SAVE Command
SAVE Command
The SAVE command instructs the DDL compiler to save (or purge) the currently open
dictionary when the dictionary is closed.[
SAVE
directs the DDL compiler to save the currently open dictionary when the dictionary
is closed. SAVE is the default.
NOSAVE
directs the DDL compiler to purge the contents of the currently open dictionary
when the dictionary is closed. The NOSAVE command is ignored if the dictionary is
part of a Pathmaker project.
SAVE Command Guidelines
The following points are guidelines for using the SAVE command:
•
SAVE, and its inverse NOSAVE, are in effect only when DDL closes a dictionary.
An open dictionary is closed automatically when compilation terminates; it can also
be closed with the NODICT command or by opening another dictionary with the
DICT command.
•
If an existing dictionary is opened for update and NOSAVE is in effect when the
dictionary is closed, the contents of the dictionary are purged. The NOSAVE
command is ignored if the dictionary is part of a Pathmaker project.
•
If the DDL compiler encounters an error while processing a statement that
describes a DDL object, it does not add that object to the dictionary. If the
dictionary is saved (either by default or because of an explicit SAVE command), it
does not contain all the DDL objects specified in the source schema.
•
You can use the NOSAVE, ERRORS, and SAVE commands to ensure that a
dictionary is saved only if the entire source schema is compiled without errors in
one of two ways, as follows:
°
Put a NOSAVE command and an ERRORS 1 command at the beginning of the
source schema.
°
Put a SAVE command at the end of the source schema.
•
If the DDL compiler encounters an error, compilation terminates while NOSAVE is
in effect, and the dictionary is not saved. The dictionary is saved only if compilation
completes with no errors; thus, the dictionary either contains all the requested
objects or it is purged.
