Which the new user usually has no access to. And that sp_adduser, for backward compatibility, will CREATE a SCHEMA named after the user and assign that SCHEMA as the user&#39;s default schema. Question was, &quot;does sp_dropuser do the right thing and drop the schema named after the user?&quot;\n<\/p>\n<p>\nShort answer is &quot;yes, it does&quot;. Pretty easy to prove. Actually, sp_adduser can eventually call sp_grantdbaccess and sp_dropuser eventually can call sp_revokedbaccess, so&#8230;\n<\/p>\n<p>\ncreate login bob with password = &#39;A^#DNEfdfhkWD#*iubdwc )000ks1&#39;<br \/>\ngo\n<\/p>\n<p>\nuse adventureworks<br \/>\ngo\n<\/p>\n<p>\nsp_grantdbaccess &#39;bob&#39;<br \/>\ngo\n<\/p>\n<p>\nselect * from sys.schemas&nbsp; &#8212; bob schema is there<br \/>\ngo\n<\/p>\n<p>\nsp_revokedbaccess &#39;bob&#39;<br \/>\ngo\n<\/p>\n<p>\nselect * from sys.schemas&nbsp; &#8212; bob schema is gone<br \/>\ngo\n<\/p>\n<p>\nThe more intriguing thing is&nbsp;when you check this by using the OBJECT_DEFINITION system function:\n<\/p>\n<p>\n&#8212; creates schema<br \/>\nPRINT OBJECT_DEFINITION(OBJECT_ID(&#39;sys.sp_grantdbaccess&#39;))\n<\/p>\n<p>\n&#8212; drops schema<br \/>\nPRINT OBJECT_DEFINITION(OBJECT_ID(&#39;sys.sp_revokedbaccess&#39;))\n<\/p>\n<p>\nSure enough, there is nicely commented code in sp_revokedbaccess to&nbsp;drop a schema.
