如何在JavaScript中正确引用Oracle SQL字符串

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，我得到以下Oracle错误：

错误：ORA-00907:缺少右括号

设置此类查询的格式以避免此错误的正确方法是什么？

您仅从单个表中进行选择，因此不需要在每个列名前面加上表名。此外，在查询结束时，

TO_date

函数的上次报告日期和格式掩码周围缺少引号

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\')';

添加到MTO的答案中，您需要为每个换行符添加空格，这样您就不会得到一个没有空格的长字符串：

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\')';
