javascript - 如何在 JavaScript 中正确引用 Oracle SQL 字符串

Question

在我的 node.js 应用程序中，我需要运行 Oracle 查询，如下所示:

var last_reported_date = '2016-05-09 18:16:59';

 var query = 'SELECT "HpdHelpdesk".INCIDENTNUMBER,' +
        '"HpdHelpdesk".SUBMITTER,' +
        '"HpdHelpdesk".REPORTEDDATE,' +
        '"HpdHelpdesk".LASTRESOLVEDDATE,' +
        '"HpdHelpdesk".OWNERGROUP,' +
        '"HpdHelpdesk".COMPANY,' +
        '"HpdHelpdesk".CATEGORIZATIONTIER1,' +
        '"HpdHelpdesk".CATEGORIZATIONTIER2,' +
        '"HpdHelpdesk".CATEGORIZATIONTIER3,' +
        '"HpdHelpdesk".RESOLUTIONCATEGORY,' +
        '"HpdHelpdesk".RESOLUTIONCATEGORYTIER2,' +
        '"HpdHelpdesk".RESOLUTIONCATEGORYTIER3,' +
        '"HpdHelpdesk".REPORTEDSOURCE,' +
        '"HpdHelpdesk".DESCRIPTION,' +
        '"HpdHelpdesk".ID' +
' FROM "HpdHelpdesk" ' +
'WHERE "HpdHelpdesk".REPORTEDDATE > TO_DATE(' + last_reported_date + ',' + 'YYYY-MM-DD HH24:MI:SS)';

当我运行此命令时，出现以下 Oracle 错误:错误:ORA-00907:缺少右括号

格式化此类查询以避免此错误的正确方法是什么？

Answer 1

您仅从单个表中进行选择，因此无需为每个列名称添加表名称前缀。此外，您还缺少查询末尾的 TO_DATE 函数的上次报告日期和格式掩码周围的引号。

var last_reported_date = '2016-05-09 18:16:59';

var query = 'SELECT INCIDENTNUMBER,' +
        'SUBMITTER,' +
        'REPORTEDDATE,' +
        'LASTRESOLVEDDATE,' +
        'OWNERGROUP,' +
        'COMPANY,' +
        'CATEGORIZATIONTIER1,' +
        'CATEGORIZATIONTIER2,' +
        'CATEGORIZATIONTIER3,' +
        'RESOLUTIONCATEGORY,' +
        'RESOLUTIONCATEGORYTIER2,' +
        'RESOLUTIONCATEGORYTIER3,' +
        'REPORTEDSOURCE,' +
        'DESCRIPTION,' +
        'ID' +
' FROM "HpdHelpdesk" ' +
'WHERE REPORTEDDATE > TO_DATE( \'' + last_reported_date + '\', \'YYYY-MM-DD HH24:MI:SS\')';
