OCCI SetDataBuffer为double值

Question

在这个例子中，我们有通过OCCI函数在Oracle数据库中插入int和char值的代码。    我试图通过setDataBuffer插入双值，但它插入一些垃圾值。在这种情况下，我认为我传递的是错误的大小或长度。有人可以通过更新以下示例来帮助插入双值。

    Statement *stmt = conn->createStatement(
    "insert into departments (department_id, department_name) values(:1, :2)"); 
    char dnames[][100] = {"Community Outreach", "University Recruiting"}; 
    ub2 dnameLen[2]; 

   for (int i = 0; i < 2; i++) 
    dnameLen[i] = strlen(dnames[i] + 1); 

    int ids[2] = {7369, 7654}; 
    ub2 idLen[2] = {sizeof(ids[0]), sizeof(ids[1])}; 
    stmt->setDataBuffer(1, ids, OCCIINT, sizeof(ids[0]), idLen); 
    stmt->setDataBuffer(2, dnames, OCCI_SQLT_STR, sizeof(dnames[0]), dnameLen);
