Windows和Linux系统下perl连接SQL Server数据库的方法

复制代码 代码如下:

use DBI;
 
# DBD::ODBC
 
my $dsn = ‘DBI:ODBC:Driver={SQL Server}‘;
my $host = ‘10.0.0.1,1433‘;
my $database = ‘my_database‘;
my $user = ‘sa‘;
my $auth = ‘s3cr3t‘;
 
# Connect via DBD::ODBC by specifying the DSN dynamically.
my $dbh = DBI->connect("$dsn;Server=$host;Database=$database",
 $user,
 $auth,
 { RaiseError => 1, AutoCommit => 1}
 ) || die "Database connection not made: $DBI::errstr";
 
#Prepare a SQL statement my $sql = "SELECT id, name, phone_number FROM employees ";
my $sth = $dbh->prepare( $sql );
 
#Execute the statement
$sth->execute();
 
my( $id, $name, $phone_number );
 
# Bind the results to the local variables
$sth->bind_columns( undef, \$id, \$name, \$phone_number );
 
#Retrieve values from the result set
while( $sth->fetch() ) {
 print "$id, $name, $phone_number\n";
}
 
#Close the connection
$sth->finish();
$dbh->disconnect();

复制代码 代码如下:

# Connect via DBD::ODBC using a System DSN
my $dbh = DBI->connect("dbi:ODBC:my_system_dsn",
 $user,
 $auth,
 {
 RaiseError => 1,
 AutoCommit => 1
 }
 ) || die "Database connection not made: $DBI::errstr";

复制代码 代码如下:

use DBI;
 
my $host = ‘10.0.0.1,1433‘;
my $database = ‘my_database‘;
my $user = ‘sa‘;
my $auth = ‘s3cr3t‘;
 
# DBD::ADO
$dsn = "Provider=sqloledb;Trusted Connection=yes;";
$dsn .= "Server=$host;Database=$database";
my $dbh = DBI->connect("dbi:ADO:$dsn",
 $user,
 $auth,
 { RaiseError => 1, AutoCommit => 1}
 ) || die "Database connection not made: $DBI::errstr";
 
#Prepare a SQL statement
my $sql = "SELECT id, name, phone_number FROM employees "; my $sth = $dbh->prepare( $sql );
 
#Execute the statement
$sth->execute();
 
my( $id, $name, $phone_number );
 
# Bind the results to the local variables
$sth->bind_columns( undef, \$id, \$name, \$phone_number );
 
#Retrieve values from the result set
while( $sth->fetch() ) {
 print "$id, $name, $phone_number\n";
}
 
#Close the connection
$sth->finish();
$dbh->disconnect();

复制代码 代码如下:

[SS_MY_DB]
host = 10.0.0.1 # or host name port = 1433
tds version = 7.0

复制代码 代码如下:

# load the DBI module
use DBI;
use DBD::Sybase;
 
my $database="my_database";
my $user="sa";
my $auth="s3cr3t";
 
BEGIN
{
 $ENV{SYBASE} = "/usr/local";
}
 
# Connect to the SQL Server Database
my $dbh = DBI->connect("dbi:Sybase:server=ss_my_db;database=$database",
 $user,
 $auth
 {RaiseError => 1, AutoCommit => 1}
 ) || die "Database connection not made: $DBI::errstr";
 
#Prepare a SQL statement
my $sql = "SELECT id, name, phone_number FROM employees";
my $sth = $dbh->prepare( $sql );
 
#Execute the statement
$sth->execute();
 
my( $id, $name, $phone_number );
 
# Bind the results to the local variables
$sth->bind_columns( undef, \$id, \$name, \$phone_number );
 
#Retrieve values from the result set
while( $sth->fetch() ) {  print "$name, $title, $phone\n";
}
 
#Close the connection
$sth->finish();
undef $sth; # This fixes a segfault bug with certain versions of DBD::Sybase
$dbh->disconnect();
