I have a 3rd party software that submits information to my database in a table called call_results. The problem is that it submits the date to one column(calldate) and the time to another (start_time). The reports that i need to run, go significantly faster if date and time are in one column.
--this is what he submits to me
insert
into call_results (phonenum, callnum, calldate, start_time)values ('5552552555', 4524, '6/24/2002', '17:00:32')
To get around this i have tried to create the following.
CREATE TABLE "call_results_fixed" (
"id" int8 DEFAULT nextval('"call_results_fixed_id_seq"'::text) NOT NULL,
"callnum" int4,
"calldate" timestamp,
"phonenum" varchar(15),
"start_time" timestamp
CONSTRAINT
"call_results_fixed_pkey" PRIMARY KEY ("id")) WITH OIDS;
CREATE VIEW "call_results" AS SELECT * from call_results_fixed
CREATE
RULE ins_call_results AS ON INSERT TO call_results DO INSTEAD INSERT INTO call_results_fixed (calldate, callnum, phonenum, start_time)
VALUES ("timestamp"(new.calldate), new.callnum, new.phonenum, "timestamp"(((to_char(timestamptz(new.calldate), 'MM-DD-YYYY'::text) || ' '::text) || text(new.start_time))));
This would effectivly concatinate the date and time and insert them into the call_results_fixed table. (or so it would seem)
I get an error when i set this up, however that says
"Bad timestamp external representation '17:00:32'
In other words, it seems that it is testing the column type without taking into account the rule.
I have tried to work around this by creating a table called call_results with start_time being just a time field and creating similar rule on the table call_results. With this senario I have problems with the select do instead rule.
**whew!** Does that make sense?
Thanks in advance for reading my epic novel, and for any help you can give.
