclusive, they indicated that those experiments did not use state-of-the-art techniques.

In response to doubts about the lack of nuclear products, cold fusion researchers have tried to capture and measure nuclear products correlated with excess heat.

In the report presented to the DOE in , the reviewers' opinion was divided on the evidence for 4 He; with the most negative reviews concluding that although the amounts detected were above background levels, they were very close to them and therefore could be caused by contamination from air.

One of the main criticisms of cold fusion was that deuteron-deuteron fusion into helium was expected to result in the production of gamma rays —which were not observed and were not observed in subsequent cold fusion experiments.

Researchers in the field do not agree on a theory for cold fusion. This creates a high partial pressure, reducing the average separation of hydrogen isotopes.

However, the reduction in separation is not enough by a factor of ten to create the fusion rates claimed in the original experiment. Electron screening of the positive hydrogen nuclei by the negative electrons in the palladium lattice was suggested to the DOE commission, [] but the panel found the theoretical explanations not convincing and inconsistent with current physics theories.

Criticism of cold fusion claims generally take one of two forms: either pointing out the theoretical implausibility that fusion reactions have occurred in electrolysis setups or criticizing the excess heat measurements as being spurious, erroneous, or due to poor methodology or controls.

There are a couple of reasons why known fusion reactions are an unlikely explanation for the excess heat and associated cold fusion claims.
