Backend-Crash

Hi all,

the following query, used in a perl-script, kills the backend -
but works when offered through "psql":

$query = "SELECT count(bk_vk_dem), to_char(sum(bk_vk_dem),'999999D00')         FROM   ccbooked         WHERE
bk_kartentyp= " . $kartenid[$i];
 


My configuration:
- DBI-1.13
- DBD-Pg-0.93
- SuSE-Linux 2.2.14
- PostgreSQL 7.0.2
- gcc 2.95.2

Any clou?

Thanx in advance-Rolf
