![]() Passing XMLType.createXML(SYS.DBMS_XMLGEN.getXML('select name from appname'))Ä«ut in this case the conversion to XML is a bit pointless. 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 ÄBMS_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. Which return back the output same as "Oracle & Database"Ä«ut i need output as "Oracle & Database" Syntax: DECODE ( expression, search, result, search, result. Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). In the body, insert detailed information, including Oracle product and version. ![]() Enter a title that clearly identifies the subject of your question. The DECODE function is supported in the various versions of the Oracle/PLSQL, including, Oracle 12c, Oracle 11g, Oracle 10g and Oracle 9i. Select a discussion category from the picklist. It is used to work as an IF-THEN-ELSE statement. Step 1 : You can create separate column of XMLType in table level to store the XML type data. ![]() but it return as "Oracle & Database"Ä«elow 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 DECODE is an advanced function that the Oracle database supports. But Here i would like to give you some important examples for the same. I have used the DBMS_XMLGEN to make it XML Complaint and trying to using extractvalue to get the value. This won't work as EXTRACTVALUE can return value for only one node and you have several ones for this path. What i need to do is get the output in XML compliant format. I have table name "AppName" select NAME from AppName CREATE TABLE xmltab ( Filename varchar2 (100), xmldata XMLTYPE ) Next, insert data from Test.xml into xml.tab by using the following command. 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. First, create a table in Oracle that includes a column with data type XMLTYPE. OracleCommand cmd new OracleCommand ('', con) // Set the XML command type to query. I need to query a table and display the column value by transforming escape character into XML format First approach: Load the XML file into an XML table and then parse it. Scripting on this page enhances content navigation, but does not change the content in any way.I have a requirement. The following example extracts the value of the /Warehouse/Dock node of the XML path of the warehouse_spec column in the sample table oe.warehouses:Ä®XTRACT(warehouse_spec, '/Warehouse/Docks') "Number of Docks"Ĭompare this example with the example for EXTRACTVALUE, which returns the scalar value of the XML fragment. This argument must resolve to a VARCHAR2 value that specifies a default mapping or namespace mapping for prefixes, which Oracle Database uses when evaluating the XPath expression(s). The optional namespace_string is required if the XML you are handling uses a namespace prefix. If you omit the initial slash, then the context of the relative path defaults to the root node. The following example extracts the value of the /Warehouse/Dock node of the XML path of the warehousespec column in the sample table oe. You can specify an absolute XPath_string with an initial slash or a relative XPath_string by omitting the initial slash. This argument must resolve to a VARCHAR2 value that specifies a default mapping or namespace mapping for prefixes, which Oracle Database uses when evaluating the XPath expression(s). It applies a VARCHAR2 XPath string and returns an XMLType instance containing an XML fragment. Below is query to transform to XML format select ( 'select NAME from APPName ') XMLout from dual ' ![]() However, Oracle recommends that you use the XMLQUERY function instead. It is still supported for backward compatibility. The EXTRACT (XML) function is deprecated.
