Can anyone assist with situation when DB2 view has "valid=N", so after issue 'drop' command?
DB21034E  The command was processed as an SQL statement because it was not a
valid Command Line Processor command.  During SQL processing it returned:
SQL0204N  "My_view.Name" is an undefined name.  SQLSTATE=42704.
Looking for the way that doesn't require recreate parent to this table.

Hi sevior,

Breaking this down:

DB21034E  The command was processed as an SQL statement because it was not a
valid Command Line Processor command.  During SQL processing it returned:

Just informative.  Nothing to read there.  :)

SQL0204N  "My_view.Name" is an undefined name.  SQLSTATE=42704.

In this message, "My_view" is actually the schema name (though case should not be an issue) and "Name" is the view name.  It sounds like you're expecting something else.

This command will list all views that are invalid
db2 "select viewschema.viewname from syscat.views where valid = 'N'"

This command will drop all views that are invalid
db2 -x "select 'db2 -v drop view '|| rtrim(viewschema) || '.\' || '\"' || rtrim(viewname)|| '\' || '\"' ||'' from syscat.views where valid = 'N'"

Modify these commands to your needs (if you want to say drop a specific view ).
