我正使用 c++ 前端的 sqlite db 进行工作。 当我试图在查询中绑定变量时, 它会给出以下错误 。

这里是代码

           for(vector<vector<string> >::iterator it = result.begin(); it < result.end(); ++it)
            {
                vector<string> row = *it;                     
                **sqlite3_bind_text(statement,2,[row.at(1) string],-1, SQLITE_TRANSIENT);**                     
                int result = sqlite3_step(statement);
            }

粗体线表示问题在于 " 无法将`数据库::InitialSync ():: '改为`Cont char ',作为`3'的论据改为`int sqlite3_bind_text(sqlite3_stmt*, int, const char*, int, valent ()(避免 ))'" 。

有人能帮我吗?

最佳回答

您的语法错误, 请使用

sqlite3_bind_text(statement,2, row[1].c_str(), -1, SQLITE_TRANSIENT);

如果您需要从行数组中键入第一个值(而不是零),则需要从行数组中键入第一个值(而不是零)。

如果我误解了您, 请澄清您想要做的事情, 不仅仅是这个编译错误。 我的意思是您想要绑定的参数 。
