Solution 1

Some of your SELECT statements is returning multiple values. The most likely culprit is that one ending with

JavaScript

AND IESL.Status IN ('1','5')

. However, only you can find out the rogue one.

Use top 1 clause in your sub query to restrict one record at a time Currently your query are like this

SET @Course85=(SELECT CourseName ....)
SET @College85=(SELECT CollegeName FROM CollegeMaster ....)

SET @InspectionDate85 = (SELECT ...)

Change these to by adding Top 1 in each query

SET @Course85=(SELECT Top 1 CourseName ....)
SET @College85=(SELECT Top 1 CollegeName FROM CollegeMaster ....)

SET @InspectionDate85 = (SELECT  Top 1 ...)
