SQL Server 2008 R2创建圈

Question

I am using SQL Server 2008 R2 and I would like to use CIRCULARSTRING to draw a circle. I could use the POINT and STBuffer but then the circle is filled with a color, while I want the outline. Trying to use the CIRCULARSTRING I get an error message:

label CIRCULARSTRING(2 0, in the input well-known text (WKT) is not valid. Valid labels are

So I read that this is a feature in SQL Server 2012.

My questions:

1. Is there a way to draw the outline of a circle in SQL Server 2008 R2?
2. Can I update SQL Server 2008 R2 to include this feature?
3. If I upgrade to SQL Server 2012 will it be compatible with VS2008 SSRS?

Thanks

Answer 1

This function is presented in SQL Server 2012 (see link below).

1. You can create custom function to calculate coordinates of point on the circle. It can be TSQL (not sure you can do it) or clr (sure this is better way).

2. No.

3. No.
