sql_mode=oracle does not support XMLAGG(), XMLELEMENT() and EXTRACT() XML functions

    XMLWordPrintable

    Details

      Description

      Most oracle applications use xml aggregation functions like XMLAGG() followed by identifying the XML elements XMLELEMENT() and then calling the EXTRACT() method to extract. This is important for Oracle migrations and is in use by many projects which are using XML in Oracle and are trying to Migrate to MariaDB.
