Question

我正在尝试使用FreeTDS和unixODBC从RHEL 5.5服务器连接到MSSQL服务器。

使用tsql我可以使用

连接到服务器

tsql -S mssqltest -U <username> -P <password>

它已成功连接

isql -v mssqltest 'username' 'password' -b -q

也没有任何问题连接

但在perl中，我收到如下错误消息

DBI connect('mssqltest',<username>,...) failed: [unixODBC][Driver Manager]Can't open lib '/usr/local/lib/libtdsodbc.so' : file not found (SQL-01000) at test.pl line 14
Can't connect to DBI:ODBC:mssqltest: [unixODBC][Driver Manager]Can't open lib '/usr/local/lib/libtdsodbc.so' : file not found (SQL-01000) at test.pl line 14.

我尝试使用FreeTDS作为ODBC驱动程序也会出现类似错误，我尝试使用servername而不是server_ip，但错误仍在继续

DBI connect('Driver=FreeTDS;Server=<server_ip>',<username>,...) failed: [unixODBC][Driver Manager]Can't open lib '/usr/local/lib/libtdsodbc.so' : file not found (SQL-01000) at test.pl line 14
Can't connect to DBI:ODBC:Driver=FreeTDS;Server=<server_ip>: [unixODBC][Driver Manager]Can't open lib '/usr/local/lib/libtdsodbc.so' : file not found (SQL-01000) at test.pl line 14.

我的perl代码

#!/usr/bin/perl -w
use strict;

use DBI;

# Replace datasource_name with the name of your data source.
# Replace database_username and database_password
# with the SQL Server database username and password.
my $data_source = q/DBI:ODBC:mssqltest/;
my $user = q/<username>/;
my $password = q/<password>/;

# Connect to the data source and get a handle for that connection.
my $dbh = DBI->connect($data_source, $user, $password)
    or die "Can't connect to $data_source: $DBI::errstr";

# This query generates a result set with one record in it.
my $sql = "SELECT TOP 3 * FROM tablename";

# Prepare the statement.
my $sth = $dbh->prepare($sql)
    or die "Can't prepare statement: $DBI::errstr";

# Execute the statement.
$sth->execute();

# Print the column name.
print "$sth->{NAME}->[0]\n";

# Fetch and display the result set value.
while ( my @row = $sth->fetchrow_array ) {
   print "@row\n";
}

# Disconnect the database from the database handle.
$dbh->disconnect;

请帮忙。

isql和tsql正在连接到sql server，但是当与perl ODBC连接时，它会失败
