• CVI suggested help update on 'programming with the Table controls.

  Hello

  May I suggest adding a sentence to the chapter 'Programming with the Table controls', 'Creation and deletion of cells' section help of CVI.

  After the sentence "use the following functions to control the number of rows in a table control...". "I would like to add a suspicion that the number of lines is also affected by (programmatically) adjustment of the height of the table.

  Now that I've discovered, it's obvious ;-)

  Hi Wolfgang,.

  I think you might be misunderstanding this sentence in aid. It does not refer to the size of the table, in regard to the number of lines go in the table. It is in fact the number of real lines exist in the table. And the total number of rows in the table is absolutely not affected by the height of the table.

  If you have saved the file name in the database, it's pretty simple.

  echo '';
  

  Is the same for the box:

  echo '';
  

  If you have saved the image file in the database, it is much more complicated. I recommend you store only the file name in the database.

• When I print a table (multiple pages) the text box under the table seems to be moving under the table and prints with the table of this overlap. My only solution is to push the text box further down the page before printing... Any advice?

  Im having problems shaped a text box so that my table does not print right on top of it. I want it inside of my table (it's 'tems and conditions' budget)

  Any advice would be great.

  I face the same problem as well. Would like to know if there is a better way to get the text box to move with the table instead of the effect that overlap. Have to manually adjust the layout, whenever I want to get a reasonable print of a document (or export it to PDF) seems counterintuitive, especially when it causes the document seem ill-disposed on screen.

  I am running version 3.6.2 of the numbers in the case where that matters.

  Of course, you'll want to change the types of data, etc. as needed.

  I assumed that the XML can contain several "" sections and that each section can contain several entries.

  Thus the XMLTABLE aliasing as 'x' gives information of XML, and supplies the data associated with the XMLTABLE with alias 'y' which gets the multiple authors, which itself section of the XMLTABLE with alias 'z' for each of the article_item.

  CDATA stuff are handled automatically by SQLX (XML functionality integrated into Oracle's SQL)

• Why the hell use nested tables?

  Hello
  I'm boning up on top of the PL/SQL (again) waiting to get a new job.
  I have several years of experience in various roles related to the data, including many used Oracle.
  On the issue of collections, I ask myself, in light of my experience, to find and not for the first time, why the hell would anyone want to do this:
  
  

  create or replace type TEST_TT as table of varchar2(10);
  /
  
  create table TEST_TABLE ( X number
                           ,Y test_tt) 
                           nested table Y store as Y_TABLE;                      

  I really, really, can't think why we want to store data like that. It seems unnecessarily complex, hiding a one-to-many relationship inside TEST_TABLE, which should rather be modeled and implemented as a separate table.
  In addition, there are a lot of tutorials on the collections that tell us how to do the above (in fact I read Feuerstein right now), but nobody seems to tell us WHY we should do it.
  
  Can someone help me out here?
  
  Thank you.
  Jason

  I can't imagine wanting to create a table like this one either (or, if this can help, can Tom Kyte).

  The collections are terribly useful in PL/SQL, when they help you avoid one treatment per line. I can't imagine wanting to integrate into my data model. Frankly, it's much the same with the types of objects - they are quite useful in PL/SQL, but I would never want to create a table in my data model that contained an object.

• How to use Bulk collect in dynamic SQL with the example below:

  My Question is
  
  Using of dynamic SQL with collection in bulkif we pass the name of the table as "to the parameter' function, I want to display those

  It's just a predefined type

  SQL> desc sys.OdciVarchar2List
   sys.OdciVarchar2List VARRAY(32767) OF VARCHAR2(4000)
  

  You can just as easily declare your own collection type (and you are probably better served declaring your own type of readability if nothing else)

  Hello

  ROWID for individual tables can be added as events only if the rule class is set up as a Composite. For all other cases, ROWID is treated as data and they need to be formatted as a string of instances of AnyData or name-value pairs. Your script is to think that you intend to create a composite rule class while you might add ROWID individually. If please, recreate the rule as a composite class and try again. The error message you received is incorrect and has been corrected to indicate that the error is with the format data point past.

  Hope this helps,

  Thank you.

  If you have patterns, it may be easier to work directly on them.

  Here's the idea:

  (1) install "Oracle XML DB manageability Packages", available on the code page for the XML DB sample: http://download.oracle.com/otn/samplecode/xdb_util.zip

  This is a set of utilities which allows us to annotate the XML schemas, to deal with the underlying or storage structure, and (this is the interesting part here) a few views of dictionary to describe the relational XSD structure.

  (it is now an integrated 12 c btw)

  (2) enter these two schemas:

  Start

  () dbms_xmlschema.registerSchema

  schemaURL-online "pacs.002.001.03S2.xsd."

  schemaDoc-online xmltype (bfilename('TEST_DIR','pacs.002.001.03S2.xsd'), nls_charset_id ('AL32UTF8'))

  local-online true

  genTypes-online fake

  genTables-online fake

  enableHierarchy-online dbms_xmlschema. ENABLE_HIERARCHY_NONE

  options-online dbms_xmlschema. REGISTER_BINARYXML

  );

  end;

  /

  Start

  () dbms_xmlschema.registerSchema

  schemaURL-online "SCTCvfBlkCredTrf.xsd."

  schemaDoc-online xmltype (bfilename('TEST_DIR','SCTCvfBlkCredTrf.xsd'), nls_charset_id ('AL32UTF8'))

  local-online true

  genTypes-online fake

  genTables-online fake

  enableHierarchy-online dbms_xmlschema. ENABLE_HIERARCHY_NONE

  options-online dbms_xmlschema. REGISTER_BINARYXML

  );

  end;

  /

  (3) the following query built all the paths of node defined by the main schema (SCTCvfBlkCredTrf.xsd), as well as the namespaces:

  with schema_list (schema_url, schema_owner) as)

  Select 'SCTCvfBlkCredTrf.xsd', 'OTN' from dual

  Union of all the

  Select sd.dep_schema_url, sd.dep_schema_owner

  of schema_list sl

  Join dba_xml_schema_dependency on sd.schema_url = sl.schema_url sd

  and sd.schema_owner = sl.schema_owner

  ),

  namespace_mapping (target_namespace, prefix) as long as)

  Select target_namespace

  , « ns » || ROW_NUMBER() (order target_namespace) as a prefix

  of user_xml_schema_namespaces

  where schema_url in (select schema_url from schema_list)

  ),

  () schema_nodes

  is_attr

  node_name

  max_occurs

  element_id

  parent_element_id

  target_namespace

  schema_url

  ) as)

  Select 0

  element_name as node_name

  xmlcast)

  XMLQUERY ('/ XS: ELEMENT / ' @maxOccurs passing returning content element)

  as varchar2 (10)

  )

  element_id

  parent_element_id

  target_namespace

  schema_url

  of user_xml_schema_elements

  where schema_url in (select schema_url from schema_list)

  Union of all the

  Select 1

  attribute_name as node_name

  null

  null

  element_id

  target_namespace

  schema_url

  of user_xml_schema_attributes

  where schema_url in (select schema_url from schema_list)

  )

  Select the level

  sn.node_name

  sn.max_occurs

  connect_by_isleaf as is_leaf

  sys_connect_by_path)

  -case when ns.prefix is not null and is_attr = 0 then ns.prefix | ':' end |

  -case when sn.is_attr = 1 then ' @' end |

  SN. NODE_NAME

  , '/'

  ) as xpath

  -, target_namespace

  of schema_nodes sn

  outer join ns namespace_mapping let ns.target_namespace = sn.target_namespace

  Connect prior sn.element_id = sn.parent_element_id

  Start with sn.schema_url = "SCTCvfBlkCredTrf.xsd".

  and sn.parent_element_id is null

  In fact, you would be generally extracted from mapping data in a separate query so that you can use it to build the dynamic with XMLNamespaces clause of the namespace.

  NB1: Also note that not all roads are needed, only those which IS_LEAF = 1 or MAX_OCCURS = "unlimited" or MAX_OCCURS > '1', then you can add a filter predicate in the query directly.

  NB2: The query does support all the features of XSD, for example, I've relied on the default behavior for attributes 'element_form_default' and 'attribute_form_default '.
