Does SQL Server 2005 have a geometry data type?
I am trying to figure out to use SQL Server 2005 or Oracle
The primary requirement is to be able to use any GIS software in the = development of a new workflow, to access data, analyze and map data = stored in a database.
The following is what I was able to find on the web.
While both Oracle and Microsoft SQL Server support the storage and = maintenance of geo-spatial information, each vendor has chosen a = fundamentally different approach to the implementation of this = capability.
Oracle has developed a geometry data type that is fully integrated with = the underlying Oracle 9i kernel. Oracle allows users to interact = directly with the database using SQL language. In addition, Oracle has = published the structure of its geometry, making it an open = specification. Any GIS software is capable accessing the data stored in = Oracle. In addition, all business rules for data and geo-spatial data = integrity is built into this model, and any access, input, edits or = other interaction must adhere to the rules that are designed in the = database no matter the application accessing the database.
Conversely, Microsoft has not developed a geometry object in SQL Server. = Each GIS vendor is therefore responsible for developing a method for = storing GIS information in this database. Thus, Intergraph, ESRI, and = MapInfo have developed their own binary geometry structures to allow = them to store geo-spatial information in SQL Server. This approach makes = the geo-spatial information dependent on the GIS software that is used.
Can anyone please help me!

There is no specific datatype. That doesn't prevent you storing
geo-spacial data as your post explains. You can define your own complex
datatypes in SQL Server.

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.

--|||I've never heard of a geometry data type. ESRI's products do run on
SQL though - SDE is the one that comes to mind. You can use SQL if
you're using ESRI....see esri's site:
