here is example
table name is "mail":
column | type
-------------------------
sender |char
subject |char
content |bytea
I want copy some record into new table 'mail_new'.
sql:
create table mail_new as select * from mail sender='dennis'
result has an error:
operator does not exist: text || bytea
But if my sql statement has no column "content"
the sql works.
sql:
create table mail_new as select sender,subject from mail sender='dennis'

Quoth dennis <den...@teltel.com>:
I need to copy some data to new table.
But I encounter some error message.
the table structure
Table A:
c1 char
c2 bytea
Table B:
c1 char
c2 bytea
My sql command:
insert into B as select * from a where c1=xxx
'AS' isn't valid there. What is xxx? Is it a field you haven't shown us,
or is it a quoted string?
error:
operator does not exist: text || bytea
That command (with 'xxx' quoted and the AS removed) doesn't give that
error with those table definitions, so you will need to show us your
actual query.
