I have a scenario where two tables are in a One-to-Many relationship
and I need to move the data from the Many table to the One table so
that it becomes a One-to-One relationship.
I need to salvage the records from the many table and without going
into detail, one of the reasons I can't do the opposite as
there are records in the ONE table that I need to keep even if they
don't have any child records in the MANY table.

i need to update a column which is a member of the PK on this
table. there are some thousands of rows to be updated, many more
thousand already in the table.
so, i get a constraint violation doing a simple
set col1 = 'x' where col1 = 'y'
attempted (in general terms; col1 & col2 are the PK)

The initial row is inserted with the colPartNum column containing a valid
LIKE pattern, such as (without the single quotes) 'AB%DE'.
I want to update the column value with the results of a query against a
different table (that uses the LIKE predicate) but cannot get around the
SQL0132 error .
I have tried the hex notation after the LIKE such as (without the
quotes)...
" where colNewPartNum like ( X'27' || nnn.colPartNum || X'27) " ,...

I know I can use Inner Joins in an Update query like this:
UPDATE DISTINCTROW tblA INNER JOIN qryA ON tblA.SomeID = qryA.SomeID SET
Flag = 0
WHERE (Flag = -1);
But I am specifying the new value to overwrite the old value, and just using
the join to narrow the set. If I don't know the new value and need to
select it from another unrelated table with no unique ID, can I still use an
update query?

This control also includes a textbox which the user can input a value.
These two columns are side by side and not in a vertical layout.
