SAVEPOINT
The SAVEPOINT statement is used to identify a point in a transaction to which you can later roll back.
General format
EXEC SQL [ AT Database ]
 
  SAVEPOINT Savepoint-Name
 
END-EXEC
Syntax rules
1. Savepoint-Name is Nonnumeric Literals, as defined in the Definitions section of the Preface of this document.
General rules
1. Database identifies the active connection that will execute the query and must be previously defined using a Format 4 DECLARE statement. By default, when the AT clause is used, the active connection is switched to the connection identified by Database and all the next statements will work on that connection; under the -csora option, instead, the connection is switched only for the current statement.
2. Savepoint names must be distinct within a given transaction. If you create a second savepoint with the same identifier as a previous savepoint, then the previous savepoint is erased.
Examples
Define a savepoint named SP1
exec sql
     savepoint sp1
end-exec
