自2011年以来一直处理此问题。通常能够解决此问题。现在出现了这样一种情况:我真的需要能够处理错误,而且我在想,人们多年以来就知道这个问题,看起来像是修复列表上的高级事物,但最新的DBI升级问题仍未解决。有没有人找到解决办法,或知道如何破解库,并获取DBI :: errstr携带值时出现错误?Win 64草莓Perl DBI没有错误报告错误仍然没有解决?

这里是我的代码(是我知道的问题瓦特/空的root密码):现在

use strict; 
use DBI; 
use DBD::mysql; 
use Data::Dumper; 

my $platform = "mysql"; 
my $database = "test"; 
my $host = "localhost"; 
my $port = "3306"; 
my $user = "root"; 
my $pw = ""; 
my $dsn; 

$dsn = "dbi:mysql:$database:$host:$port"; 

my $DBI_connect = DBI->connect($dsn, $user, $pw, {RaiseError => 1,PrintError=>1}) or die "$DBI::errstr\n"; 

my $sql_str = 'INSERT INTO test_tablexx (\'xxx) VALUES (blah)'; 

my $DBI_query_handle = $DBI_connect->prepare($sql_str) or die "Can't prepare SQL statement: $DBI::errstr\n"; 

my $return = $DBI_query_handle->execute() or warn "$DBI::errstr\n"; 

print "sys arry".Dumper [email protected]"\n"; 
print "err: ".$DBI_query_handle->err."\n"; 
print "errstr: ".$DBI_query_handle->errstr."\n"; 
print "state: ".$DBI_query_handle->state."\n"; 

print "err: ".$DBI_connect->err."\n"; 
print "errstr: ".$DBI_connect->errstr."\n"; 
print "state: ".$DBI_connect->state."\n"; 
print Dumper $DBI_query_handle; 

print "\n\n-------------------------------------------------------------------\n\n"; 

my $hash = DBI->installed_versions; 
print Dumper $hash; 

,该表是无效的,列有在它和中间报价值是一个未加引号的字符串。应该像圣诞树一样点亮错误处理。

如果我将执行语句更改为“$ DBI :: errstr \ n”,它会出错:它会死亡,但根本没有消息。

然而,这里是结果:

sys arry$VAR1 = ' 
'; 
err: 
errstr: 
state: 
err: 
errstr: 
state: 
$VAR1 = bless({}, 'DBI::st'); 

------------------------------------------------------------------- 

$VAR1 = { 
    'DBD::SQLite' => '1.37', 
    'DBD::ExampleP' => '12.014311', 
    'DBD::Sponge' => '12.010003', 
    'DBD::Pg' => bless({ 
          'original' => '2.19.3', 
          'qv' => 1, 
          'version' => [ 
              2, 
              19, 
              3 
             ] 
         }, 'version'), 
    'DBD::Gofer' => '0.015327', 
    'DBD::DBM' => '0.08', 
    'DBD::mysql' => '4.022', 
    'DBD::ADO' => '2.99', 
    'DBD::ODBC' => '1.41', 
    'DBI' => '1.631', 
    'DBD::File' => '0.42' 
    }; 

的最后一位是版本信息转储,所以你们可以看到我最新的与我的DBI安装。

现在,当我改变数据库的东西不存在,例如:我的$ database =“的testXXX”,它确实火了一个错误:

DBI connect('testxx:localhost:3306','root',...) failed: Unknown database 'testxx' at ../sql_tester.pl line 17. 

的信息的最后一位为你当我倾倒$ DBI :: lasth,我可以看到错误的方法是联合国民主基金:

print Dumper $DBI::lasth; 

$VAR1 = bless({ 
      'FetchHashKeyName' => 'NAME', 
      'TraceLevel' => 0, 
      'ImplementorClass' => 'DBD::mysql::db', 
      'dbi_imp_data' => undef, 
      'State' => \undef, 
      'Username' => 'root', 
      'Errstr' => \undef, 
      'ChildHandles' => [ 
           bless({}, 'DBI::st') 
           ], 
      'Driver' => bless({ 
           'Attribution' => 'DBD::mysql by Patrick Galbraith', 
           'FetchHashKeyName' => 'NAME', 
           'TraceLevel' => 0, 
           'ImplementorClass' => 'DBD::mysql::dr', 
           'State' => \undef, 
           'Version' => '4.022', 
           'Errstr' => \undef, 
           'ChildHandles' => [ 
                bless({}, 'DBI::db') 
                ], 
           'Name' => 'mysql', 
           'Err' => \undef 
           }, 'DBI::dr'), 
      'Statement' => 'INSERT INTO test_tablexx (\'xxx) VALUES (blah)', 
      'Name' => 'test:localhost:3306', 
      'dbi_connect_closure' => sub { "DUMMY" }, 
      'Err' => \undef 
      }, 'DBI::db'); 

所以请请的这么好的人,我该怎么办时,编程的最重要的原则之一 - 错误处理 - 在我的程序的核心模块中不起作用?!

模块的作者在报告错误时说了些什么? – ikegami
