Thanks for the feedback folks.  I'm inclined to agree that this is a bug.  I have found the conflict with the two tables.  
Table one:  sc_cat_item, which has a field called delivery_plan_script
Table two:  sc_cat_item_delivery_plan, which has a field called script.
Obviously this becomes ambiguous when concatenating these together using "_" as the separator.  
Since this is an existing platform and application, this isn't something I can just randomly change in my schema.
Looks like the last update to the referenced bug was in September of 2018 (this year).  
Any thoughts on when a fix for this might be made available?  This prevents me from being able to progress my consideration of using MonetDB in my environment.   
Thanks,
 - Herman

Hi,

Internally (as in in the MonetDB code base),
the impact of the problem could imho be significantly reduced (though not fully avoided)
by "simply" using different separator characters (or even strings?) when creating qnames,
e.g. schema:table;column instead
of    schema_table_column ...

A unique bijective reversible mapping from schema,table,column to qname should avoid the problem entirely , but might require to use separator chracter(s) that are not valid in SQL identifiers, if such exist ...

Best,
Stefan

Hai Herman,

This is because something has already been defined before, whose complete qname is “zboot_sc_cat_item_delivery_plan_script”.  This often happens with (but probably not limited to) schema_name+table_name+column_name.  In MonetDB test suite, we have two examples to trigger this (type of) error:

sql>create table foo (id integer, bar_id integer);
operation successful
sql>create table foo_bar (id integer);
CREATE TABLE: sys_foo_bar_id conflicts

and

sql>create table foo_bar (baz int);
operation successful
sql>create table foo (bar_baz int);
CREATE TABLE: sys_foo_bar_baz conflicts

This is not a bug.  You need to change your table and/or column definitions, like your alternatives below.  Then CREATE TABLE will succeed.

Regards,
Jennie
