Subject: Placeholders broken with mixed Integer/String usage

I've had some problems using DBD::mysql 2.1020 with Apache::Session which took me a while to track down. The problem is that if a placeholder is "primed" using an integer-type value, and then later used with a string, the placeholder expansion is broken. For more details see: For example if I run: #!/usr/bin/perl use DBD::mysql; my $dbh = DBI->connect("dbi:mysql:test", undef, undef); $dbh->do("DROP TABLE IF EXISTS test"); $dbh->do("CREATE TABLE test ( content varchar(255) )"); my $sql_str = "INSERT INTO test SET content = ?"; my $sth = $dbh->prepare($sql_str); $sth->execute(1); $sth->execute("foo"); I get DBD::mysql::st execute failed: Unknown column 'foo' in 'field list' at line 9. The workaround is to replace the first execute statement with $sth->execute("1"); Please let me know if you would like a patch for the code, or a documentation patch to add this to the "Known Problems" section of the POD. Thanks, TJ
