perlquestion kudra I am trying to insert a large object in a PostgreSQL database, but am having difficulties finding a graceful way to do this. Note that the included code has been simplified to avoid distractions--I am well aware that I should be addressing possible errors. <p> System information:<br> <ul><li>perl, version 5.005_03</li> <li>Linux 2.2.14 i686</li> <li>Postgres: 6.5.3</li> <li>DBI: 1.1.3</li> <li>DBD Pg: 0.93</li></ul> <p> I have created a table with one field, <strong>data</strong>, which is of type OID. Next I attempt to insert by more or less copying the code on page 153 of 'Programming the Perl DBI': <code> my $sth = $dbh->prepare("insert into foo(data) values (?);"); $sth->bind_param(1, $value, SQL_LONGVARBINARY); $sth->execute(); </code> I receive a warning that binding the value isn't permitted: <code> SQL type 1075548612 for 'rc' is not fully supported, bound as VARCHAR instead at ./1.0 line 122. </code> Whereupon it fails with a pg_atoi error. <p> I can insert by writing $value to a file and using the (presumably Postgres-specific) function lo_import: <code> $dbh->prepare("insert into foo(data) values (lo_import('/tmp/lame'));") </code> I'm not pleased with this solution because it requires the creation of a temporary file and it seems to undermine the use of DBI to use a database-specific insert. <p> I imagine some of the problem has to do with the unusual way Postgres deals with large objects. I expected that the Pg DBD would compensate for that, perhaps using lo_import, but accepting the format shown earlier. <p> The fact that I can't seem to find any documentation mentioning this problem (which I imagine must have occurred before) makes me feel as if I've completely failed to grasp something simple (or that Pg's documentation-dearth is contagious, affecting anything that touches Postgres). Is there a better way to insert a large object in Postgres using DBI? Thanks in advance.
