说明：  这个是sql嵌入到c语言中的例子 原来：EXEC SQL CONNECT TO SKY.exp USER sa.sa //连接到数据库 更改：EXEC SQL CONNECT TO 8BC1D82B889C4FF.xixi USER sa. //连接到数据库 我装sql server时没改名，名字就叫8BC1D82B889C4FF xixi是一个数据库的名字 sa的密码为空。
(This is the sql embedded c language in the original example: EXEC SQL CONNECT TO SKY.exp USER sa.sa// connect to database changes: EXEC SQL CONNECT TO 8BC1D82B889C4FF.xixi USER sa.// Connect to the database when I installed sql server did not change its name, the name of a database called 8BC1D82B889C4FFxixi is the name of the sa password is blank.)
