DB21034E The command was processed as an SQL statement because it was
not a

returned:

The error means that you are trying to assign a set of values to the column:

but you need a scalar value ( a single value, not a set of values ). You
can solve this by adding a where clause in the subselect as:
UPDATE D1.TCEOSURROGAT TCEOSURROGAT_1
SET UPDSURRUSR = (
SELECT
CASE
WHEN LOCATE('*',STRIP(SURRUSR)) <0 THEN REPLACE(SURRUSR,'*','%')
WHEN LOCATE('%',STRIP(SURRUSR)) <0 THEN REPLACE(SURRUSR,'%','_')
ELSE STRIP(SURRUSR)
END AS NS
FROM D1.TCEOSURROGAT TCEOSURROGAT_2
WHERE TCEOSURROGAT_1.<p.k= TCEOSURROGAT_2.<p.k>
)
Since I dont know what column(s) that is the key in D1.TCEOSURROGAT I
used <p.kas a marker
