Smartlist generator question
« on: September 12, 2008, 11:31:14 pm »

I had a playlist called Incorrect Rating that would show me where [Rating] != [Ben's Rating].  That doesn't work so I had to elaborate with all the options: R =1 & B != 1, etc... so 10 total comparisons.  When I opened to edit it and only added a SORT item, it stopped working.  Now I can't get it to function at all.

Is there a way to make [Rating] != [Ben's Rating] work??  Seems so simple in SQL!

I had a similar question recently solved by Marco. I think it's what you're looking for...

[=isequal([Rating],[Ben's Rating],1)]=0

I have zero experience with SQL, but I'm guessing that "!=" is SQL speak for "is not equal to"

[=isequal([Rating],[Ben's Rating],1)]=0 might be more reliable if you use a numeric compare for equality, rather than a case-insensitive string compare...

[=isequal([Rating],[Ben's Rating],2)]=0

A full list of isequal compare types can be found in the wiki, here. I see that page I created has just shy of 6000 views so far... hopefully some of those 6000 have found the information helpful.

This is so close to exactly what I need.  The problem is that using those, items that haven't been set yet, [Ben's Rating] = [] and [Rating] = ?, they don't line up as identical.  So null is not equal to ?, which is the Rating's null value.  How can I force convert these two items to integers?  Is there an int or integer function?  Could probably be placed right in the isequal function for simplicity.

I can make it work with a bunch of extra junk comparing rating & ben's rating but it gets hectic.  Any other solutions to this problem welcome!

Simply taking what was said above, which almost works, and adding this would probably work:

-[Rating] = ? OR -[Ben's Rating] = 0

How can the above be converted to working MC query code?

How can I make this work as expected?  The problem is that 0 is not equal to ?.  Rating defaults to ? and [Ben's Rating] defaults to 0 (integer).  So comparing direct equality would work except for this.  So the thinking is that if AT LEAST one of the two fields are essentially = 0 (aka ?), then it would eliminate the cases where they both equal their zero value.

If Rating = ? & Ben's Rating = 0, without this, the items would be returned (bad).

Now apply the above constraint... [RATING] != ? OR [BEN'S RATING] != 0 ... it would fail because [Rating] = ? (not !=) and [Ben's Rating] = 0 (not !=).

XOR (exclusive or) would break it a bit because then it wouldn't return changed values.  It would show initially rated songs [Rating]=5 & [Ben's Rating]=0...but if I updated Ben's Rating, and then changed Rating, it wouldn't bring it up...

I'm finding it really hard to follow what you're doing, but, when using expressions, to get the same list as: [rating]=[], you have to use isequal([rating],? stars)
Simply taking what was said above, which almost works, and adding this would probably work:

-[Rating] = ? OR -[Ben's Rating] = 0

How can the above be converted to working MC query code?
(-r=[] or -[Ben's Rating]=0)

You could change all the values for [ben's rating]=0 to ? stars and that should cause them to behave as expected with the original expression based query?
