  How to use the values of the input variables on the table select statement names?

  Hello

  Here's a way you can use dynamic SQL statements for this task:

  CREATE OR REPLACE FUNCTION IS_YDAYDATA_TO_TABLE

  (

  in_schema IN VARCHAR2,

  in_tablename IN VARCHAR2,

  in_datefield IN VARCHAR2,

  in_first_date DATE DEFAULT SYSDATE - 1,.

  in_last_date DATE by DEFAULT NULL

  )

  RETURNS INTEGER

  AS

  -IS_YDAYDATA_TO_TABLE returns 1 if in_schema.in_tablename.in_datefield

  -contains all the dates in the in_first_date of the range through included in_last_date

  - and it returns 0 if there is no such lines.

  -If in_last_date is omitted, the search only the data on in_first_date.

  -If in_first_date is omitted, it defaults to yesterday.

  -Time parts of the in_first_date and in_last_date are ignored.

  -Declaring variables

  sql_txt VARCHAR2 (1000);

  v_is_true INTEGER.

  BEGIN

  sql_txt: = 'SELECT COUNT (*).

  || 'FROM ' | in_schema | '.' || in_tablename

  || 'WHERE ' | in_datefield | ' > =: d1'

  || «AND» | in_datefield | '< >

  || 'AND ROWNUM = 1';

  dbms_output.put_line (sql_txt |) '= sql_txt in IS_YDAYDATA_TO_TABLE");  -For debugging

  Sql_txt EXECUTE IMMEDIATE

  IN v_is_true

  With the HELP of TRUNC (in_first_date) - d1

  TRUNC (NVL (in_last_date

  in_first_date

  )

  ) + 1                -- d2

  ;

  RETURN v_is_true;

  END is_ydaydata_to_table;

  /

  DISPLAY ERRORS

  If you must use dynamic SQL statements, put all the SQL statement in a single string variable, such as sql_txt in the example above.  In this way, you can easily see exactly what will be executed.  Comment out the call to dbms_output under test is completed.

  Try to write functions that will address not only the question that you have now, but similar questions that you may have in the future.  For example, now that interest you only to the verification of the data of yesterday, but later, you might want to check another day or range of days.  The above function combines the convenience of a function simple (looks like yesterday data if you don't tell him otherwise) with the power of a more complex function (you can use the same function to check any day or range of days).

  You cannot reference variables as you did and get the value of the variable. Use pretty collection.

  set serveroutput on size 2000
  declare
    type      number_table is table of number;
    numbers   number_table := number_table(10, 20, 30, 40, 50);

      dbms_output.put_line(i || '->' || numbers(i));

• Using variables such as table names. Ideas for alternative designs

  Hello

  I am the design of an application that uses synonyms to pull information from the 'client' DBs via links from DB. Synonyms are created with a DB_ID in name (example: CUSTOMER_100, CUSTOMER_200... where the 100 and 200 are DB IDs of 2 separate DBs customer.)

  I have a procedure that selects data in the synonym based on what DB_ID is passed to the procedure. I want to be able to perform this procedure for any entered DB_ID. I know now I can't use variable for the table names names and using EXECUTE IMMEDIATE does not seem suitable for what I'm trying to do.

  Does anyone have suggestions or re-design options, I could use to achieve this generic procedure which will select a certain synonym based on the information of DB input parameters? Thank you.

  Your question seems to relate to Oracle Forms, which has its own forum of OTN.

  But as it comes to PL/SQL I will make a comment... Unfortunately this comment is that in reading your post, I don't know what you're asking.

  You wrote: "I need to know how can I give the values of these variables if I use the variable in my statement.

  What variable? Why don't you use a duty with: = as you obviously already know how to do?

  An example would be very useful.

  PS: Always display product names and version numbers.

• How to control the value of a variable that is shared at the beginning of the vi

  Hi all

  In short: How can I make sure the values of the variables shared at the start of a vi?

  I have two vi.

  One is a main vi where did I order a shared Boolean variable "run DAQ".

  The other is a vi with a while loop that "polls" for the shared variable "Execute DAQ", which is connected to a box Structure. If the case is false, it does nothing, if it is true is short some simple IO DAQ within a while loop.

  To be sure that at the beginning of the vi the variable 'Execute DAQ' shared value false (no matter what 'State' the shared variable was left in front of the vi began) I write a Boolean constant to this shared variable 'Execute DAQ' out of hand while loop.

  Now my question: how is it possible that the case structure can enter into the 'True' State, even when main vi is not executed and there is therefore no way of the shared variable can be written in. I know that shared variables are stored in memory, but that's why I write it to false at the beginning of the vi.

  Even when I read the first shared variable before you change it with a constant False the second instance of the shared variable that is wired to the case structure bed to True.
  It seems to me that the shared variables do not follow the 'right' of the dependence of LabView and are updated outside the normal flow of the vi.

  Thanks for your time and advise on this.

  Someone knows another way around this?

  Yes.  Do not use them.

  If you not post on a network, use a normal Global Variable or use a queue, the user event, stating to send commands indicating loops for updating their values.

  If on a network, then I recommend the network stream to send commands/data back with updates.  I used shared variables, more I hate them.

• How to use 'Extract values' transformation?

  Hello

  I'm new to Disqualification. I have the following requirement - source system sends me Nom_tiers + address details. I need to check in the oracle database and if there is a match then return the ID and details of entry. I use verification audit of research processes to check if the data is present in the database. If the data is present, then, I need to send the code. I use to extract the ID of transformation 'extract values '. I can't set the reference for this data. Can provide an example how to use the same.

  Just use Lookup and return.

  However, it seems that you really should use a matching process.

  Is another way simple, other than my approach?

  You should use point demand for it and an application process to fill
