I have a question about SQL script command..

I have a question about SQL script command.

In order to list all publisher IDs that have published books (only included publishers that HAVE published a book) and each publisher ID should be displayed only once,

what command should I use?

Also the column header should be “Publisher ID”

I think I need to use ‘unique’ command.

Please help!
