SSRS 2008: Get specific row value from DataSet2 based on calculated value in DataSet1

Question

I have two Datasets. The first is used to populate a tablix. In that tablix, there is a calculated percentage field. I want to show a different background color based on whether the percentage is in a certain range, in other words, based on KPI thresholds. I have the thresholds coming in dynamically in a second dataset, that hold ColorName, LowerLimit, and UpperLimit fields. I know I need to use some sort of lookup function to get the row's color value where the percentage falls within the LowerLimit and UpperLimit for that row. I can assume that the Limits will not overlap. Any function/approach that will accomplish this? The reason I am pulling it dynamically is to give the customer a way to configure the thresholds, (using a maintenance screen that will manage that table). Thanks!

Answer 1

返回sql并在数据集中添加另一个字段，以便阈值位于tablix使用的数据集中
