    <p>I have two tables, named:</p> <p>1) item</p> <p>2) bankitem</p> <p>Item has the following fields:</p> <p>ID, CharID, Name, ItemID, Count, Type, ID1, ID2, ID3, Color, Effect1, Effect2, Effect3, LifeSpan, Attribute, Equip, X, Y</p> <p>Bankitem has the following fields:</p> <p>ID, CharID, Name, ItemID, Count, Type, ID1, ID2, ID3, Color, Effect1, Effect2, Effect3, LifeSpan, Attribute</p> <p><strong>Objective:</strong></p> <p>I would like to pull an individual listing (i.e., not just a count) from across these two tables that have the following fields in common: Name, ItemID, ID1, ID2, and ID3 so that I can scan the listing and investigate any duplicate entries, prior to deleting one of them. Every other field could potentially be different based on the nature of how the database is updated.</p> <p>Also, sometimes there may certain records that are okay to have duplicates (again, based on the nature of how the database is used). Is there a way to build into the script to exclude duplicates (based on the above fields) if the field "Name" equals one of the exclusions I could set up?</p> <p>Any help would be greatly appreciated. I am relatively new to SQL queries - I know what I want to do, but am really lost on how to get to the next step.</p> <p>Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
