arcgis javascript api - Convert spatial Geographic data from sql server 2008 to Json

Is there any example to convert spatial data (point,line,polygon) stored as geographic in sql server 2008 into Json and display data using Arcgis Javascript Api 3.0.I have tried converting geographic data into Json given Geometry to Json but as my data stored in geographic data format it failed.Thank you in advance.

Answer

In theory just replace all SQL commands having geometry:: cast to geography casts (assuming that you 2008 R2 MSSQL server) Edit: looked that example code . Change Microsoft.SqlServer.Types.SqlGeometry to Microsoft.SqlServer.Types.SqlGeography OR Find SQL command which select code and force it to cast your geography objects to geometry
