linuxoraclec語言

A. 怎麼在linux環境下通過c/c++語言連接oracle資料庫

推薦你使用pc語言，用這個編寫代碼很容易對資料庫oracle進行操作．各種操作都非常簡單．
例如：
EXEC sql CONNECT :UserName IDENTIFIED BY :PassWord using :ServerName;
這樣一個簡單語句就可以實現連接資料庫．
EXEC SQL CALL insert_data_sms(:spnumber,:usernumber,:content,:flag,:priority,:spnode,:sequenid_sp,:iresult);
EXEC SQL COMMIT;/*提交事務*/
可調用存儲過程．
你可以找找這方便的書看看

B. linux下c++遠程連接oracle資料庫

你說的復合結構應該是結構體吧。若是舉個例子給你看看

/*
 *  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. 關於linux方面找工作

你現在已經學習了linux的一些通用招式。我覺得你找一個系統管理員的工作應該問題不大。
如果要做開發工作，你就面臨選擇。你可以根據興趣或者行業前景，要知道linux能做的事情很多，比如oracle的資料庫,Java, Apache等都是最先在linux下實現的。C語言也是隨著Unix誕生的。還有現在很火的移動終端android, 其內核還是linux。
所以，你要選擇一個方向學習，比如你學習資料庫，那可以用做金融，游戲，科研等；你學習內核，那你可以做驅動。
建議你接受zkx1217童鞋的建議。先投簡歷!!!!

D. LINUX C/C++用什麼連接oracle資料庫啊解決辦法

在Windows的控制面板中，查找ODBC數據源，配置一個能夠連接Oracle的數據源，並測試能夠成功連接。然後在VS中連接這個數據源即可。

E. 我想在linux下用C語言連接遠程oracle，可以不裝客戶端而用代碼實現連接並操作嗎如果可以，怎麼連

必須使用orcale資料庫提供的客戶端開發庫中的函數來和oracle資料庫伺服器來進行通訊。
