Application Programming Guide and Reference for Java
v When the application executes positioned UPDATE and DELETE statements
with the iterator, those changes are visible to the iterator.
v When the application executes INSERT, UPDATE, and DELETE statements
within the application but outside the iterator, those changes are visible to
the iterator.
The value for dynamic must be true or false. The default is false.
DB2 Database for Linux, UNIX, and Windows servers do not support dynamic
scrollable cursors. Specify true only if your application accesses data on DB2
for z/OS servers, at Version 9 or later.
For connections to IDS, only false is supported. IDS does not support
dynamic cursors.
For an iterator, specifies the columns that are to be modified when the iterator
is used for a positioned UPDATE statement. The value for updateColumns
must be a literal string that contains the column names, separated by commas.
For an iterator, specifies a column of the result table that is to be updated
using the iterator.
For an iterator or connection context, specifies a Java variable that identifies a
user-defined attribute of the iterator or connection context. The value of
Java-constant-expression is also user-defined.
For a connection context, specifies the logical name of a separately-created
DataSource object that represents the data source to which the application will
connect. This option is available only for the IBM Data Server Driver for JDBC
and SQLJ.

setting for holdability.
