is it possible to convert character fields to character varying using
this is my case:
I have a table with character fields:
CREATE TABLE c1 (name char(20), date char(20));
INSERT INTO c1 VALUES ('a',a');
INSERT INTO c1 VALUES ('b',b');
and another table with character varying fields:
CREATE TABLE v1 (name varchar(20), date varchar(20));
when I dump c1 and restore it to v1 my selections on v1 are failed
because the data on v1 table contains trailing spaces.
SELECT * FROM v1 WHERE name ='a'; (failed)
if I alter types on v1 to character and then back to character varying
the trailing spaces disappears and the above selection is ok.
Is there any other way to clear trailing spaces when I restore the table?
