Re: concatenate question - Mailing list pgsql-sql

Thanks so much to everyone for your responses.  You've been very
helpful.  I'm running PostGres 8.4 and we're migrating our datawarehouse
from Oracle 10.2.  I guess datatype is implicitly cast in oracle under
these circumstances:

SQL> create table tony_test as select memberid||addeddate "data" from
TMPSV_PARENT_MASTER where rownum < 5;

Table created.

SQL> desc tony_testName                                      Null?    Type-----------------------------------------
--------
----------------------------data                                               VARCHAR2(59)

SQL> select * from tony_test;

data
-----------------------------------------------------------
