Hmm, the parse is telling you it doesn't know how to express the string
'createdate' as a date or timestamp. Why is that? Because you've
asked it to. I presume the fragments you quote above are part of a
CREATE VIEW statement. You're asking forthe boolean result of comparing
the substring expression to the string 'createdate'. What you probably
want is:
to_date(substr(creat,1,8),'YYYYMMDD') AS 'createdate'
Here's an example of use:
test=# CREATE VIEW quux AS SELECT to_date(substr(creat,1,8),'YYYYMMDD') AS
"createdate", substr(creat,13) AS "User" FROM baz;
CREATE VIEW
test=# select * from baz;
creat
-----------------
200111171623XYX
(1 row)
test=# select * from quux ;
createdate | User
------------+------
2001-11-17 | XYX
(1 row)
