What are your previous/following lines on that code? I'de like to see it more
complete in order tyo find possible errors. I've used perl to manage really
large tables (much larger than yours) with no problem. Also, which
database/driver are you using?

Subject: select statement fails
greetings all,
I think I have a case of too much data being returned to a perl script, but
I'm not certain.
using perl 5, DBI:ODBC, MS-SQL and IIS 6:
executing the following code:
$sth = $dbh->prepare("select field1 from table ") || &failed( "prep failed" );
$exec = $sth->execute() || &failed( "exec failed" );
correctly returns 170 rows of data. but if I replace the field name with *,
as in:
$sth = $dbh->prepare("select * from table ") || &failed( "prep failed" );
$exec = $sth->execute() || &failed( "exec failed" );
it returns no data, but neither does either statement fail. the table
contains 160 fields.
can the script be overwhelmed with too much data, and/or are there limits of
field counts or return-set size, and if so can they be managed? I have a hard
time believing perl can't handle this table.
any ideas greatly appreciated. thanks.
