Why do I get the symbol data link in the query_name of the data model

329555Oct 14 2002

If I use an inline subquery within the SELECT of a data model query, the symbol data link appears in the query_name of the data model.
This causes the data link between two queries not to be used even if there is an existing link between the two. The trace file doesn't
have that join condition and so the child query in which the inline subquery was added fetches many redundant data.

Any idea what that symbol represents and how to get rid of it. It also appears during other times, not only when we use inline subquery
within a SELECT. Not sure if it can cause any harm to the report.

The problem is seen in Report Builder 6.0.8.19.0. Not sure if the problem is with other releases also.

Any suggestions are welcome.
