chained and unchained transaction mode
A chained mode transaction may be thought of as “auto-starting”; when you log in and begin any SQL statement, ASE invisibly begins a transaction which will continue until you explicitly end it. In this way, you are always making all changes as part of a transaction.
In unchained mode, the rule shift in an important manner: while any single data change statement is treated as a transaction, group of statements are not transactions without an explicit command to begin a transaction.
