I register the schema but don't see any tables

Question

Hi Folks.
Runnning Oracle 11gR2.
I am executing the following command...
DECLARE
  v_schema_name     VARCHAR2(100)   := 'tadig-gen-2.2.xsd';
  v_schemaurl       VARCHAR2(256);
  v_instance        CLOB;
  v_docpath         VARCHAR2(700);
  v_xmlschema       XMLTYPE := XMLTYPE(BFILENAME( 'RTDR_XMLDIR',  v_schema_name ), NLS_CHARSET_ID( 'AL32UTF8') );
BEGIN
  v_schemaurl:= v_schema_name ;  -- 'tadig-gen-2.2.xsd';
  XDB_ANNOTATE_SCHEMA.DISABLEDEFAULTTABLES( v_xmlschema );
  DBMS_XMLSCHEMA.REGISTERSCHEMA
  (schemaurl       => v_schemaurl
  ,schemadoc       => v_xmlschema
  ,local           => FALSE
  ,genTypes        => TRUE
  ,genBean         => FALSE
  ,genTables       => TRUE  );
END;That command exeutes without error.
I then run the following query...
SELECT * FROM User_Xml_Schemasand I get one row returned which shows the schema is registered.
        SCHEMA_URL     LOCAL     SCHEMA     INT_OBJNAME     QUAL_SCHEMA_URL     HIER_TYPE     BINARY     SCHEMA_ID     HIDDEN
tadig-gen-2.2.xsd     NO     <Value Error>     XDonTsa2hMUkjgQLYKTSkxcQ==     tadig-gen-2.2.xsd     CONTENTS     NO     A274EC6B684C5248E040B60A4D293171     NOIf I then execute the following query I get no rows.
SELECT * FROM User_Xml_TablesWhere are my tables?
Any help appreciated.
Kind regards

You made them go away..
XDB_ANNOTATE_SCHEMA.DISABLEDEFAULTTABLES( v_xmlschema );In general in 11.2.0..20 you do not need to generate default tables during schema registration unless the XML Schema has recursive structures or the XML Schema requires the use of out-of-line storage to deal with 1000 column limit..
You can create the table manually using Create Table and XML DB will create the appropriate optimized nested table structures automatically..
