You are trying to add, drop, or modify a constraint on a table that has a schema stability lock (LCK_M_SCH_S or Sch-S) held on it. The schema stability lock is not compatible with DDL. The lock may be held by a query involving this table that is taking a long time to compile.
You are trying to add, drop, or modify a constraint on a table that has a schema stability lock (LCK_M_SCH_S or Sch-S) held on it. The schema stability lock is not compatible with DDL. The lock may be held by a query involving this table that is taking a long time to compile.
Wait until no queries which access this table are compiling, then retry your DDL.
For more information on the schema stability lock, see the Books Online topic "Understanding Locking in SQL Server".
