Question

我正在开发SAPUI5应用程序。我需要从db中检索数据，而我使用的是.xsjs，这是我的ajax调用：

jQuery.ajax({
            url : "/SimpleProject/services/querytest.xsjs",
            method: "GET",
            success: function(response) {
                console.log(JSON.parse(response));
            },
            error: function(e) {
                sap.ui.commons.MessageBox.alert("ERROR");
            }
        });

这是我的.xsjs文件，我尝试查询SAP HANA数据库。

    try {
    $.response.contentType = "application/json"; 

    var conn = $.db.getConnection();

    var statement = conn.prepareStatement('SELECT * FROM "_SYS_BIC"."TABLETEST"');
    var rs = statement.executeQuery();

    conn.commit();

    if (rs != undefined)
        $.response.setBody(JSON.stringify(rs));
    else $.response.setBody(JSON.stringify("empty record set"));

    $.response.status = $.net.http.OK;
} catch(e) {
    $.response.status = $.net.http.INTERNAL_SERVER_ERROR;
    $.response.setBody(JSON.stringify(e));
} finally {
    statement.close();
    conn.close();
}

如果我从SQL控制台执行查询，它可以正常工作，但是从xsjs返回的结果总是空的。

我修复了它，我不能将“rs”对象作为输出发送，但我必须构建另一个对象作为结果;

SELECT a.paygroup, a.EMPLID, a.FILE_NBR, c.name, e.TLM_STATUS, b.rehire_dt    
as "Emplmnt_Rltd_Dtes-Rehire Date"
FROM PS_EMPLOYMENT b

inner join SYSADM.PS_JOB a
 on a.emplid = b.emplid

inner join SYSADM.PS_PERSONAL_DATA c
  on a.emplid = c.emplid

inner join SYSADM.PS_SMS_SUBSCRB_TBL d
 on a.paygroup = d.SUBSCRIBER_ID

Inner join PORTAL.PS_TS_EMPL_TLM_STATUS e
  on a.emplid = e.emplid

where

b.rehire_dt IS NOT NULL
and d.EFFDT = (select max (d2.effdt) from PS_SMS_SUBSCRB_TBL d2 where      
    d.SUBSCRIBER_ID = d2.SUBSCRIBER_ID)
and e.EFFDT = (select max (e2.effdt) from PORTAL.PS_TS_EMPL_TLM_STATUS e2    
   where e.emplid = e2.EMPLID)
and d.EFF_STATUS <> 'T'

order by a.paygroup, a.emplid

现在xsjs工作正常。

XSJS总是从ajax调用返回exmpty结果集
