Kenneth Fisher warns that you should specify schemas in scripts:
But why? I mean the table gets created either way and since the default is dbothere is no real reason to name it.
Actually no. The default is not in fact dbo. It frequently is dbo but by no means always. The default schema is part of your USER information. Specifically theDEFAULT_SCHEMA option. Well, unless you are a sysadmin. Then it actually does always default to dbo.
Schemas are a very powerful grouping mechanism, and they’ve been around long enough that if you aren’t taking full advantage of them, you really should.
