linuxoraclec语言

A. 怎么在linux环境下通过c/c++语言连接oracle数据库

推荐你使用pc语言，用这个编写代码很容易对数据库oracle进行操作．各种操作都非常简单．
例如：
EXEC sql CONNECT :UserName IDENTIFIED BY :PassWord using :ServerName;
这样一个简单语句就可以实现连接数据库．
EXEC SQL CALL insert_data_sms(:spnumber,:usernumber,:content,:flag,:priority,:spnode,:sequenid_sp,:iresult);
EXEC SQL COMMIT;/*提交事务*/
可调用存储过程．
你可以找找这方便的书看看

B. linux下c++远程连接oracle数据库

你说的复合结构应该是结构体吧。若是举个例子给你看看

/*
 *  sample2.pc
 *
 *  This program connects to ORACLE, declares and opens a cursor,
 *  fetches the names, salaries, and commissions of all
 *  salespeople, displays the results, then closes the cursor.
 */
#include <stdio.h>
#include <sqlca.h>
#define UNAME_LEN      20
#define PWD_LEN        40
/*
 * Use the precompiler typedef’ing capability to create
 * null-terminated strings for the authentication host
 * variables. (This isn’t really necessary--plain char *’s
 * does work as well. This is just for illustration.)
 */
typedef char asciiz[PWD_LEN];
EXEC SQL TYPE asciiz IS STRING(PWD_LEN) REFERENCE;
asciiz     username;
asciiz     password;
struct emp_info
{
    asciiz     emp_name;
    float      salary;
    float      commission;
};
/* Declare function to handle unrecoverable errors. */
void sql_error();
main()
{
    struct emp_info *emp_rec_ptr;
/* Allocate memory for emp_info struct. */
    if ((emp_rec_ptr =
        (struct emp_info *) malloc(sizeof(struct emp_info))) == 0)
    {
        fprintf(stderr, "Memory allocation error.
");
        exit(1);
    }
/* Connect to ORACLE. */
    strcpy(username, "SCOTT");
    strcpy(password, "TIGER");
    EXEC SQL WHENEVER SQLERROR DO sql_error("ORACLE error--");
    EXEC SQL CONNECT :username IDENTIFIED BY :password;
    printf("
Connected to ORACLE as user: %s
", username);
/* Declare the cursor. All static SQL explicit cursors
 * contain SELECT commands. ’salespeople’ is a SQL identifier,
 * not a (C) host variable.
 */
    EXEC SQL DECLARE salespeople CURSOR FOR
    SELECT ENAME, SAL, COMM FROM EMP WHERE JOB LIKE ’SALES%’;
/* Open the cursor. */
    EXEC SQL OPEN salespeople;
/* Get ready to print results. */
    printf("

The company’s salespeople are--

");
    printf("Salesperson   Salary   Commission
");
    printf("-----------   ------   ----------
");
/* Loop, fetching all salesperson’s statistics.
  * Cause the program to break the loop when no more
 * data can be retrieved on the cursor.
  */
    EXEC SQL WHENEVER NOT FOUND DO break;
    for (;;)
    {
       EXEC SQL FETCH salespeople INTO :emp_rec_ptr;
       printf("%-11s%9.2f%13.2f
", emp_rec_ptr->emp_name,emp_rec_ptr->salary, emp_rec_ptr->commission);
    }
/* Close the cursor. */
    EXEC SQL CLOSE salespeople;
    printf("
Arrivederci.

");
    EXEC SQL COMMIT WORK RELEASE;
    exit(0);
}
void sql_error(msg) char *msg;
{
    char err_msg[512];
    int buf_len, msg_len;
    EXEC SQL WHENEVER SQLERROR CONTINUE;
    printf("
%s
", msg);
/* Call sqlglm() to get the complete text of the
  * error message.
*/
    buf_len = sizeof (err_msg);
    sqlglm(err_msg, &buf_len, &msg_len);
    printf("%.*s
", msg_len, err_msg);
    EXEC SQL ROLLBACK RELEASE;
    exit(1);
}

C. 关于linux方面找工作

你现在已经学习了linux的一些通用招式。我觉得你找一个系统管理员的工作应该问题不大。
如果要做开发工作，你就面临选择。你可以根据兴趣或者行业前景，要知道linux能做的事情很多，比如oracle的数据库,Java, Apache等都是最先在linux下实现的。C语言也是随着Unix诞生的。还有现在很火的移动终端android, 其内核还是linux。
所以，你要选择一个方向学习，比如你学习数据库，那可以用做金融，游戏，科研等；你学习内核，那你可以做驱动。
建议你接受zkx1217童鞋的建议。先投简历!!!!

D. LINUX C/C++用什么连接oracle数据库啊解决办法

在Windows的控制面板中，查找ODBC数据源，配置一个能够连接Oracle的数据源，并测试能够成功连接。然后在VS中连接这个数据源即可。

E. 我想在linux下用C语言连接远程oracle，可以不装客户端而用代码实现连接并操作吗如果可以，怎么连

必须使用orcale数据库提供的客户端开发库中的函数来和oracle数据库服务器来进行通讯。
