Simplify

Rails
1

Trying to use Eric’s help and Amy Hoy’s page of playing with
auto_complete and decided that the script/console is the place to
rapidly test.

I have this feeling that CONCAT isn’t working for postgresql…

c = find_by_sql(SELECT * FROM clients WHERE CONCAT
(first_name,middle_initial,last_name) = “johnadams”)
^
(irb):61: syntax error
c = find_by_sql(SELECT * FROM clients WHERE CONCAT
(first_name,middle_initial,last_name) = “johnadams”)

^
from (irb):61

As you can tell…I’ve taken a number of stabs at it and simplified it
down as much as I can.

postgresql-7.4.8-1.RHEL-4.1

I can do single field searches and multi-field searches and the
concatenated searches clearly is what I need.

Hi Craig,
CONCAT is actually a mysql function. Sorry about that. For Postgres I
believe you use a || to concatenate.

ex.
SELECT * FROM users WHERE firstname||lastname = ‘EricGoodwin’

Cheers,
Eric G.

The syntax is wrong, you missed off quotes.
c = find_by_sql(“SELECT * FROM clients WHERE
CONCAT(first_name,middle_initial,last_name) = ‘johnadams’”)

See if that works.

perhaps for mysql but CONCAT isn’t syntactically correct for postgresql
as Eric pointed out - which also explains why I couldn’t find any
references for it in my PostgreSQL book too. The || operator worked fine
for PostgreSQL and my only issue remaining is returning the found items
back into the calling code…not a simple matter.

Thanks
