A string containing the name of the user account to be deleted.

<div class="refsect2">
<span class="refsect2title">cascade – </span>
This flag (0/1) specifies whether to delete the stored procedures/functions, PL modules,
tables and user defined types owned by the user. It cannot drop assembly definitions (created with
CREATE ASSEMBLY), because CREATE ASSEMBLY is a database wide operation (done by the DBA group) so the
assembly has no owner (since you can not drop DBA). The default value is zero. Sometimes it is not
possible to drop the resources, for example if a table owned by the user is referenced by foreign key
in a table that would not be dropped. The drop user will detect that and will print the appropriate
error message (giving up the operation).
