我有以下C代码,它使用存储过程将2个字符串插入数据库:

char query[1024];

memset(query, 0, sizeof(query));
sprintf(query, "BEGIN bns_saa_message_insert (:1, :2); END;");


/* prepare statement */
if( checkerr(errhp, OCIStmtPrepare(stmthp, errhp, (text *) query,
        (ub4) strlen((char *) query),
        (ub4) OCI_NTV_SYNTAX, (ub4) OCI_DEFAULT)) == OCI_ERROR)
    return -1;


/* bind input params */
if( checkerr(errhp, OCIBindByPos(stmthp, &bndhp, errhp, (ub4) 1, (dvoid *) hostNumber,
        (sword) sizeof(hostNumber) - 1, SQLT_CHR, (dvoid *) 0,
        (ub2 *) 0, (ub2) 0, (ub4) 0, (ub4 *) 0, OCI_DEFAULT)) == OCI_ERROR)
    return -1;

if( checkerr(errhp, OCIBindByPos(stmthp, &bndhp, errhp, (ub4) 1, (dvoid *) saaMessage,
        (sword) sizeof(saaMessage) - 1, SQLT_CHR, (dvoid *) 0,
        (ub2 *) 0, (ub2) 0, (ub4) 0, (ub4 *) 0, OCI_DEFAULT)) == OCI_ERROR)
    return -1;
//end of param binding

printf(“query:%s”,query);//这表明在我执行上述绑定时,param1和param2没有被替换
/* execute the statement */
status = OCIStmtExecute(svchp, stmthp, errhp, (ub4) 1, (ub4) 0,
        (CONST OCISnapshot *) NULL, (OCISnapshot *) NULL, OCI_DEFAULT);

我得到的错误是:
ORA-01008:并非所有变量都绑定
上面代码中概述的printf输出:
查询:开始bns_saa_消息插入(:1,:2);结束;
问题
如何修复此错误?

我在这里看到了用C或Java回答的类似问题,但不是C
"ORA-01008: not all variables bound" error
ORA-01008: not all variables bound. They are bound

最佳答案

看起来是个小错误。对OCIBindByPos的第二次调用应该对第四个参数使用2而不是1

if( checkerr(errhp, OCIBindByPos(stmthp, &bndhp, errhp, (ub4) 2, (dvoid *) saaMessage,
