jsp参数错误

Question

基本上我的查询是，

SELECT SEC_ORGANIZATION.description as sec_desc, FIN_COA.name as coa_name, FIN_COST_CENTRE.name as cctr_name, FIN_ANALYSIS.name as analysis_name, FIN_SUBANALYSIS.name as sub_analysis_name, FIN_COA.description as coa_desc, SEC_USER_UPDATE.login_name as update_name, CURRENCY.description as currency_desc, SEC_USER_CREATE.login_name create_name, DOCUMENT_TYPE.description as doc_desc, DOCUMENT_TYPE.name as doc_name, FIN_TRADER.description as trader_desc, AP_REC_POSTED_HDR.trans_no, AP_REC_POSTED_DTL.trans_mode, AP_REC_POSTED_DTL.document_amt as dtl_doc_amt, AP_REC_POSTED_HDR.post_frequency, AP_REC_POSTED_HDR.trans_date as hdr_trans_date, AP_REC_POSTED_HDR.rec_start_date, AP_REC_POSTED_HDR.rec_end_date, AP_REC_POSTED_HDR.document_no hdr_doc_no, AP_REC_POSTED_HDR.rec_lastgen_date, AP_REC_POSTED_HDR.rec_nextgen_date, AP_REC_POSTED_HDR.exchange_rate, AP_REC_POSTED_HDR.document_amt hdr_doc_amt, AP_REC_POSTED_HDR.base_amt hdr_base_amt, AP_REC_POSTED_DTL.base_amt as dtl_base_amt, AP_REC_POSTED_DTL.line_no, AP_REC_POSTED_HDR.organization_id, FIN_YEAR_PERIOD.fin_year, FIN_YEAR_PERIOD.acct_period, AP_REC_POSTED_HDR.remarks hdr_remarks, AP_REC_POSTED_DTL.remarks as dtl_remarks
 FROM   (((((((((((AP_REC_POSTED_HDR AP_REC_POSTED_HDR LEFT OUTER JOIN SEC_ORGANIZATION SEC_ORGANIZATION ON AP_REC_POSTED_HDR.ORGANIZATION_ID=SEC_ORGANIZATION.OBJECT_ID)

 LEFT OUTER JOIN FIN_SUBANALYSIS FIN_SUBANALYSIS ON AP_REC_POSTED_DTL.SUBANALYSIS_ID=FIN_SUBANALYSIS.OBJECT_ID
 WHERE  DOCUMENT_TYPE.NAME='PE'

一切顺利，但是当我输入时，

and ap_rec_posted_hdr.trans_no >= $P{tnoFrom}
and ap_rec_posted_hdr.trans_no <= $P{tnoTo}
and ap_rec_posted_hdr.trans_date >= to_date($P{dtTFrom},'dd-mm-yyyy')
and ap_rec_posted_hdr.trans_date <= to_date($P{dtTTo},'dd-mm-yyyy')
and ap_rec_posted_hdr.posting_date >= to_date($P{finFrom},'dd-mm-yyyy')
and ap_rec_posted_hdr.posting_date <= to_date($P{finTo},'dd-mm-yyyy')
and fin_trader.name >=$P{venFrom}
and fin_trader.name <=$P{venTo}
and sec_user_create.login_name >= $P{cFrom}
and sec_user_create.login_name <= $P{cTo}
  ORDER BY AP_REC_POSTED_HDR.TRANS_NO

它在网页上显示时返回 null 值。

Chi：直接对数据库运行相同的查询。使用您在报告中使用的相同值。

如果得到 null，则查询是正确的。
