![]() I gather that since it involves the repetition I might need to do some sort of PL/SQL programming but I definitely need some help here to build that ad also a way to extract the information. I would appreciate if you can help me with that: However each RI4 and RI6 tag has different data. It treats a NULL expression and NULL search as equal (so NULL NULL). The following example extracts the value of the /Warehouse/Dock node of the XML path of the warehousespec column in the sample table oe. As I mentioned above, the Oracle DECODE function is an exception to other functions in how it handles NULL values. I have truncated the data but there is a repetition of tag and consequenty internal to that of RI6 tag. 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). What we will see in this article XML Parsers for processing data How to process XML data with Oracle PL/SQL with multiple scenarios. The article will give information about how to do the xml file processing with multiple scenarios. I need to extract the information in tag and also from tag. Oracle has introduced a separate in built package for processing the xml data named XMLDB package. I have a column whose data is of xml type (clob data). I need to extract the information in tag and also from tag.You can then use XMLTable to extract the attributes as traditional rows and columns.I need some help with the following. How to extract a value from sql column-xml clob data sql enthusiast edited Hi Guys, I need some help with the following. 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() ORA-22806: not an object or select xmltype(e.x).extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() 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') 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. Well, you know - this is alot like storing a DATE in a number, a number in a string. OracleCommand cmd new OracleCommand ('', con) // Set the XML command type to query. Same on xmltype column but they do not work on a clob. I have seen various examples of doing the use the type that most closely models your data. Please show me how to extract the value out of an xml tag on a clob using a sql query. You spend lots of time converting strings into XML documents over and over - and the data isn't validated Just substitute NUMBER for XML and VARCHAR for CLOB Or DATE for XML and NUMBER for CLOB Or for XML and for CLOB same argument.However the same code works in a PL/SQL block where i convert the request_detail (clob) to sys.xmltype before using the extract Select e.request_detail.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() Sql > select e.request_detail.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() I tried the following but am getting an error XML Encoding in XMLTYPE column in Oracle DB Ask Question Asked 5 years ago Modified 5 years ago Viewed 11k times 3 I have a table created like this: create table b (data timestamp, value XMLTYPE) I run this script in TOAD 12.6 to store a XML in the table. I need a query to extract the value in the Group_type tag. PRDATA ENGINEERING ASSET MANAGEMENTSCS-FCATRoland Roy For example the clob could have a value of ![]()
