From msdn:

SCHEMABINDING

Binds the view to the schema. When SCHEMABINDING is specified, the select_statement must include the two-part names (owner.object) of tables, views, or user-defined functions referenced.

Views or tables participating in a view created with the schema binding clause cannot be dropped unless that view is dropped or changed so that it no longer has schema binding. Otherwise, SQL Server raises an error. In addition, ALTER TABLE statements on tables that participate in views having schema binding will fail if these statements affect the view definition.
