Connecting to SQL Server on Linux: tsql works; isql cannot log in

问题

I am trying to set-up a connection to a SQL server instance using Linux. My FreeTDS setup seems to work, but my unixODBC set-up does not.

Here is what happens when I access the database with tsql:

tsql -S STCONNSQLDEV\\RscSwitchboard -U sa_RSCSWITCHBOARD -P password
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"

Here is what happens when I use isql:

isql RscSwitchboard sa_RSCSWITCHBOARD password -v
[S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source
[37000][unixODBC][FreeTDS][SQL Server]Login failed for user 'sa_RSCSWITCHBOARD'.
[ISQL]ERROR: Could not SQLConnect

I am using Ubuntu 14.04 x86_64. Does anyone have any suggestions?

回答1:

I would try the following:

== freetds.conf

[global]
    charset = UTF-8
    client charset = UTF-8
    timeout = 10
    connect timeout = 10

[server_a]
    host = 192.168.15.12
    port = 1433

== /etc/odbc.ini

[config_a]
Driver      = FreeTDS
Servername  = server_a
Database    = RscSwitchboard
Port        = 1433

$ isql -v config_a sa_RSCSWITCHBOARD password

And if that does not fix it then try the

tds version = 7.3
