Row-Level Security Set for SQL Server
Microsoft architect James Hamilton discusses upcoming security changes in the next release of SQL Server, code-named Yukon.Last month, I met with Microsofts James Hamilton, an architect of Microsoft SQL Server, to be briefed on upcoming security changes in the next release of SQL Server, code-named Yukon, which is expected to begin beta testing in the first half of next year. The most significant security change in Yukonand one that hadnt been mentioned to the press previouslyis that SQL Server will support a declarative security model that provides much finer, more flexible security controls than are possible using the SQL table- and view-based permissions model.
"What were building here is a row-level security," said Hamilton, in Redmond, Wash. "Every user accessing a table has a predicate assigned to them that controls their access. That predicate gets applied to every query; same thing with an update. Unless youre updating your particular row, it will fail."
