6.4 OMITNOTNULL | INCLUDENOTNULL
Use OMITNOTNULL
and INCLUDENOTNULL
to omit or include the words NOT NULL
for columns that cannot contain null values. Assuming the column cannot be set to null, DDLGEN
outputs the following definitions:
-
If
INCLUDENOTNULL
(or nothing) is specified:COL CHAR (10) NOT NULL
-
If
OMITNOTNULL
is specified:COL CHAR (10)
The default templates for each supported database already include the correct setting for this argument.
