问题 I am on PDI 7.0 and have a "Modified Java Script Value" step inside a transformation as below: var numberOfDays = 100; Alert(numberOfDays); setVariable("NUMBER_OF_DAYS", numberOfDays, "r"); Alert(getVariable("NUMBER_OF_DAYS", "")); However, when I run the transformation, the first Alert correctly throws 100, but the next Alert is blank (meaning the variable is not set). What is wrong here? 回答1: As a rule of thumb , you should never set a variable and read it within the same transformation .

问题 How can I append two (maybe more) XML files? I search for those files using the 'Get File Names'. If more than one file is found, how can I append their content, to result in just one XML file?

问题 I'm developing an ETL and must do some routines for monitoring it. At the begining, I must make in INSERT on DB to create a record informing the filename and starting process datetime. This query will return the record's PK and it must be stored. When the ETL of that file finishes, I must update that record informing the ETL finished with success and its ending process datetime. I use Text File Input to look for files that match its regex, and add its "Additional output fields" to stream. But
