Previous I wrote blog post about SQL SERVER – Explanation and Example Four Part Name. It was explaining the new feature of SQL Server 2005 of Schema. Few days ago I received email from Chi-Ho, Min of Taiwan, he suggested that he was successfully able to use column without completely specifying all the parts but just using servername…tablename. Please note the three dots (.) between servername and table.
It was interesting what Chi-Ho observed so I decided to share with all of you. Please visit SQL SERVER – Explanation and Example Four Part Name for basic understanding of the four part name. Server, database or owner/schema names are known as qualifiers of the object name. Object does not need to have all three qualifiers when refered. Most of the time objects are refered without servername qualifier as that defaults to local server.
The qualifiders can be omitted by using simple dot too. There are few valid forms of object which are listed here. An object name that specifies all four parts is known as a fully qualified name.
