Memory not being freed with DBD::ODBC
I have the following script (extremley simplified) foreach my $key (sort {$a=$b} keys %run){ my $inp; $inp=$dbh-selectall_arrayref(select id, [description] from Kaonix_import_base where idint between ? and ? ,undef,$run{$key}-[0], $run{$key}-[1]) ; addrec($inp); -- sub to run very heavy regexs against the select and insert into another table undef($inp); } The problem is that memory is not being freed against the statement handle on each iteration and eventually the script stalls due lack of memories any ideas?
Issue with DBD::ODBC (SQLServer) and bcp
Hi Is it a known issue with running bcp while an active db connection I have a script that basically opens a db connection selects some data parses/transforms the data writes to a text file -- runs bcp to import the data into same database -- does some updates in SQLServer The issue is that if I dont disconnect before running bcp, the op just hangs (with no output). If I disconnect before bcp and then reconnect everything is fine. Is this a known issue Platform Windows 7 SQLServer 2012 DBD::ODBC=1.609
Wierd issue with printf and DBD::Pg
HI If I use printf to round a numeric value before inserting into postgres table it is altered to 1 rather than the value when it is put into a table example CREATE TABLE public.chksize ( size numeric(10,2), #does not matter what field type path1 character varying COLLATE pg_catalog."default" ) this creates a value of 1 for every value my $ins=$dbh->prepare("INSERT into chksize (size,path1) VALUES (?,?) "); open my $list ,'chksizer.txt'; no strict 'refs'; my @list=(<$list>); foreach my $k (@list){ chomp $k; my ($size,$path)=split /,/,$k; my $size1=printf('%.1f',$size/(1024*1024)); $ins->bind_param(1,$size1); $ins->bind_param(2,$path); $ins->execute; } without printf this inserts proper value my $ins=$dbh->prepare("INSERT into chksize (size,path1) VALUES (?,?) "); open my $list ,'chksizer.txt'; no strict 'refs'; my @list=(<$list>); foreach my $k (@list){ chomp $k; my ($size,$path)=split /,/,$k; my $size1=$size/(1024*1024); $ins->bind_param(1,$size1); $ins->bind_param(2,$path); $ins->execute; } Any ideas what is happening here? thanks Mike
Translate between DBI and SQL
Has anyone done any work on converting SQL queries between RDBMS and perl? My particular interest is DBD::Pg but anything would be of use It would be very useful when I am testing complex SQL, it's very easy to miss a \ or quote between the two Thanks Mike
