To search for database rows (or files) that contain two or more words in the same sentence (although not necessarily as a sequential string) use a Verity collection, and search for data using the SENTENCE operator. To search for words in the same paragraph use the PARAGRAPH operator. (Applies to:...
CGI variables are special read-only variables made available by ColdFusion. CGI variables include server and browser variables, as well as ColdFusion environmental information. As CGI variable existence is so dependant on external factors (meaning that you'd always have to test for existence before...
(and related and tags) are used to execute stored procedures in ColdFusion (typically when the stored procedures are more complex than can be handled by ). passes parameters in and out of stored procedures. When retrieving variables from a stored procedure the value will be a simple variable unless...
Need a link to allow a user to download an executable file (a Windows EXE file, for example)? Be careful not to place that file in a directory that executes CFM pages or that file could get executed on the server instead of downloaded. Executable files to be downloaded should be placed in their own...
Like many scopes in ColdFusion, COOKIE is a structure. This means that you can use all the Struct functions to access COOKIE variables, and can over COOKIE to iterate through all available cookies. (Applies to: ColdFusion 4 (or later))
The use of session state management, via either CLIENT or SESSION variables, is enabled in the tag. That tag may also be used to set the timeout for SESSION variables, but not for CLIENT variables. If you want to set CLIENT variable timeouts you must do this in the ColdFusion Administrator....
can be used to loop through query results. So can . The difference? executes the loop quicker, but code within it will not be evaluated automatically (unless is used). is thus better suited for looping through queries to be output, is better suited for other forms of processing. (Applies to:...
A ColdFusion variable named user.login is a structure named user containing a member named login. Right? Well, maybe - it depends on how the variable was created. It might indeed be a structure (created using the StructNew() function) with a member with in, or it may be a variable named...
ColdFusion's debugging options include the ability to publish a detailed stack trace for use within structured error handling code. Turning on this debugging option will impact performance and so it should not be enabled unless structured error handling (implemented using and ) is being used....
is used to execute an application (or process) on the ColdFusion server. When using make sure you specify the complete executable file name, including the path and any extension. (Applies to: ColdFusion 4.5 (or later))
