Re: problem with select into and timestamp.

To case text to timestamp is not a problem,
so you can use:
......
text(mst_date||' '||mst_time)::timestamp,
text(mst_date||' '||mst_time)::timestamp,
......
to get around this!

yes, that's what I want, but I get another error... here's my sql.

insert into document_status
(
version,
cdate,
mdate,
filename,
direction,
partner,
msgtype,
docref,
status,
statusdesc,
unit
)
select
1,
(mst_date||' '||mst_time)::timestamp,
(mst_date||' '||mst_time)::timestamp,
mst_filename,
mst_direction,
mst_partner,
mst_msgtype,
mst_docref,
mst_status,
mst_statusdesc,
mst_unit
from ectmst

the only trouble is I get a cast error.

ERROR: Cannot cast type 'character' to 'timestamp with time zone'.

I suppose this is because the date and time fields were previously character
( TEXT ) fields.....

is there a way around this?

many thanks

Geoff

I hope this is what you want:

urldb=# create table foo(d date,t time);
CREATE
urldb=# insert into foo values(CURRENT_DATE,CURRENT_TIME);
INSERT 97260539 1
urldb=# select * from foo;
d | t
------------+-----------------
2002-08-09 | 11:20:12.214437
(1 row)

urldb=# create table foobar (newdate timestamp);
CREATE
urldb=# insert into foobar(newdate) select (d||' '||t)::timestamp as newdate
from foo;
INSERT 97260628 1
urldb=# select * from foobar;
newdate
-------------------------------
2002-08-09 11:20:12.214437-07
(1 row)

urldb=# \d foobar
Table "foobar"
Column | Type | Modifiers
---------+--------------------------+-----------
newdate | timestamp with time zone |

I've got a small problem with "select into".

I've got an old table with date and time as seperate text columns.
I want to insert these into a new table into 1 column as timestamp
format.
I spent this morning looking at the 7.2 docs and spent ages working on
something that's not supported (i.e. the timestamp (date '2002-08-09',
time
'11:29:00') ) function...arg!

could someone show me the light on how I can get this working correctly
and
make my day easier.

many thanks

Geoff
