XML in SQL Server - Indexes

You MUST add indexes to an XML column in SQL Server. If you don't do that, queries will soon become very slow. Just run these statements:


CREATE PRIMARY XML INDEX primaryidx ON [table](XmlColumnname)
GO


CREATE XML INDEX pathidx ON [table](XmlColumnname)
USING XML INDEX  primaryidx  FOR PATH
GO


CREATE XML INDEX valueidx ON [table](XmlColumnname)
USING XML INDEX  primaryidx  FOR VALUE
GO


CREATE XML INDEX propidx ON [table](XmlColumnname)
USING XML INDEX  primaryidx  FOR PROPERTY
GO
