Roy,

I had different output when I ran your query:
_NAME= replace(cast(_NAME as nvarchar(255)),char(13)+char(10),':'),
_NAME= replace(cast(_NAME as nvarchar(255)),char(13)+char(10),':'),
_NAME= replace(cast(_NAME as nvarchar(255)),char(13)+char(10),':'),
_NAME= replace(cast(_NAME as nvarchar(255)),char(13)+char(10),':');

It looked like select statement output with 17 rows (17 columns in the
table) like the above. No UPDATE or SET function.
