Hi, I have Cognos 7.0 Impromptu reports and these reports have been created with the Mainframe datasource. Now the business needs these reports should be upgraded but with Oracle datasource. So what's the idea, first we should migrate these reports into ReportNet? then in that case what we will do with the Impromptu Catalog? Second, suppose we need to migrate these reports into Cognos 8 (may be 8.4) then how we will do that? do we need to create a FM Model for these reports. Please advice!
SET is the ANSI standard for variable assignment, SELECT is not. SET can only assign one variable at a time, SELECT can make multiple assignments at once. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one) When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value) As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
