Multiple Sorts in ColdFusion Report Builder
Posted on 2007-04-02
I'm trying to build a report that allows the user to select the sort order. I was able to do this in Crystal Reports by using several sort fields and moving data into them as needed to satisfy the requested sort. I would always sort on all the fields, but sometimes the fields would be blank and therefore basically ignored. For example, I want to allow the user to sort by year, location and SSN, or by year, location, and name. Year and location were database fields and always populated, whereas SSN and name were calculated fields. I would populate either SSN or name only if that was actually to be used in the sort, otherwise it would be blank.
I tried this in Report Builder using the advanced option in the query builder. I entered the 2 calculated fields into the order by statement, it was even nice enough to show the calculated fields in a dropdown box. However, when I tried to preview the report I got an error "Table or alias not found: calc -- Location of error in the SQL statement is: 119 ".
Should this approach have worked? Is there another way to accomplish this?
Also, is there a way to look at the code that the preview is trying to execute? The only code I've found is the code snippet, and the code fragments in the fields and parameters.
