我真的不懂啦~~很菜的~~能不能帮我解释一下这句
EXEC SQL CONNECT TO TEST@LOCALHOSR:54321 USER "SYSTEM"/"MANAGER";
谢谢了~~

我觉得我已经够菜的了，但是SQL基本语句还是读的懂的，帅哥你书都不看下这就不厚道了！

EXEC SQL BEGIN DECLARE SELTION  //主变量说明开始

char deptname[20];
char HSno[9];
char HSname[20];
char HSsex[2];
int HSage;
int NEWAGE;
EXEC SQL END DECLARE SECTION;//主变量说明结束

long SQLCODE;
EXEC SQL INCLUDE sqlca;//定义sql通信区

int main(void)
{int count=0;
char yn;
printf("Please choose the department name(CS/MA/IS):");
scanf("%s",&deptname);//C语言主程序开始

EXEC SQL CONNECT TO TEST@LOCALHOSR:54321 USER "SYSTEM"/"MANAGER";开始连接数据库
TEST@LOCALHOSR:54321数据库服务器
USER "SYSTEM"/"MANAGER"用户名
