Manvi · 技术社区 · 7 年前

我正在尝试使用MS SQL driver 13从Linux虚拟环境连接到MS SQL Server实例。

[<user> ~]$ which odbcinst
/usr/bin/odbcinst
[<user> ~]$ odbcinst -j
unixODBC 2.3.1
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /home/<user>/.odbc.ini

SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8
[<user> ~]$ cat /etc/odbc.ini
[DNSname-1]
Driver = ODBC Driver 13 for SQL Server
SERVER=server-1
DATABASE=DB1

[DNSname-2]
Driver = ODBC Driver 13 for SQL Server
SERVER=server-2\instance-1
Database=DB2
[<user> ~]$ isql DNSname-1 userid1 passwd1

isql能够连接到ms sql server

[<root> ~]$ isql -v DNSname-2 userid2 passwd2

但当我尝试连接到sql db实例时,isql给出了一个错误,即“登录超时已过期”
