我有跟随我想用oracle生成的xml。
<Component ID="600564" asmid="1" def="FactSheet" type="Document">
<Profile>
<Port_ID>182</Port_ID>
<Inception_Date>31 Dec 1998</Inception_Date>
</Profile>
<AverageAnnualReturns>
<TableData>
<Item>
<ClassID>33</ClassID>
<ClassName>A1USD</ClassName>
<Superscript>2</Superscript>
<Superscript_TCE/>
</Item>
<Item>
<ClassID>45</ClassID>
<ClassName>I1EUR</ClassName>
<Superscript>1,2</Superscript>
<Superscript_TCE/>
</Item>
</TableData>
<SuppressLifeColumn>Yes</SuppressLifeColumn>
<SuppressBenchColumn10yr>No</SuppressBenchColumn10yr>
<SuppressBenchColumn5yr>No</SuppressBenchColumn5yr>
<SuppressBenchColumn3yr>No</SuppressBenchColumn3yr>
<SuppressBenchColumn1yr>No</SuppressBenchColumn1yr>
</AverageAnnualReturns>
</Component>
查询个人资料如下
SELECT PCR.PORT_ID,
to_char(p.port_start_dt, 'dd Mon yyyy') as INCEPTION_DATE
FROM edp_admin.PORT_CLASS_REPORT PCR
JOIN edp_admin.PORTFOLIO p on (PCR.PORT_ID = P.PORT_ID and PCR.CLASS_ID = P.BASE_CLASS_ID)
where PCR.PORT_ID = 182 AND PCR.REPORT_ID = 472
查询AverageAnnualReturn如下
SELECT distinct MPR.PORT_ID,
MPR.CLASS_ID,
MPR.CLASS_NAME,
PCR.VALUE_NUM3 as RANK,
NVL (NC.SUPERSCRIPT_TEXT,' ') as SUPERSCRIPT_TEXT
FROM EDP_ADMIN.SYSTEM_VALUE PCR
LEFT JOIN EDP_ADMIN.MPR_MIL_VIEW MPR ON (PCR.VALUE_NUM1 = MPR.PORT_ID AND PCR.VALUE_NUM2 = MPR.CLASS_ID AND MPR.CLASSIF_ID = 206)
LEFT JOIN EDP_ADMIN.PORT_CLASS_YIELD PCY ON (PCR.VALUE_NUM1 = PCY.PORT_ID AND PCR.VALUE_NUM2 = PCY.CLASS_ID AND MPR.PROFILE_DATE = PCY.PORT_CLASS_YIELD_DT AND PCY.YIELD_ID = 6)
LEFT JOIN EDP_ADMIN.PORTFOLIO_CLASS PC ON (PCR.VALUE_NUM1 = PC.PORT_ID AND PCR.VALUE_NUM2 = PC.CLASS_ID)
LEFT JOIN EDP_ADMIN.PORT_CLASS_MKT_PRICE PCMP ON (PCR.VALUE_NUM1 = PCMP.PORT_ID AND PCR.VALUE_NUM2 = PCMP.CLASS_ID AND PCMP.MKT_PRICE_ID = 12 AND MPR.PROFILE_DATE = PCMP.PORT_CLA_MKT_PRICE_PER_END_DT)
LEFT JOIN (SELECT DISTINCT R1.PORT_ID, R1.CLASS_ID, R1.PORT_CLASS_EXP_RAT_VALUE, R1.PORT_CLASS_EXP_RAT_DT FROM edp_admin.Port_Class_Expense_Ratio R1 INNER JOIN (SELECT DISTINCT PORT_ID, CLASS_ID, MAX(PORT_CLASS_EXP_RAT_DT) as MONTH_END_DATE FROM EDP_ADMIN.PORT_CLASS_EXPENSE_RATIO GROUP BY PORT_ID, CLASS_ID ) R2 ON (R1.PORT_ID = R2.PORT_ID AND R1.CLASS_ID = R2.CLASS_ID AND R1.PORT_CLASS_EXP_RAT_DT = R2.MONTH_END_DATE) ) PCER ON PCR.VALUE_NUM1 = PCER.PORT_ID and PCR.VALUE_NUM2 = PCER.CLASS_ID
LEFT JOIN EDP_ADMIN.FN_MIL_FS_CONCAT_NOTES_VIEW NC ON NC.PORT_ID = PCR.VALUE_NUM1 AND NC.CLASS_ID = PCR.VALUE_NUM2 AND NC.HYPO_TYPE = PCR.VALUE_CHAR1
WHERE PCR.CODE = 'MIL_FS_PERF_CONFIG' AND PCR.VALUE_NUM1 IN (182) AND PCR.VALUE_CHAR1 = 'UK' ORDER BY RANK
我尝试使用oracle sql函数生成xml，如下所示
select dbms_xmlquery.getxml(sql for profile) from dual
但它会生成两个额外的xml节点rowset和row，如下所示
<?xml version = '1.0'?>
<ROWSET>
<ROW num="1">
<PORT_ID>182</PORT_ID>
<INCEPTION_DATE>31 Dec 1998</INCEPTION_DATE>
</ROW>
</ROWSET>
其他方式是
select xmlelement("Component",xmlattributes('600564' as ID,
'1' as asmid,
'FactSheet' as def,
'Document' as type
),
xmlagg(
xmlelement("Profile")
)
)from dual
它生成如下结构
<Component ID="600564" ASMID="1" DEF="FactSheet" TYPE="Document"><Profile></Profile></Component>
BUt我不打算如何在profile节点下填充数据，然后averageannualreturns
答案 0 :(得分：2)
您可以使用子选择来获取profile和averageannualreturns节点的数据。例如：
select xmlelement("Component",
xmlattributes('600564' as ID,
'1' as asmid,
'FactSheet' as def,
'Document' as type
),
(
SELECT XMLELEMENT("Profile",
XMLFOREST(
'example_port' AS "Port_ID",
'30/11/2016' as "Inception_Date"
)
)
FROM dual
)
) from dual;
我相信这是你需要的东西（尽管我没有你要测试的桌子）：
select xmlelement("Component",
xmlattributes('600564' as ID,
'1' as asmid,
'FactSheet' as def,
'Document' as type
),
(
SELECT XMLELEMENT("Profile",
XMLFOREST(
PCR.PORT_ID AS "Port_ID",
to_char(p.port_start_dt, 'dd Mon yyyy') as "Inception_Date"
)
)
FROM edp_admin.PORT_CLASS_REPORT PCR
JOIN edp_admin.PORTFOLIO p on (PCR.PORT_ID = P.PORT_ID and PCR.CLASS_ID = P.BASE_CLASS_ID)
where PCR.PORT_ID = 182 AND PCR.REPORT_ID = 472
),
(
SELECT XMLELEMENT("AverageAnnualReturns",
XMLELEMENT("TableData",
XMLAGG(
XMLELEMENT("Item",
XMLFOREST(
MPR.CLASS_ID AS "ClassID",
MPR.CLASS_NAME AS "ClassName",
NVL (NC.SUPERSCRIPT_TEXT,' ') AS "SuperScript",
NULL AS "SuperScript_TCE"
)
)
)
),
XMLFOREST(
'Yes' AS "SupressLifeColumn",
'No' AS "SupressBenchColumn10yr",
'No' AS "SupressBenchColumn5yr",
'No' AS "SupressBenchColumn3yr",
'No' AS "SupressBenchColumn1yr"
)
)
FROM EDP_ADMIN.SYSTEM_VALUE PCR
LEFT JOIN EDP_ADMIN.MPR_MIL_VIEW MPR ON (PCR.VALUE_NUM1 = MPR.PORT_ID AND PCR.VALUE_NUM2 = MPR.CLASS_ID AND MPR.CLASSIF_ID = 206)
LEFT JOIN EDP_ADMIN.PORT_CLASS_YIELD PCY ON (PCR.VALUE_NUM1 = PCY.PORT_ID AND PCR.VALUE_NUM2 = PCY.CLASS_ID AND MPR.PROFILE_DATE = PCY.PORT_CLASS_YIELD_DT AND PCY.YIELD_ID = 6)
LEFT JOIN EDP_ADMIN.PORTFOLIO_CLASS PC ON (PCR.VALUE_NUM1 = PC.PORT_ID AND PCR.VALUE_NUM2 = PC.CLASS_ID)
LEFT JOIN EDP_ADMIN.PORT_CLASS_MKT_PRICE PCMP ON (PCR.VALUE_NUM1 = PCMP.PORT_ID AND PCR.VALUE_NUM2 = PCMP.CLASS_ID AND PCMP.MKT_PRICE_ID = 12 AND MPR.PROFILE_DATE = PCMP.PORT_CLA_MKT_PRICE_PER_END_DT)
LEFT JOIN (SELECT DISTINCT R1.PORT_ID, R1.CLASS_ID, R1.PORT_CLASS_EXP_RAT_VALUE, R1.PORT_CLASS_EXP_RAT_DT FROM edp_admin.Port_Class_Expense_Ratio R1 INNER JOIN (SELECT DISTINCT PORT_ID, CLASS_ID, MAX(PORT_CLASS_EXP_RAT_DT) as MONTH_END_DATE FROM EDP_ADMIN.PORT_CLASS_EXPENSE_RATIO GROUP BY PORT_ID, CLASS_ID ) R2 ON (R1.PORT_ID = R2.PORT_ID AND R1.CLASS_ID = R2.CLASS_ID AND R1.PORT_CLASS_EXP_RAT_DT = R2.MONTH_END_DATE) ) PCER ON PCR.VALUE_NUM1 = PCER.PORT_ID and PCR.VALUE_NUM2 = PCER.CLASS_ID
LEFT JOIN EDP_ADMIN.FN_MIL_FS_CONCAT_NOTES_VIEW NC ON NC.PORT_ID = PCR.VALUE_NUM1 AND NC.CLASS_ID = PCR.VALUE_NUM2 AND NC.HYPO_TYPE = PCR.VALUE_CHAR1
WHERE PCR.CODE = 'MIL_FS_PERF_CONFIG' AND PCR.VALUE_NUM1 IN (182) AND PCR.VALUE_CHAR1 = 'UK' ORDER BY RANK
)
) from dual;
使用appendChildXML和plsql的解决方案：
DECLARE
lComponentXML xmltype;
lProfileXML xmltype;
BEGIN
--generate the component xml
select xmlelement("Component",
xmlattributes('600564' as ID,
'1' as asmid,
'FactSheet' as def,
'Document' as type
)
)
INTO lComponentXML
FROM dual;
--generate the profile xml
SELECT XMLELEMENT("Profile",
XMLFOREST(
PCR.PORT_ID AS "Port_ID",
to_char(p.port_start_dt, 'dd Mon yyyy') as "Inception_Date"
)
)
INTO lProfileXML
FROM edp_admin.PORT_CLASS_REPORT PCR
JOIN edp_admin.PORTFOLIO p on (PCR.PORT_ID = P.PORT_ID and PCR.CLASS_ID = P.BASE_CLASS_ID)
where PCR.PORT_ID = 182 AND PCR.REPORT_ID = 472;
--append the profile xml to the component
lComponentXML := lComponentXML.appendChildXML('//Component',lProfileXML);
END;
