I have a table that contains text type information for a given case.  There can be 1 or more text type for a given case.  I am trying to write a query that will return only those case numbers that do not have a text_type of resolution for any of the text types for a given case

 Here is some sample  data

Case_id     Text_Type_Seq   Text_Type        
1                1                           Notes
1                2                           Notes
1                3                           Resolution
2                1                           Notes
2                2                           Notes
2                3                           Notes
2                4                           Notes
3                1                           Notes
3                2                           Notes
4                1                           Notes
4                2                           Resolution


Using the sample data above:

The query should only return

Case_ID
2
3

Since case 1 and 4 have a text type of resolution
