TDbf - a problem with filtering numeric fields
«
on:
March 11, 2008, 11:28:29 pm »
I have found that I cannot apply a filter expression for numeric fields, like ftFloat, ftInteger, if it contains a "minus" sign.
Like
Code:
[Select]
MyTable.Filter := 'fieldFloat = -10.00';
assuming that fieldFloat has ftFloat type.
The program returns an error message:
Index based on unknown field "-"
The expressions like
fieldFloat = 10.00
fieldFloat >10.00
fieldFloat <10.00
work just fine.
Any ideas how to solve this?

Hi,
You are right, it doesn't work. TDBF parser seems to parse C/C++-like operators (&&, |, =!) but ignores a minus sign before a number.
I suggest you to open a bug report.
Regards,
Gerard

Ok, the bug report is submitted.
So far I have found one funny workaround for the problem:
instead of using the obvious form "field=-10.00" one can set up "field=0-10.00" and this will work. :lol:
