When the consolidated database is SQL Anywhere (version 10 or later) or Microsoft SQL Server (2005 or later), the default
isolation level for downloads is snapshot isolation. If the consolidated database is an earlier version of these databases,
the default download isolation level is read committed.
You can also change the default isolation level in a script. However, for SQL Anywhere version 10 and Microsoft SQL Server
2005 and later databases, the isolation level is set at the start of the upload and download transactions. This means that
if you set the isolation level in the begin_connection script, it may be overridden in the begin_upload and begin_download
This option only applies to SQL Anywhere version 10 and Microsoft SQL Server 2005 consolidated databases.
