When I try to edit table data in SQL Server Management Studio 2008 R2 (right click in table object, Edit Top 200 rows) I receive this error: "Invalid prefix or suffix characters. (MS Visual Database Tools)".
This happens when you try to edit the top 200 rows of a SQL Server 2012 database using the 2008 R2 SQL Server Management Studio. Upgrade SQL Server Management Studio to 2012 or edit the rows using a SQL query.
