        isql  mydsn sa Tiansign2012 -w < out.sql
done

配置：

对于使用isql需要配置，应用用sqlcmd会报错，找不到，

isql需要配置一下文件

/usr/local/etc/odbc.ini

[mydsn]
Driver= SQL ServerNativeClient11.0
Database= datbase
Server= xxx.xxx.xxx.xxx,port

/usr/local/etc/odbcinst.ini

[SQL ServerNativeClient11.0]
Description=Microsoft SQL Server ODBC Driver V1.0forLinux
Driver=/opt/microsoft/sqlncli/lib64/libsqlncli-11.0.so.1790.0
