I'm using Oracle SQL and I need to ensure all my items are located in exactly 5 specific locations like below. My SQL is not good enough to get the correct syntax. The issue I face is that my items are located in only few of the 5 locations and I need to find the missing ones which i will use to upload manually into the database.
This is what I am hoping to achieve for all my items in exactly these locations.
Issue is that the database table has many locations but I need to find only those records where the item is missing in any of the 5 specific locations, the 5 specific locations being Austin, Boston, Chicago, Dallas and Houston.In the below screenshot, the ones in red are what im trying to obtain via an SQL.
Below is what I want the SQL to output. As mentioned above, once I find the missing records, I will manually upload them into the database. Any help with the SQL will be gladly helpful. Thanks in advance
