RESET Command Guidelines
The following points are guidelines for using the RESET command:
You should use RESET only in interactive sessions. (It functions in the
noninteractive mode, but is more useful in the interactive mode.)
You should use RESET whenever an error or series of errors makes it difficult to
continue compilation.
RESET Command Example
This example shows an interactive session in which a structure is entered incorrectly;
RESET forces DDL to stop parsing that structure so it can be reentered correctly:
