SQLT_DAT操作使用char dat[7]来操作就可以, 具体每一个byte存放数据的含义请见:
http://blog.chinaunix.net/u/19782/showart.php?id=221290

操作是注意的地方
static ub1   in9[MAXITER][7];                 /* for DATE         */
要使用unsigned char

刚才自己使用时就只使用了char:
看一个简单的事例:

char a = 128;
printf("%d \n", a);

你看输出的结果是什么呢?当然不是128, 要不写出来就没意识了。是-128。
具体为什么?
可以自己比较一下:
int    a;
char    b;
unsigned char    c;

a = b = c = 128;

printf("int %d %02x \n", a, a);
printf("char %d %02x \n", b, b);
printf("unsigned char %d %02x \n", c, c);

输出的结果是:
int 128, 80
char -128, ffffff80
unsigned char 128, 80

该用无符号数的时候一定别忘了,害的自己一个错误找了N久。

如果使用不正确会出现类型DATE与NUMBER类型错误,ORA-00932

下面的代码来自Oracle, 可以用来比较与学习:

   NAME
     cdemord1.c - C DEMO program for DML with RETURNING clause - #1.

   DESCRIPTION
     This Demo program demonstrates the use of INSERT/UPDATE/DELETE
     statements with a RETURNING clause in it.
