Nest each set of elements in their own GROUP (or whatever) element. This makes it tricky to identify the corresponding BUS_UNIT_ACRN for a given GROUP_ID. TNS for Solaris: Version 9.2.0.5.0 - Productionīoth the GROUP_ID elements have the same parent. Oracle9i Enterprise Edition Release 9.2.0.5.0 - Production LPX-00241: entity reference is not well formed ORA-19202: Error occurred in XML processing SQL> insert into t values ('test &test') XMLTYPE(T.CL).EXTRACT('/ROOT/TEXT()').GETSTRINGVAL() SQL> select xmltype(t.cl).extract('/root/text()').getStringVal() SQL> insert into t values ('test & test') XMLTYPE(E.X).EXTRACT('/REQUEST_DETAIL/GROUP_TYPE/TEXT()').GETSTRINGVAL() Step 1 : You can create separate column of XMLType in table level to store the XML type data. ORA-22806: not an object or select xmltype(e.x).extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() Below is query to transform to XML format select ( 'select NAME from APPName ') XMLout from dual ' oracle select xml decode

Select e.x.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() Here is a temporary solution - long term, use the right type for the create table t ( x clob ) ġ row select e.x.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() You'll spend the rest of your life converting - and if the data in the clob isn't actually XML (well formed enough), you won't find out until you need it (just like when that string that should be a number contains 'hello world') Well, you know - this is alot like storing a DATE in a number, a number in a string. Same on xmltype column but they do not work on a clob. I have seen various examples of doing the

Please show me how to extract the value out of an xml tag on a clob using a sql query.

Oracle select xml decode code#

However the same code works in a PL/SQL block where i convert the request_detail (clob) to sys.xmltype before using the extract cmd.BindByName true // Bind values to the parameters in. cmd.CommandText 'select from emp e where e.empno :empno' // Set command properties that affect XML query behaviour. cmd.XmlCommandType OracleXmlCommandType.Query // Set the SQL query. Select e.request_detail.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() OracleCommand cmd new OracleCommand ('', con) // Set the XML command type to query. Sql > select e.request_detail.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() I tried the following but am getting an error I need a query to extract the value in the Group_type tag. PRDATA ENGINEERING ASSET MANAGEMENTSCS-FCATRoland Roy Passing XMLType.createXML(SYS.DBMS_XMLGEN.getXML('select name from appname'))īut in this case the conversion to XML is a bit pointless.For example the clob could have a value of If you already had the XMLType, or wanted it in that format for some other reason, you could use an XMLQuery instead of extractValue: select xmlquery('/ROWSET/ROW/NAME/text()' Or to 1 (ENTITY_DECODE) to do the reverse operation and decode: select dbms_nvert('Oracle & Database', 1) from dual ĭBMS_XMLGEN.CONVERT('ORACLE& DATABASE',1) The second argument defaults to ENTITY_ENCODE, and you can either set that explicitly (using the underlying value 0 in plain SQL) to encode: select dbms_nvert('Oracle & Database', 0) from dual You're doing more work than you need to dbms_xmlgen has a convert() function, which escapes special characters (entities) by default: select dbms_nvert(name) from appname How can i get this output using DBMS_XMLGEN or is there is any easy way. FROM testxml t, XMLTable ( '//record' passing t. Direct CLOB projection is supported starting with 11.2.0.2, using XMLTable or XMLCast/XQuery functions (extractvalue, extract, xmlsequence are deprecated now) : SELECT x. Which return back the output same as 'Oracle & Database'īut i need output as 'Oracle & Database' Answer: You use the extractvalue procedure for extracting XML from a CLOB in Oracle SQL select statements. First approach: Load the XML file into an XML table and then parse it First, create a table in Oracle that includes a column with data type XMLTYPE.

but it return as 'Oracle & Database'īelow is query to transform to XML format select SYS.DBMS_XMLGEN.getXML( 'select NAME from APPName ') XML_out from dualĪnd then i try to extract the Name select extractvalue( XMLType.createXML(SYS.DBMS_XMLGEN.getXML( 'select NAME from APPNAme' )),'/ROWSET/ROW/NAME') XML_out from dual I have used the DBMS_XMLGEN to make it XML Complaint and trying to using extractvalue to get the value. What i need to do is get the output in XML compliant format. I have table name 'AppName' select NAME from AppName

I need to query a table and display the column value by transforming escape character into XML format
