Please help me solve this error.
I'm trying to change the default collation of the database from Latin1_General_BIN to SQL_Latin1_General_CP1_CI_AS.
Msg 1505, Level 16, State 1, Line 5
The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'sys.sysschobjs' and the index name 'nc1'. The duplicate key value is (0, 1, PK_TABLE1).
Msg 5072, Level 16, State 1, Line 5
ALTER DATABASE failed. The default collation of database 'TIOS' cannot be set to SQL_Latin1_General_CP1_CI_AS.
