xmltype

问题 I am trying to extract an XMLTYPE column from an Oracle table using JDBC. I have the query: select "XML_FILE" FROM "TABLE_NAME" and when I run the query in the Oracle SQL Developer, it returns back all the XMLTYPE rows completely fine. But, when I run the following Java code, and run the same query, I always get "null" returned for every column. I'm not sure what could be going wrong and I've tried doing many different things, but nothing has been working. Important note - the XMLTYPE fields

问题 I have a table (AKADMIN) with an XMLTYPE column which name is XML. I would like to use the getClobVal() with this column. select t.xml.getClobVal() /**/ , t.xml.getClobVal() -- , t.xml.getClobVal() as clobval , t.xml.getClobVal() from akadmin t where ROWID = 'AAAQc6AAIAAAADDAAA' ; In the resultset the first 4 column give CLOB type, but the fifth column XMLTYPE. I have to type any comment or alias after getClobVal() to correct (CLOB) type of the result. Why? Another issue, when I leave the

问题 The following is an example of what I am trying to do: WITH xdata AS (SELECT 1 AS a_id, xmltype ('<a> <b> <b_id>1</b_id> <val>2</val> </b> <b> <b_id>1</b_id> <val>3</val> </b> </a>') AS xcol FROM DUAL UNION ALL SELECT 2 AS a_id, xmltype ('<a> <b> <b_id>3</b_id> <val>5</val> </b> <b> <b_id>4</b_id> <val>4</val> </b> </a>') AS xcol FROM DUAL) SELECT a_id, XMLCAST ( XMLQUERY ('sum($doc/a/b/val/text())' PASSING xcol AS "doc" RETURNING CONTENT) AS INTEGER) b_val FROM xdata GROUP BY a_id, xcol;

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . From XML to list of paths in Oracle PL/SQL environment shows how to list all the XPATHs of each XML element in an XML document and their corresponding values. My Question is how to list all the XPATHs of the XML elements and the XPATHs of their attributes and the corresponding values? Oracle Setup : CREATE TABLE

问题 I outlined a solution to writing/reading to an Oracle XMLType column for Oracle 11g (specifically 11.2.0.1) if the XMLType column is stored as a CLOB, which is the default for 11.2.0.1. REFERENCE ANSWER: Using oracle XMLType in a java spring hibernate scenario In SQLDeveloper, if you view the SQL tab within a table definition (table DDL) it defines the XML columns storage in 11.2.0.1 like this: XMLTYPE COLUMN "ATTRIBUTE_XML2" STORE AS BASICFILE CLOB Problem: In Oracle 11.2.0.2, the default

问题 I have xml document <d> <r>a<b</r> </d> and I want to update it to <d> <r>a<b or c>d</r> </d> using updateXML statement. Executing select updateXML(xmltype('<d><r>a<b</r></d>'), '/d/r[1]/text()', 'a<b or c>d') from dual; returns <d> <r>a&lt;b or c&gt;d</r> </d> It is not good because of "&". Executing select updateXML(xmltype('<d><r>a<b</r></d>'), '/d/r[1]/text()', 'a<b or c>d') from dual; throws ORA-31067 XML nodes must be updated with valid nodes and of the same type. How can I reach

问题 I've written simple Oracle queries to extract XMLTYPE data before, but this XML is different - I need to pull information from attributes, child elements, and their respective attributes. I also would like to write an INSERT statement as well (preferably one that is able to find the highest option value and add 1). Consider the following XML: <metadata> <fields> <field name="cusInt01" label="Reference point"> <option value="1">CB</option> <option value="2">CF</option> <option value="3">DF<

问题 I am running Oracle 11.2.0.3 and am attempting to create a workable UserType that maps XMLType or SQLXML columns. Existing solutions found online all have two problems: XMLType values are LOB values, so they must be free() prior to Connection.close() or they will leak both database resources and heap memory in Java. XML values fetched from these columns are connected objects; unless they are copied via a deep copy, they are gone after the connection closes. So, I wrote this classes at the
