  • how to query sqlite for certain rows, i.e. dividing it into pages (perl DBI)

    - by user1380641
    sorry for my noob question, I'm currently writing a perl web application with sqlite database behind it. I would like to be able to show in my app query results which might get thousands of rows - these should be split in pages - routing should be like /webapp/N - where N is the page number. what is the correct way to query the sqlite db using DBI, in order to fetch only the relavent rows. for instance, if I show 25 rows per page so I want to query the db for 1-25 rows in the first page, 26-50 in the second page etc.... Thanks in advanced!

  • DB2 with mod_perl not working, works fine in CGI

    - by Matthew
    Hi, I'm having issues with getting DBI's IBM DB2 driver to work with mod_perl. My test script is: #!/usr/bin/perl use CGI; use Data::Dumper; use DBI; $q = CGI->new; print $q->header; print $q->start_html(); $dsn = "DBI:DB2:SAMPLE"; $username = "username"; $password = "password"; $dbc = DBI->connect($dsn, $username, $password); $sth = $dbc->prepare("SELECT * FROM SOME_TABLE WHERE FIELD='SOMETHING'"); $sth->execute(); $row = $sth->fetchrow_hashref(); print "<pre>".$q->escapeHTML(Dumper($row))."</pre>"; print $q->end_html; This script works as CGI but not under mod_perl. I get this error in apache's error log: DBD::DB2::dr connect warning: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /usr/lib/perl5/site_perl/5.8.8/Apache/DBI.pm line 190. DBI connect('SAMPLE','username',...) failed: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /data/www/perl/test.pl line 15 First of all, why is it using ODBC? The native DB2 driver is installed (hence it works as CGI). Running Apache 2.2.3, mod_perl 2.0.4 under RHEL5. This guy had the same problem as me: http://www.mail-archive.com/[email protected]/msg22909.html But I have no idea how he fixed it. What does mod_php4 have to do with mod_perl? Any help would be greatly appreciated, I'm having no luck with google.

  • How do I insert null fields with Perl's DBD::Pg?

    - by User1
    I have a Perl script inserting data into Postgres according to a pipe delimited text file. Sometimes, a field is null (as expected). However, Perl makes this field into an empty string and the Postgres insert statement fails. Here's a snippet of code: use DBI; #Connect to the database. $dbh=DBI-connect('dbi:Pg:dbname=mydb','mydb','mydb',{AutoCommit=1,RaiseError=1,PrintError=1}); #Prepare an insert. $sth=$dbh-prepare("INSERT INTO mytable (field0,field1) SELECT ?,?"); while (<){ #Remove the whitespace chomp; #Parse the fields. @field=split(/\|/,$_); print "$_\n"; #Do the insert. $sth-execute($field[0],$field[1]); } And if the input is: a|1 b| c|3 EDIT: Use this input instead. a|1|x b||x c|3|x It will fail at b|. DBD::Pg::st execute failed: ERROR: invalid input syntax for integer: "" I just want it to insert a null on field1 instead. Any ideas? EDIT: I simplified the input at the last minute. The old input actually made it work for some reason. So now I changed the input to something that will make the program fail. Also note that field1 is a nullable integer datatype.

  • Random Connections to MySQL refused (Error 111)

    - by joatis
    A Perl/CGI webapp that has been running fine for almost a year has started to randomly been unable to connect to a remotely hosted MySQL. The Error thrown is : Can't connect to MySQL server on 'xx.x.xxx.xx' (111) Reloading the page often solves the problem The client is using Perl, DBI and SSL to connect to MySQL using the same configuration file each time. MySQL 5.0 Server Running RH EL5 Quad-Core AMD Opteron(tm) Processor 2374 HE, 8 cores Real Memory: 15.73 GB total, 11.81 GB used allows networking in my.cnf max-connections are not being met load is low. The servers firewall is open to the client's subnet. The mysql user has permissions from the client's subnet. I have my host looking into the problem but so far we're all stumped as to way the occasional connection is (increasingly getting refused) Any advice what to check that would cause the random refusal of connections?

  • DBD::CSV: How can I generate different behavior with the two f_ext-options ".csv" and ".csv/r"?

    - by sid_com
    This is from the DBD::File-documentation: f_ext This attribute is used for setting the file extension where (CSV) files are opened. There are several possibilities. DBI:CSV:f_dir=data;f_ext=.csv In this case, DBD::File will open only table.csv if both table.csv and table exist in the datadir. The table will still be named table. If your datadir has files with extensions, and you do not pass this attribute, your table is named table.csv, which is probably not what you wanted. The extension is always case-insensitive. The table names are not. DBI:CSV:f_dir=data;f_ext=.csv/r In this case the extension is required, and all filenames that do not match are ignored. It was not possible for me to generate different behavior with the two options ".csv/r" and ".csv". Could someone show me an example, where I can see the difference between ".csv/r" and ".csv"?

  • Perl TDS character sets

    - by skiphoppy
    I'm using the FreeTDS driver with DBD::Sybase, connecting to an MS SQL Server. When I query certain values of certain records, I get this error: DBD::Sybase::st fetchrow_arrayref failed: OpenClient message: LAYER = (0) ORIGIN = (0) SEVERITY = (9) NUMBER = (99) Server , database Message String: WARNING! Some character(s) could not be converted into client's character set. Unconverted bytes were changed to question marks ('?'). This seems to happen for records that contain special Windows character-set characters, such as curly quotes, copied and pasted from people's Outlook and Word messages. Unfortunately, I do not have any control of this database; sanitizing the input on the way in is obviously the way to go, but is not available to me. What FreeTDS settings do I need to change to be able to successfully query these records? Additional information: The query works fine from tsql. I only get this error through Perl's DBD::Sybase interface. (Should I test through something else? I don't have the expertise yet to install PHP or Python. I've got jTDS and can use it, but I think that's a completely different implementation, not an interface to FreeTDS.) Adding client charset = UTF-8 to my freetds.conf file results in "Out of memory!" printed to STDERR.

  • Invalid UTF-8 for Postgres, Perl thinks they're ok

    - by gorilla
    I'm running perl 5.10.0 and Postgres 8.4.3, and strings into a database, which is behind a DBIx::Class. These strings should be in UTF-8, and therefore my database is running in UTF-8. Unfortunatly some of these strings are bad, containing malformed UTF-8, so when I run it I'm getting an exception DBI Exception: DBD::Pg::st execute failed: ERROR: invalid byte sequence for encoding "UTF8": 0xb5 I thought that I could simply ignore the invalid ones, and worry about the malformed UTF-8 later, so using this code, it should flag & ignore the bad titles. if(not utf8::valid($title)){ $title="Invalid UTF-8"; } $data->title($title); $data->update(); However perl seems to think that the strings are valid, but it still throws the exceptions. How can I get perl to detect the bad UTF-8?

    I am in search of who specifically to contact at Sybase regarding Advantage Database Server's DBI driver, specifically DBD::Advantage. The only reference I can find is to one 'lancesc' in the README, but there are no references to a contact email, CPAN author etc. Inadvertantly I happened upon one StackOverflow user lancesc here. Would anyone happen to know who to contact regarding this? I do wish this was on CPAN. I've found a small bug regarding column quoting in the sql parser that they'd likely prefer to be made aware of. There are also several questions I have for them regarding failing functionality.

  • In mysql, is "explain ..." always safe?

    - by tye
    If I allow a group of users to submit "explain $whatever" to mysql (via Perl's DBI using DBD::mysql), is there anything that a user could put into $whatever that would make any database changes, leak non-trivial information, or even cause significant database load? If so, how? I know that via "explain $whatever" one can figure out what tables / columns exist (you have to guess names, though) and roughly how many records are in a table or how many records have a particular value for an indexed field. I don't expect one to be able to get any information about the contents of unindexed fields. DBD::mysql should not allow multiple statements so I don't expect it to be possible to run any query (just explain one query). Even subqueries should not be executed, just explained. But I'm not a mysql expert and there are surely features of mysql that I'm not even aware of. In trying to come up with a query plan, might the optimizer actual execute an expression in order to come up with the value that an indexed field is going to be compared against? explain select * from atable where class = somefunction(...) where atable.class is indexed and not unique and class='unused' would find no records but class='common' would find a million records. Might 'explain' evaluate somefunction(...)? And then could somefunction(...) be written such that it modifies data?

  • How can I make hundreds of simultaneously running processes communicate with a database through one

    - by Olfan
    Long speech short: How can I make hundreds of simultaneously running processes communicate with a database through one or few permanent sessions? The whole story: I once built a number crunching engine that handles vast amounts of large data files by forking off one child after another giving each a small number of files to work on. File locking, progress monitoring and result propagation happen in an Oracle database which all (sub-)processes access at various times using an application-specific module which encapsulates DBI. This worked well at first, but now with higher volumes of input data, the number of database sessions (one per child, and they can be very short-lived) constantly being opened and closed is becoming an issue. I now want to centralise database access so that there are only one or few fixed database sessions which handle all database access for all the (sub-)processes. The presence of the database abstraction module should make the changes easy because the function calls in the worker instances can stay the same. My problem is that I cannot think of a suitable way to enhance said module in order to establish communication between all the processes and the database connector(s). I thought of message queueing, but couldn't come up with a way of connecting a large herd of requestors with one or few database connectors in a way so that bidirectional communication is possible (for collecting the query result). An asynchronous approach could help here in that all requests are written to the same queue and the database connector servicing the request will "call back" to submit the result. But my mind fails me in generating an image clear enough so that I can paint into code. Threading instead of forking might have given me an easier start, but this would now require massive changes to the code base that I'm not prepared to do to a live system. The more I think of it, the more the base idea looks like a pre-forked web server to me only that it doesn't serve web pages but database queries. Any ideas on what to dig into, and where? Sample (pseudo) code to inspire me, links to possibly related articles, ready solutions on CPAN maybe?

  • FreeTDS runs out of memory from DBD::Sybase

    - by skiphoppy
    When I add client charset = UTF-8 to my freetds.conf file, my DBD::Sybase program emits: Out of memory! and terminates. This happens when I call execute() on an SQL query statement that returns any ntext fields. I can return numeric data, datetimes, and nvarchars just fine, but whenever one of the output fields is ntext, I get this error. All these queries work perfectly fine without the UTF-8 setting, but I do need to handle some characters that throw warnings under the default character set. (See related question.) The error message is not formatted the same way other DBD::Sybase error messages seem to be formatted. I do get a message that a rollback() is being issued, though. (My false AutoCommit flag is being honored.) I think I read somewhere that FreeTDS uses the iconv program to convert between character sets; is it possible that this message is being emitted from iconv? If I execute the same query with the same freetds.conf settings in tsql (FreeTDS's command-line SQL shell), I don't get the error. I'm connecting to SQL Server. What do I need to do to get these queries to return successfully?

  • How can I correctly quote query parameters using DBI?

    - by imerez
    I am dumping the a number of things including the following into a db INSERT statement \"$rec->{reqHdrs}\" However when for example my value for reqHdrs contains quotes it causes the statement to end and thus cause invalid sql. e.g. bla;bla="http://www.yahoo.com/xhtml",bla bla How do I escape the double quotes inside this statement ?

  • How to install DBD::mysql on OS X Server 10.6?

    - by Zoran Simic
    Trying to install DBD::mysql on OS X Server 10.6 (mac mini server). But I'm missing the mysql headers apparently. Since mysql is already part of OS X Server 10.6, I would like to NOT install anything else (no fink or darwin ports installs), just whatever's needed to get DBD::mysql installed and working. Do you know how I could do that? Do I have to install the headers somewhere? And if so, where? (again: I don't want to install another version of mysql on the box, want to use the version it came with). Is there a way to install DBD::mysql without compiling any C files? This is the error I get (the actual error is much longer, but these are the most meaningful bits, this is the first error reported). Checking if your kit is complete... Looks good Unrecognized argument in LIBS ignored: '-pipe' Note (probably harmless): No library found for -lmysqlclient Multiple copies of Driver.xst found in: /Library/Perl/5.10.0/darwin-thread-multi-2level/auto/DBI/ /System/Library/Perl/Extras/5.10.0/darwin-thread-multi-2level/auto/DBI/ at Makefile.PL line 907 Using DBI 1.611 (for perl 5.010000 on darwin-thread-multi-2level) installed in /Library/Perl/5.10.0/darwin-thread-multi-2level/auto/DBI/ Writing Makefile for DBD::mysql cp lib/DBD/mysql.pm blib/lib/DBD/mysql.pm cp lib/DBD/mysql/GetInfo.pm blib/lib/DBD/mysql/GetInfo.pm cp lib/DBD/mysql/INSTALL.pod blib/lib/DBD/mysql/INSTALL.pod cp lib/Bundle/DBD/mysql.pm blib/lib/Bundle/DBD/mysql.pm gcc-4.2 -c -I/Library/Perl/5.10.0/darwin-thread-multi-2level/auto/DBI -I/usr/include -fno-omit-frame-pointer -pipe -D_P1003_1B_VISIBLE -DSIGNAL_WITH_VIO_CLOSE -DSIGNALS_DONT_BREAK_READ -DIGNORE_SIGHUP_SIGQUIT -DDBD_MYSQL_INSERT_ID_IS_GOOD -g -arch x86_64 -arch i386 -arch ppc -g -pipe -fno-common -DPERL_DARWIN -fno-strict-aliasing -I/usr/local/include -Os -DVERSION=\"4.014\" -DXS_VERSION=\"4.014\" "-I/System/Library/Perl/5.10.0/darwin-thread-multi-2level/CORE" dbdimp.c In file included from dbdimp.c:20: dbdimp.h:22:49: error: mysql.h: No such file or directory dbdimp.h:23:45: error: mysqld_error.h: No such file or directory dbdimp.h:25:49: error: errmsg.h: No such file or directory
