Re: dbd:Sybase bit scramble

[mje]

Just a small correction to your reference to dbd odbc sql big file blues. I didn't (and I don't think anyone else did either) recommend you used the Easysoft SQL Server ODBC Driver I simply showed you that your code worked with that driver as part of my evidence that something (possibly freeTDS) was broken.

Also, could you point me at this "similar issue was posted on CPAN as a bug for the latest DBC:ODBC".

Oh, sorry I didn't mean to speak for you; I confirm the correction.
link to bug report involving size of insert
Thanks again for the help, I've found it useful.

FWIW I don't think the issue you hit and the one you point to are related. As you may have seen if you looked down the whole log for that bug I rejected it as not a DBD::ODBC but the reporter keeps coming back and reopening it.

$port='...';
$user = "...";
$pass = "...";
$dsn="dbi:Sybase;server=dbhDB;database=...;";
$dbh= DBI->connect("$dsn",$user,$pass) or die "can't connect";


$fileTableName="fileTable";
$cmd="SELECT 1 FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE T
+ABLE' AND TABLE_NAME='$fileTableName\'";
$fetchcmd= $dbh->prepare($cmd);
$fetchcmd->execute();
if(@row= $fetchcmd->fetchrow_array){
        print "the file table is there!!!\n";
}else {
        $createCmd=$dbh->prepare("create table $fileTableName (fileCol
+umn VARBINARY(MAX) not null)");
        $createCmd->execute() or die "can't  create table";
        $createCmd->finish();
}
$fetchcmd->finish();

$insertcmd= $dbh-> prepare("insert into $fileTableName (fileColumn) va
+lues (CONVERT(varbinary(max),?))");
open FILE,"<","./a.b" or die "file";
binmode(FILE);
$filelength = -s FILE;
read(FILE,$fcontents,$filelength);

print"did";
$insertcmd->bind_param(1,$fcontents,DBI::SQL_VARBINARY);
$insertcmd->execute() or print" not ";
$insertcmd->finish();
$sz=length($insert);
print " succeed. size: $sz\n";
close(FILE);

$dbh->disconnect;

results

I probably am missing something obvious here; help will be apprecieated.
