when runs get:

/usr/bin/perl test.pl dbd::sybase::db failed: server message number=1934 severity=16 state=1      line=10 server=bobster\bobster1 text=insert failed because     following set options have incorrect settings: 'ansi_nulls,      concat_null_yields_null, ansi_warnings, ansi_padding'. verify      set options correct use indexed views and/or indexes on      computed columns and/or filtered indexes and/or query notifications      and/or xml data type methods and/or spatial index operations.       @ test.pl line 89. 

now lousy question know. have run same query via 3 different guis sql server , don't error. have gone through first 3 or 4 pages of google results, , have gotten nowhere. information appreciated.

note: assume because query runs in other tools set options correct

please refer this link may need set order create table persisted, computed column, following connection settings must enabled:

set ansi_nulls on set ansi_padding on set ansi_warnings on set arithabort on set concat_null_yields_null on set numeric_roundabort on set quoted_identifier on 

you can set $sth->do() method or isql. need execute them first after connect db, before executing "select", "update" or other command.
