  To install in your numbers > Services, double-click menu just the package downloaded .workflow and if necessary give permissions in system preferences > security & privacy.

  To use, just:

  1. Select the cells in the column with duplicate names.
  2. Choose separate copy in numbers > Services menu.

• Update the same column in the same table

  Hello
  
  How do update you a records of column in the same table?
  
  I have purchase_order of the table. Consists of column ID, color, Purchase_No, Sub purchase.
  
  
  < pre >
  
  Create table Purchase_Order)

• Make a column based on another value of the column in the same table

  JDev 11.1.1.6.0

  It may be a silly question but I'm stuck

  I need to conditionally return a column that said Condition is as if the value in the other column of the same table B is equal to F. I should make A column only when this condition is met. I tried the following code:

  	< af:column sortProperty = "PhoneNumber1."
  	sortable = "false".
  	headerText = "#{bindings." A.hints.PhoneNumber1.label}.
  	ID = "c146.
  	rendering = "#{rank." PhoneNumber1ResponseFlag eq 'F'} ">"
  	< af:outputText value = "#{rank." PhoneNumber1}.
  	ID = "ot130" / >
  	< / af:column >
  	< af:column sortProperty = "PhoneNumber1ResponseFlag."
  	sortable = "false".
  	headerText = "#{bindings." B.hints.PhoneNumber1ResponseFlag.label}.
  	ID = "c80" rendered = "true" >
  	< af:outputText value = "#{rank." PhoneNumber1ResponseFlag}.
  	ID = "ot129" / >
  	< / af:column >

  The data presented in the table for the PhoneNumber1ResponseFlag column are F. Still my condition does not work.

  Well, I've finally sorted it myself by managed bean.

  Here are the steps I followed:

  1. Wrote a new bean managed.
  2. Added a Boolean variable called flag and made to true when the "'PhoneNumber1ResponseFlag ' current line attribute is equal to F."
  3. Changing the property made column on this indicator.

• Columns with the same name but different data or precision length.

  DB version: 10 gr 2
  
  In a diagram, I need to find all of the columns with the same name but different or precision data length (if the column is of type number). I know I have to use the USER_TAB_COLS view for this. But I need to find a logic to compare the names of columns and its lengths.

• Question: Is foreign key references to a different column in the same table

  Hello

  I'm not grasp this concept. Would you be able to provide the logic how and why you need to create a foreign key that references a column of the same table?

  For example, referencing the schema, SupervisorNo @ here is a FOREIGN KEY to the "EmpNo" column in the same table.

  EMPLOYEE (EmpNo, title, Fname, Lname, phone, Email, date of birth, sex, salary, HireDate, OutNo, SupervisorNo @)

  
  

  Why would you want to do this and how can it be used? If you are filling out the data in the table, and this constraint is enabled, you will not be able to load whatever it is because the "EmpNo" column will be empty.

  
  

  Any input you can provide me with this would be greatly appreciated. Thank you!

  Self-referential integrity constraints

  Lets say that we have the table emp with emp_no and mgr_no columns.

  Now all managers should also be an employee too. How can I check this when inserting data into this table? I applied auto integrity constraint. It would help me to make sure no handler (doesn't mean no mgr_no) must be registered if this Manager is not an employee of this organization. Which means, I won't be able to enter any mgr_no in the column until and unless that the same employee also is an employee (emp_no from the same table).

• place a select query calculation in a different column in the same table

  How can I put my calculation result in a column named within the same table?

  I have a table called: dgpercentagedatachart

  I use the columns of this dgpercentagedatachart: totalcecrating divided by lowestfeederrating times 100 to get the percentage

  In the query, I gave the result the Alias of the cal

  What I want is to put this result in my application or my calculation (in percentage) in my column "percent" on my table of dgpercentagedatachart vacuum.

  How can I configure this syntax?

  This is the select query, I came with:

  Select dgpercentagedatachart.totalcecrating, dgpercentagedatachart.lowestfeederrating,.

  100.00*dgpercentagedatachart.totalcecrating/dgpercentagedatachart.lowestfeederrating as cal

  of dgpercentagedatachart;

  Here are the results:

  CAL lowestfeederrating Totalcecrating

  8,978 7.48166666666666666666666666666666666667 120

  To change an existing column in a table, you can use the UPDATE or MERGE, instructions like this:

  UPDATE dgpercentagedatachart

  Percentage of VALUE = 100,00 * totalcecrating

  / lowestfeederrating

  ;

  Noramlly, tables is not redundant columns like this.  If percent can always be calculated from other columns, then it is probably better to calculate at run time and store it in the database, where you will have to be updated each time the columns it depends on change.  You can use a view to avoid having to encode them the calculation.

  If you really don't want a column that can be calculated in the same lines other columns, then use a virtual column (if you use Oracle 11 or higher).

  I hope that answers your question.

  If this isn't the case, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.

  If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.

  Explain, using specific examples, how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  Concerning

  Siva,

  What is your version of JDev? What technology you are using (BC4J?)?

  Assuming you are using BC for the model, you tried to create another object view based on query something like

  select distinct gender, gender from your table
  

  and then use this VO for LOV?

• Conflicts of SQL columns on the same table

  I have a table with two columns used for the same purpose. Examples (start_date and career_history_start) (end_date or career_history_end).
  The columns have different (varchar2 and date) data types. The developer has used the data type date (start_date) to write the report and of the use of time even the vachar2 to manully insert date. We decided to use a single (varchar2). Meanwhile, there are differences in the two columns. We will find the difference between the two columns start_date (date) and career_history_start (varchar2).
  
  No idea what query will accomplish this considering they gave different type on the same table?
  
  Here is the description of the table:
  
  career_history / / DESC
  Name of Type Null
  --------------------------- -------- -------------
  CAREER_HISTORY_ID NOT NULL NUMBER (38)
  PERSON_ID NUMBER (38)
  CAREER_HISTORY_START VARCHAR2 (50)
  CAREER_HISTORY_END VARCHAR2 (50)
  CAREER_HISTORY_DESC VARCHAR2 (250)
  CAREER_HISTORY_RECNUM NUMBER (38)
  Start_date DATE
  End_date DATE
  CAREER_HISTORY_ACTIVE_FLAG CHAR (1)
  CAREER_HISTORY_DELETED_FLAG CHAR (1)
  CAREER_HISTORY_UPDATE_TIME TIMESTAMP (6)
  CAREER_HISTORY_UPDATED_BY VARCHAR2 (50)

  The customer doesn't care how the data is stored in the database. He care how it is displayed.

  What happens if your client has another office in a zone schedule differnet and each office needs display their time locally, but the server must store all the time in the same zone. How do they manage that when storing dates as a varchar data type. You get that kind of built-in functionality when you use a date data type

  In its simplest form if the customer is always display the data as a string, and then create a view from top of the table and convert dates in any format the customer prefers and that expose to the client.

  In this way, you get data stored properly and the client allows you to view data in the way they prefer
