Re: How to define + operator for strings

So is the best way to create function CONCAT(s1, s2, ... s10) which returns
concatenation in its arguments in both DBMS.
So I can use CONCAT() instead of  plus operator.

I'm using Microsoft Visual FoxPro.
It allows date+integer and timestamp+integer arithmetics.
In first case integer means number of days and in second case number of
seconds.

SELECT DB||CR FROM OPER

causes error message

Command contains unrecognized phrase/keyword.

There was never problems in date+integer arithmetics in Visual FoxPro.

Visual FoxPro has powerful embedded GUI report designer and grid control.
I haven't found any comparable which works with Postgres.

So I select data from Postgres, store it in FoxPro local data engine and
create reports from it.
