• Inventory of the data of all Tables in a database

  Hello
  We do the analysis of the existing data base (Oracle 10 g) and I want to prepare an inventory of the data of all tables in a database that is
  
  1. total number of records in a table
  2. total number of records that have null values in a column
  3. total number of standalone tables IE have no connection with other tables
  etc...
  
  Please let me know if there are tools or query that can do these tasks.
  
  Thank you and best regards,
  Lokesh

  order by owner, table_name, column_id
  

  I added a new column with an alias "get data". This new column will display "NO" is the entire column is zero and 'YES' if there is even a value not null in the column. But caution is that statistics table must be updated to get the correct results.

  Thus, it may be useful to gather current statistics before executing the query.

  Exec dbms_stats.gather_schema_stats or even dbms_stats.gather_database_stats.

• How to convert * all * tables of text in a document?

  Version: Indesign CS 5.5

  I have a massive document that was given to me after be imported into Word, and the person who has imported, it did not convert tables to text (or they tried and it did not work, be it, I have a huge amount of tables that must be not filed).

  I am responsible for the document formatting, and the formatting requirements are to convert all tables in the text document. I was able to batch-process other formatted in the document with the help of find + replace, but I can't seem to find a way to search for all instances of a table in the document and convert all the table set in shape to the text. I can find every table in the search/replace tool using < 0016 >, but I have no idea how, and then delete the table set shaped with the change function.

  I have no text special requirements (standard; tabs for columns and new paragraphs for the lines) and all tables should be converted, regardless of their formatting or content, so it's fairly simple formatting.

  There must be SOME way tot automate this process, it seems incredibly Loïc having to select each table individually and go up to the menu to select "convert table to text... '. ». Any idea is appreciated.

  Click on the text cursor in your text running, and then run this Javascript. WARNING: fully typed memory!

  App.Selection [0].parentStory.tables.everyItem () .convertToText ();

• How to delete all TABLEs in the schema SYS that are created from 09:15?

  Unfortunately a script created a lot of tables in the diagram (= SYS) and bad Tablespace (= SYSTEM).
  
  How can I delete all TABLES that are created inTablespace = SYSTEM and SCHEMA = SYS (in a DDL command)
  respectively for the past 3 hours from 09:15 to 25 Sep 2011?
  
  Alternative: How can I move these tables in another schema (for example ATEST) and Tablespace (USERS)?
  Is this possible with Oracle XE or Oracle Enterprise?
  
  Peter

  You can use ALTER TABLE... MOVE. It offers a TABLESPACE clause, which allows you to choose a different tablespace as target. Refer to the documentation for your version of the database.

• How to create the column of the table for long-form Master detail relationship

  Apex 4.1

  Oracle 11g

  I created a form master detail and see the main table hotel_list and table hotel_mapping as detailed below.

  Hotel_list

  ID HOTEL_NAME

  1 Holiday Inn

  Hotel Hilton 2

  Hotel_mapping

  ID HOTEL_NAME MAPPING_NAME

  1 Inn Holiday Inn Select hotel

  2 holiday hotel Holiday Inn Select

  3 hotel Holiday Inn Holiday Inn Hotel

  4 Hilton Hotel Hilton Hotel chain

  Hotel Hilton 5 HiltonHotel

  Table Hotel_name Hotel_list is a linked table Hotel_mapping

  When I add a line to the Hotel_mapping table for the selected row in the hotel_list table, mapping_name of column is null, therefore impossible to create the relationship between the main table and the secondary table.

  I would like to know, how to create the relationship?

  Thank you very much

  Best regards

  Yong Huang,

  simple step see creating a form detailed master with APEX - Assistant Master retail

  and check how to maintain the relationship between two tables,

  simple return the packaged application «Sample of Masters details»

  and try to understand this concept...

  In your example, use Hotel_list.ID as a foreign key in the table Hotel_mapping

  and maintain the relationship with the column ID...

  and choose the display type of the column Hotel_list.ID in table Hotel_mapping as List(Query Based LOV) select.

  otherwise the best way is to create sample on oracle.apex.com

  I hope this helps...

• How to extract the data in the table in the database

  Hi all

  IM using PHP/MySQL and I use implode () function to store several values of checkboxes that have been selected in the form. Does store the word 'Table' in my database. How can I get back all of each data I've been record before (each of the checked instead of the word Array value)?

  If you don't have that in the database is the Word table, that's all you'll get back out. It sounds like you do not store the information correctly.

  Let's say that your form contains a series of checkboxes, all are called options. For all values, you must add square brackets after the name in the form:

  Sun roof
  
  Satellite navigation
  
  Air conditioning
  

  If the form is submitted using the POST method, the values will be stored in an array called $_POST ['options']. To store in the database, you must check whether the table exists and then use implode ():

  if (isset($_POST['options'])) {
    $options = implode(',', $_POST['options']);
  } else {
    $options = '';
  }
  

  Then insert $options into the database.

• How to get ALL of the 'real' database table in apps/apps

  Hi all

  EBS R12.2

  OEL 6

  I create tables derived from drawing apps and custom drawing.

  When I connect to apps/apps, there are a lot of objects, synonyms, views that point to other tables, synonyms, views of another schema as AP, AR, GL, etc..

  What is confusing is a view contains a table attached, then it is created with a synonym of an another synonyms joined another scheme.

  How can I get the list of actual tables being accessed from these apps objects?

  I would also like to count the lines of ALL the actual tables and get their real value.

• How to dynamically add columns to the table

  Hi all

  I'm new to ADF and need help on sub condition.

  We have created a ViewObject on the EMPLOYEE table that has under columns:

  EMP_ID,

  EMP_NAME,

  DEPARTMENT,

  COST_CENTER,

  BUSINESS_UNIT

  COUNTRY

  GCODE

  We need to create a page in the ADF with employee table to show only below the columns

  EMP_ID,

  EMP_NAME,

  DEPARTMENT,

  COST_CENTER

  Later, if necessary user should be able to add other columns to the page dynamically.

  Can you please advice on how to implement this feature.

  Thank you.

  Kind regards

  Vidya

  Hello.

  There could be a simple solution, which is to use the component PanelCollection.

  Drag ' drop your VO to a page and create a Table with all the attributes.

  For columns that emp_id, emp_name, cost_center, set the Visible property to false.

  Put the PanelCollection component on your page and drag your table inside.

  When you run the page you will see the view menu in the upper left corner of the table above. You can show/hide columns in this menu.

• How to disable specific columns in a table

  Hello world

  There are two buttons in my code (SHIFT and general). When I press the SHIFT key, general column should disable & grey outside, but all three move the columns (Shift1, Shift2, Shift3) should be in an editable state. Like the picture below

  

  and then vice versa case (if I press the general button). Like the picture below

  

  There is no action in the table if the two push button on a high value. I guess that there must be an easy fix, but I just couldn't get there. Please understand it.

  Thanks in advance.

  Use a semi-transparent image on the columns to turn off.  Make the visible decoration or not depending on the State of the Boolean value.   The columns will be always 'on' but will be not clickable.

• How to hide the column in a table in the adf.

  I created the table of the ADF and surround it in the collection of panels, the data in the table from the bean to support variable. Depending on the State, there are a few columns that must hide with the user. I used visible = "false", where the false value will come from backing bean. However the user to the table always have the ability to display the column. Is there any one to hide the column with the user at all times. Fixing the code example:

  < af:column sortable = "false" headerText = "column1" id = "c13" visible = "false" >

  "" < af:outputText value = "{row.columns1} ' id ="ot13"/ >

  < / af:column >
