• What are the best practices for creating only time data types, and not the Date

  Hi gurus,

  We use 12 c DB and we have a requirement to create the column with datatype of time only, if someone please describe what are the best practices for the creation of this.

  I would strongly appreciate ideas and suggestions.

  Kind regards
  Ranjan

  Hello

  How do you intend to use the time?

  If you are going to combine with DATEs or timestamps from a other source, then an INTERVAL DAY TO SECOND or NUMBER may be better.

  Will you need to perform arithmetic operations on time, for example, increase the time to 20%, or take an average?   If so, the NUMBER would be preferable.

  You are just going to display it?  In this case, DAY INTERVAL in SECONDS, DATE or VARCHAR2 would work.

  As Blushadow said, it depends.

  This query actually belongs to SQL and PL/SQL Forum. Please take care and post in the correct forum.

  In any case...
  CREATE TABLE TEMPORARY global is a DDL command. Once created TWGS will exist until he FELL. Try to create a TWG with the same name will fail. just like any table, view, etc. See http://docs.oracle.com/cd/B28359_01/server.111/b28310/tables003.htm#i1006400

  a: you can create a TWG once and use/re-use it anywhere in your code.
  (b) as it is a DDL you can not use in the DECLARE section. You can use BEGIN and EXCEPTION.

  See you soon,.

• What to fill in 'field of the temporary table' for global temporary tables?

  Hello

  I use the Data Modeler 4.0.1.836 and everything that I put in the box 'the scope of the table temp' for a global temporary table doesn't seem to affect the DDL script about the ON COMMIT PRESERVE/DELETE the LINES option. The script poster ON COMMIT PRESERVE ROWS always anything.

  Yet, some of my temporary tables must be created as ON COMMIT DELETE ROWS.

  Using the Data Modeler wrote about it:

  Scope of the temporary Table:

  For a class as a temporary table, you can specify a scope, such as the Dimension or the Session.

  Not sure what 'Dimension' has to do with the scope here, but it makes no difference.

  I tried to put 'Session', 'Dimension', 'Operation', but no luck. So what is the text for the script generate ON COMMIT DELETE ROWS?

  Thank you

  Hello

  The temporary Scope of Table property (on page Types of Classification of the table properties dialog box) is purely documentary.

  To set ON COMMIT DELETE ROWS you must expand the browser for the relational model and find the node for the relevant Oracle physical model.  If you develop it you will find an entry there for your Table. Double-click on that to get the physical model properties dialog box for your table, and you will find a "Temporary" facility that has options (Preserve Rows), YES (Delete Rows) YES or no.

• What is the best, collection, or Global Temp tables?

  Hi all

  I have to deal with 1 lakh record in plsql, storage can I choose? Global temporary tables or plsql collection?

  Please advice, performance is very important!

  In other words, you will probably use only the data in the remote database through SQL - for example he will join your tables, filtering, etc.

  In one such case will consider a TWG or materialized view.

  A collection (structure memory PL/SQL) manipulated via a SQL (operating separately from the PL/SQL engine) engine, would usually be a very bad choice, performance, and scalability ito usability.

• Global temporary table Vs Table permanently to manipulate the transaction data

  Hi all
  
  Version of database - 10.2.0.4
  
  We need handle transactions, data in a table and put in an intermediate table (ie): to replicate the data in the tables of a schema of staging of the tables in the schema. Get info on transactions and handling.
  Can you please indicate which one of the below is the best option.
  
  Option 1:
  Create a global temporary table, each running process.
  
  Option 2:
  Create a table permanently and delete lines at the beginning of the process.
  
  Job expects every 5 minutes
  
  Thank you and best regards,
  Rakesh

  If data are transient and must be written to the disk (I'm not sure I follow your explanation for why written data on the disk are necessary - you have to touch table large transaction each time to fill the intermediate table) using a global temporary table. At least, you'll reduce the cost of writing the data to disk by generating less recovery.

  But ideally, you would not write the data on the drive at all and would be able to do it in SQL.

• What is the best way to deal with a 'Implicit coercion' in a table to a sprite?

  Hi all!

  With the continued support of this forum, I'm getting closer to have a programme of work. I can't wait to be able to help others like me once I've finished learning the ropes of AS3.

  I'll briefly explain what I want to achieve and then followed with my question.

  Background

  I created a random number of 12 x 9 grid that fills each cell with an image, based on the numeric value of each cell. I also have a random play button that makes random numbers in the grid. The problem I am running became my click event of button to erase the current images off the grid in order to allocate the new (for example by removing the objects display battery in order to place the new ones in the same places).

  Question

  My question is this: what is the best way to manage an implicit constraint from a table to a sprite? I pasted my complete code below so that you can see how the functions are supposed to work together. My sentence is apparently not being able to use a value from array with a sprite (sprite represents the real layout of the grid on the pile of display while the table starts as a number that is assigned an image that must be transmitted to the sprite).

  Any help with this is greatly appreciated. Thank you!

  If you want to have an array of Sprites that you later clear that is fine. But this does not mean that your function should return to it.

  You need your function to return the sprite so that you can add it to the display list and everything what you need.

  So just have the function get Sprite, push it in the "toBeClearedInTheFutureArray" and then return a reference to the currently acquired sprite.

• order of the lines of the global temporary table

  I have a global temporary table "TMP_PAYMENT_ANNUITY" and I insert records in there with loop for each iteration of loop insert a row in the table.
  Now, I'm back records inserted user with cursor in this way:

     open o_annuity_payments for 
        select * from TMP_PAYMENT_ANNUITY;

  Can I be sure that the slider will have records in exactly the same order as inserted loop them?
  Or do I also insert rownumber column of my table that I filled with the loop iteration variable, and I'll be back slider like this:
  

     open o_annuity_payments for 
        select * from TMP_PAYMENT_ANNUITY
         order by ROWNUMBER;

  Currently, I have "ROWNUMBER"-column in the table, but maybe I should create then? ".
  The question is about the order of the rows, how this order will be without "in order to" - clause?

  1. This approach/solution is easier to read for other developers. Ugly hierarchical query with the function LAG is difficult to read and edit.

  I agree with you! It's one of the reasons when you should stop developing very sophisticated SQL statements. Even if the performance is slightly better.

  2-hierarchical-feature in sql is always slow and friendly error.

  I don't think that a hierarchical solution is necessary. but it may depend on your version of Oracle (think MODEL clause).

  3. it is easy to implement the "temporary table solution." with complex sql construction will be time-consuming and bug-friendly and complex.
  3. I'm not sure the question of perfomance, here I may be wrong, I test/compare.

  I never would implement it WITHOUT a prescription by cluase. Why depend on such a solution?
  One of your strong points would improve maintainability. It is against this requirement.
  Imagine this happening, for example, when another developer decided to move from a temporary to a normal table. Maybe by adding a field 'user '.
  In such a scenario, you can find ways where the output is sorted not more properly.

  I can't find Google evidence.

  2. what happens if I order by as:

  select * from TMP_PAYMENT_ANNUITY
  ORDER BY ROWID;
  

  This approach maybe gives me the order of the rows as they are in the table?

  main problem is that you cannot test if it STILL works without order. But you will need to find not only one rare case that breaks it.

  * In a multiuser environment, the table could put a few lines where another session comes to delete certain lines. This could influence the agenda.
  * oracle could change something for the release of "like orders ' (I did they did already in the GROUP BY clause from 9i to 10g).

• How to insert into a GLOBAL TEMPORARY TABLE and get the data from it?

  The requrement is
  Split the string ENTRY point on the base and store it in a Collection. And the values of the collection will be stored in a global temporary table. Then, I'm updating some other table based on the data from the temporary table.
  
  There is in fact no error message. But there is no data in the temporary table and also no change in the update statement
  
  First of all, I'm creatiing a global temporary table only once outside the procedure.
  
  CREATE GLOBAL TEMPORARY table GLt (data_element number)
  
  
  create or replace procedure test_proc (p_in_string VARCHAR2) is
  i the number: = 0;
  number of POS: = 0;
  CLOB lv_str: = p_in_string;
  p_delim VARCHAR2 (1): = ', ';
  
  TYPE t_array IS TABLE OF VARCHAR2 (20) INDEX directory.
  t_array channels;
  
  BEGIN
  
  -cutting of string input and store in the strings (i) collection
  
  POS: = instr (lv_str, p_delim, 1, 1);
  WHILE (pos! = 0) LOOP
  i: = i + 1;
  Strings (i): = substr(lv_str,1,pos-1);
  lv_str: = substr (lv_str, pos + 1, length (lv_str));
  POS: = instr (lv_str, p_delim, 1, 1);
  IF pos = 0 THEN

  Remove the two execute immediate line. They are wrong.

  And then use the table in your code that you created at the beginning. The name is GLT.
  And delete the first commit. This validation would empty the temporary table of GLT.

  You get an error? Or it does not work as expected?

  Also, show how you call the procedure.
