대용량 xml 데이터를 단일 테이블에 삽입

Question

xmltable에서 INSERT INTO .. ​​SELECT를 수행하려고했습니다. 이 삽입이 없으면 프로 시저가 성공적으로 (빠르게) 완료되지만이 코드가 9999 행을 삽입하기 위해 포함되면 완료까지 시간이 걸리지 만 테이블에는 레코드가 없습니다.

위의 파일이 PMTRELINFO9999의 최대까지 PMTRELINFO001있다. 필자는 INDIVID와 같은 다른 데이터를 가져 오지 않고 대상 테이블에 삽입하기 만하면됩니다. 내 코드는 아래와 같습니다.

INSERT INTO ach_addenda(ach_id,rmr_number,rmr_code,invoice_number,rmr_paid_amt,rmr_orig_amt,rmr_disc_amt,rmr_date,ref_code,ref_id,ref_name,ref_instructions,adx_instructions,

효율성을 높이고 삽입 작업을하는 데 도움이되는 제안 사항. 추가 힌트가있는 삽입을 시도했지만 차이는 없습니다.

귀하의 질문에 3 과실이 있습니다.

XMLTABLE (
        xmlnamespaces (
         default 'http://www.xyzcompany.com/Canonical', 
         'http://xyzcompany.com/PmtInfo' AS "pmt", 
         'http://xyzcompany.com/CommonTypes' AS "cmn", 
         'http://www.w3.org/2001/XMLSchema-instance' AS "xsi"), 
        '/xyzcompany/Pmt/pmt:Payments/pmt:PayInfo/pmt:Single/pmt:SingAddInfo[contains(upper-case(cmn:AddInfoCmpType),"PMTREL")]' 
        PASSING a). 

1) 루트 NOOD하지 xyz

2) http://www.xyzcompany.com/Canonical는 기본 네임 스페이스 및 연산자를 좋아는 XQuery에서 그런 식으로 default 'http://www.xyzcompany.com/Canonical',

3) cmn:AddInfoCmpType = "PMTREL%"하지 거기 장식한다 xyzcompany입니다. pmt:SingAddInfo[contains(upper-case(cmn:AddInfoCmpType),"PMTREL")]
