BUG #: 57437 (SQLBUG_70)
A SELECT statement that joins several tables (typically, approximately 32) may cause the client application to stop responding (hang) or to return one of the following error messages.

This error message may appear in an ODBC application:
[Microsoft][ODBC SQL Server Driver]Protocol error in TDS stream
[Microsoft][ODBC SQL Server Driver]Function sequence error
This error message may appear in a DB-Library application:
DB-Library: Possible network error: Bad token from SQL Server: DataStream processing out of sync. Net-Library error 0: (null)
DB-Library: DBPROCESS is dead or not enabled.
An application that uses the OLEDB provider for SQL Server (SQLOLEDB) may not return any error; however, it may appear to the application that the query returned no rows even though the query did produce one or more rows.
To resolve this problem, obtain the latest service pack for Microsoft SQL Server 7.0. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:
301511 INF: How to Obtain the Latest SQL Server 7.0 Service Pack
NOTE: The following hotfix was created prior to Microsoft SQL Server 7.0 Service Pack 4.

The English version of this fix should have the following file attributes or later:
   Version       File name       Description   -----------------------------------------------   7.00.1018     Sqlservr.exe    SP3-based hotfix				
NOTE: Because of file dependencies, the most recent hotfix or feature that contains the preceding files may also contain additional files.

To possibly prevent this problem from occurring, increase or decrease the number of tables referenced in the query. For example, you might be able to avoid the problem by adding a self-join that does not affect the data returned from the query (join a table to itself on the table's primary key columns).
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft SQL Server 7.0 Service Pack 4.
