Description:

SELECT '2014-03-26'::DATE AS date1, '2014-03-26'::DATE AS date2

returns 2456597 2456743

I don't understand these return values.

first is 2013-10-31 and second the correct 2014-03-26

same with 2014-03-27 or all other dates is working

I cannot reproduce that failure here:

test=> SELECT '2014-03-26'::DATE AS date1, '2014-03-26'::DATE AS date2;
date1 | date2
------------+------------
2014-03-26 | 2014-03-26

The BASIS Company checks if it is a problem in the Interpreter.

In Delphi we cannot reproduce the error via ODBC
In Business Basic the date was represented as a 4-byte Julian date with the reported error.

I will report if I have new findings

I just found the problem:

The returned data was converted from 8859-1 to cp850 without caring about the data types :(

Georg is mentioning ODBC in the subject. If it could be possible to
get the code sample used with it it would be nice. Perhaps this is
simply a driver issue.
