ubuntu下qt连接sqlserver2008

最近在弄qt连接sqlserver2008,总是出现如下错误提示.

[unixODBC][Driver Manager]Data source name not found, and no default driver specified QODBC3: Unable to connect

对于上述错误,我在网上找遍了,也没有找到结果.但是最后被我偶然试出来了.特此记录一下,给日后提醒.

相关的测试库,odbc,freetds,qt等等库都是要装的

首先是下面配置文件,要确保正确.

# vim /etc/freetds/freetds.conf

[factorytest]

host = 192.168.1.7

port = 1433

tds version = 8.0

# vim /etc/odbc.ini

[factorytest]

Driver = SQLServer

Description = SQLServer

Server = 192.168.1.7

Database = factorytest

Port = 1433

# vim /etc/odbcinst.ini

[ODBC]

Trace = Yes

TraceFile = /tmp/sql.log

ForceTrace = Yes

Pooling = No

[SQLServer]

Description = SQLServer

Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so

Setup = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so

UsageCount = 1

CPTimeout = 5

CPReuse = 5

FileUsage = 1
