Question

我一直在使用pyodbc和免费的TDS向微软SQL-2012提交查询一段时间没有问题，但最近偶然发现了一个问题。当我提交更长的查询时，我收到一条错误消息，指出其中一个标识符太长而脚本崩溃了。 EXACT相同的查询在管理工作室中有效，甚至不会返回警告。我已将以下内容添加到我的代码中，但无济于事。

      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
    </form>
  </div>
</nav>

错误所指的代码片段在这里：

SET QUOTED_IDENTIFIER OFF
SET ANSI_NULLS ON

我得到的错误是：

(ZR_KOPF.ZRK_DDP_B IN ('190/TEMP.AA1H', '190/RAIN.AA1H', '190/WDR.AA1H', '190/WSP.AA1H', '190/SD1.AA1H', '190/HUMID.AA1H', '190/NO2.AA1H', '190/PM10.AA1H', '190/PM2.5.AA1H', '190/SO2.AA1H', '190/OZONE.AA1H', '190/CO.AA1H', '206/TEMP.AA1H', '206/RAIN.AA1H', '206/WDR.AA1H', '206/WSP.AA1H', '206/SD1.AA1H', '206/HUMID.AA1H', '206/NO2.AA1H', '206/PM10.AA1H', '206/PM2.5.AA1H', '206/SO2.AA1H', '206/OZONE.AA1H', '206/CO.AA1H')) AND ZR_KOPF.ZRK_BASEPRODUCTION = 1)
