Dynamic SQLJ Execution

If the SQLJ run time fails to load an SQL statement from the module, it calls JDBC to

prepare and execute the statement dynamically. This process is called the default run

time. Figure 1-5 shows the dynamic SQLJ execution environment.

For more information about static and dynamic SQL, see Static and Dynamic SQL on

page 4-1.
