• compare the data and the output data that do not exist

  Hello
  I've written a procedure to insert data into a table 3 where I compare the data between two tables, if it matches it insert in the table test_a Joanie. If the exists not or other tables i.e. test_code and test_type it should output this data, where there is no. my code works for a single table, which is test_code. It's not DBMS display a line that is not in the table test_type. could just tell my why? Assume that if test_code a line which is only not in test_type it should out saying this line of incompatibilities with test_type and vice versa.

  Thank you

  You must use a FULL OUTER JOIN instead an OUTER JOIN for this.

  Just curious, why do you need to use dbms_output instead to execute the SQL query with additional conditions (if part of your procedure)?. You can use two times, one to insert those that match and one for the selection of others who do not match.

  Kind regards.

• No need to advise - compare the date in *.sql with sysdate.

  Hi guys,.
  
  Need some help here.
  
  Someone has a script that will compare the date specified with the current sysdate. If previously, he will order that SQL * PLUS to leave immediately.
  The audit will be essentially in a script *.Sql. Whenever we run the script, @c:\script.sql, it will be first of all to compare the dates and decide whether to proceed with the rest of the codes (dml) below the date checker in the same script.sql
  
  Thank you

  I would like to combine the solutions of bencol and alberto:

  whenever sqlerror exit
  
  DECLARE
     v_date   DATE := TO_DATE('', 'YYYYMMDD');
  BEGIN
     IF v_date >= TRUNC(SYSDATE) -- or perhaps:  v_date>= sysdate
     THEN
       null;
     ELSE
       raise_application_error(-20000,'Date is before SYSDATE!');
     END IF;
  END;
  /
  
  whenever sqlerror continue
  
  -- rest of your script
  ...

• How do you compare the data collected continuously?

  So, I'm stuck on the basic architecture, therefore, hoping that you can push took me.

  What I have is a VI that measures the tensions permanently, then, I have a flow of power from DAQ hardware data points.  What I WANT is to act on the data points of tension, only, which are larger than the previous points.  For example, I want to act on the first data point, since it will be the most important, since there is nothing to compare to, then I want to compare the points of data subsequent to the first, until there is a greater than the first data point.  Then, I want to compare tensions the NEW value more and so on, etc. and act only on the NEW larger value.

  Consider this list of data points and corresponding outcomes:

  2 LAW

  4 LAW

  3. DO NOTHING

  3. DO NOTHING

  4-DO NOTHING

  5 LAW

  4-DO NOTHING

  5-DO NOTHING

  4-DO NOTHING

  3. DO NOTHING

  6 LAW

  I've been watch combinations of them for WHILE loops and shift registers and the tables, but the table would get so huge so fast and the MIN/MAX value of the TABLE palette function would get pretty slow and I don't need to evaluate all previous data.  I just need to be able to identify the highest value and then compare it to the following values until there is a NEW larger value.  It's a bit like how the warriors would fight several opponents until they lost and then, there's a new champion, and all subsequent warriors are compared to the new champion and so on and so forth.

  You have any suggestions on how to achieve this?  I'm puzzled.

  Thank you

  Dave

  Yes, either case will work, I put it in the structure case just to show that you need to put in there if you want to use.

• By comparing the Dates in a group of data (different lines)

  I have a requirement where I have to compare dates in a dataset for each employee.  The data looks like this:

  WITH test_data AS

  (SELECT the '1' AS pk, '5900' AS emp_id, '5' AS rec_id, to_date('01-JAN-2014') AS rec_date FROM dual

  UNION ALL

  SELECT '2', '5900', '5', to_date('01-FEB-2014') FROM dual

  UNION ALL

  SELECT '3', '5900', '5', to_date('01-MAR-2014') FROM dual

  UNION ALL

  SELECT '4', '5900', '5', to_date('01-JAN-2014') FROM dual

  UNION ALL

  SELECT '5', '5900', '6', to_date('06-JAN-2014') FROM dual

  UNION ALL

  SELECT '6', '5900', '6', NULL FROM dual

  UNION ALL

  SELECT '7', '5900', '6', to_date('01-JUL-2014') FROM dual

  UNION ALL

  SELECT '8', '5900', '7', to_date('29-JAN-2014') FROM dual

  UNION ALL

  SELECT '9', '5900', '7', to_date('29-SEP-2014') FROM dual

  UNION ALL

  SELECT '10', '5900', '7', to_date('01-OCT-2014') FROM dual

  UNION ALL

  SELECT '11', '8595', '5', to_date('01-SEP-2014') FROM dual

  UNION ALL

  SELECT '12', '8595', '6', to_date('05-SEP-2014') FROM dual

  UNION ALL

  SELECT '13', '8595', '7', to_date('30-SEP-2014') FROM dual

  UNION ALL

  SELECT '14', '8595', '7', NULL FROM dual

  )

  REC_ID column is composed of 3 different types of records, which must satisfy this requirement:

  REC_ID 5 acts as point of departure, and REC_ID 6 must have a REC_DATE within 7 days of REC_ID 5 REC_ID 7 must have a REC_DATE within 30 days of REC_ID 6.

  • If the requirements are any record in REC_ID 5 acts like zero day or the starting point;
  • Any record in REC_ID 6 must be within 7 days of the date of REC_ID 5;
  • Any record in REC_ID 7 must be within 30 days from 6 REC_ID.

  My results:

  Expected results - satisfactory records

  EMP_ID

  DATE_1

  DATE_2

  DATE_3

  5900

  1 January 14

  6 January 14

  29 January 14

  8595

  1 sep-14

  5 sep-14

  30 sep-14

  I don't know how to compare dates in a dataset that are on different lines.  I thought using self-joins, query using the window as rank (), factoring functions, but I'm stuck pretty quickly.

  I appreciate all help.  Thank you!

  WOW odie_63: it would be a blessing if I was... but unfortunately, I'm on 10 gr 2.  That would have been great!

  Frank Kulash:

  I'm stuck (mentally) to the fact that there is an amount without discernment of records in the base table for each type of REC_ID.

  Some employees have 5 folders for REC_ID, 10 REC_ID 6 and 7 for REC_ID 7, which leaves me confused in how many self-joins I should do, or if it is at all possible.  I did a lot of arithmetic of dates with the data on the same line and certain ranks () functions for data residing on different lines, but this 1 seems to confuse me...

  I ran 1 self-join as below to see what it looks like and it confused me even more because I know the timestamp of the arithmetic in where clause still will not produce data as I want...  I am now trying another way...

  SELECT td2.rec_id,

  TD2.emp_id,

  TD2.rec_date

  Of

  test_data2 td2

  LEFT JOIN test_data td1 ON td1.emp_id = td2.emp_id

  
  

  It's a good start.

  You want an inner join, however, not an outer join, not you?  Outer join means "include td2 lines if they have data in the corresponding TD1".  If I understand the question, you are only interested in cases where it is matching data.

  Here's a way to do it:

  WITH joined_data AS

  (

  SELECT d5.emp_id

  d5.rec_date LIKE date_1

  d6.rec_date AS date_2

  d7.rec_date AS date_3

  ROW_NUMBER () OVER (PARTITION BY d5.emp_id

  ORDER BY d5.rec_date

  d6.rec_date

  d7.rec_date

  ) AS r_num

  OF test_data d5

  JOIN test_data d6 ON d6.emp_id = d5.emp_id

  AND d6.rec_date > = d5.rec_date

  AND d6.rec_date<= d5.rec_date="" +="">

  JOIN test_data d7 ON d7.emp_id = d6.emp_id

  AND d7.rec_date > = d6.rec_date

  AND d7.rec_date<= d6.rec_date="" +="">

  WHERE d5.rec_id = '5'

  AND d6.rec_id = "6"

  AND d7.rec_id = "7"

  )

  SELECT emp_id, date_1, date_2, date_3

  OF joined_data

  WHERE r_num = 1

  ;

  The subquery joined_data find all combinations of rows that meet the criteria.  We want to only 1 line by emp_id, so I used ROW_NUMBER assign unique r_nums (starting at 1) to all lines with the same emp_id and then, in the main query, rejected all but the 1st row.

  Knapen had a good idea, but it won't work for all cases.  There may be situations where the only combination of rows that meet the criteria does not use the MIN or MAX of dates of one (or several).

• Why I need to_char allows to compare the date?

  Hi guys:
  
  I have a question that seem silly, but I couldn't know.
  
  I have a simple query on Oracle 11 G R2 and I use SQL developer 3.1.07, the schema and the data has been migrated from a SQL Server:
  

  select *
  from vernote 
  where whendate='09-JUL-12';

  It returns empty results. However, tuples are in the table. When I try this:
  

  select *
  from vernote 
  where to_char(whendate)='09-JUL-12';

  He returned 677 lines. the whendate data type is date. but when I try another table in the same pattern:

  select *
  from invoices
  where transpostdate='09-JUL-12';

  It returns tuples, and I don't have to use the function to_char. transpostdate is also a date. Could someone tell me why the two columns: whendate, transpostdate both are of type date, but I have to use to_char to compare, the other does not?
  
  Thanks in advance!

  What kind of data are WHENDATE & TRANSPOSTDATE?

  If they are the data type DATE, then they contain data too part TIME.
  NEVER rely on the implicit data type conversion.
  July 9, 12 ' is STRING; not a DATE

  When TRUNC (transpostdate) = TO_DATE('09-JUL-2012','DD-MON-YYYY');

• query by default two tables for block

  Hello
  How can I make defaulet query block of two tables?
  I know it's default_query in set_block_property, but there is no clause only 'where' and I put clause of two tables. Is a solution?
  
  concerning

  You can use a block of Clause From database. This allows you to base a block on a complex query without having to create a view in the database. Here are the steps:
  

  
  
  1. Manually create a data block
     
  2. Create an item in the block for each column returned by the query - make sure that the data type is correct.
     
  3. In the block properties, set the following properties:
     
     
     
     • Query data Source type = F R O M Clause query
       
     • Data Source Name = your request
       
     • Mode key = U p d a t a b l e
       
     
     
  
  Note: If your query uses summary calculations, make sure you alias the result and ensure that matches alias name of the item in the data of block. It should also be noted that the blocks based on a F r o m query Clause are read-only. If you need be able to update the underlying tables, you can use transactional triggers or the block of data based on a procedure.

  For a complete list of this process - Discover My Oracle Support Document ID: * 69884.1 - how to use F rom query Clause in forms *.

• want to compare the data in excel with real-time signal

  Hello

  my request is to check the PCB pins of I/o... Firstly I have signal corresponding to each pin in GOOD PCB board and the output of each needle is saved in excel using scripture to the spreadsheet... then the database be act as master for more tips of PCB...

  If I want to check the other pcb edge means that the same signals should be send on the pin of each Member of the PCB... received out of the Council should check with the data already stored in the database if this is the way to match status LED should illuminate otherwise is not to shine...

  pls help me finish this application... I have attached model vi with poster and Excel in too...

  I hate to say it, but you don't have really any type of application there.  It is quite difficult to help you complete when you barely started.  An express VI couple in a sequence structure do not apply.

  What you need to do is sit down and write a design specification.  What are your entries for this application? What are your results?  What do you think the UI to look like?  What steps do you need to do to go from A to B?  Chart out.

• Calculated in point by comparing the Dates in IR

  Someone at - he was able to use a component calculated in IR to compare a date and post something else
  example of
  
  If (date > 1 January 2009 ') {1} else {2}
  
  I can not get to post whatever it is as 1 Although I graduate to that date dates in the field that I use to compare. Am I missing something, it seems like it should work, but it doesn't
  
  Any help would be appreciated.
  
  Thank you!!

  What is source and data type of the area date ?

  If it's a Date from the database then you compare a Date into a string. You need to convert one of them to the data of the other type

  Try

  If (date > ToDate (January 1, 2009 "")) {1} else {2}

• By comparing the data in the pass of 2 tables - with a calculation

  There are 20 records in 2 different tables (A and B). Records relate to periods between Jan 07 and 09 March. There is a logic that says that all records of 15 who are understood between Jan 07 and 08 Dec; their amount must be changed in Table B. While the amount for the rest 5 records that fall between Jan 09 and March 09 would remain the same. The formulas to be applied in the first 15 recordings is "amount/.50*0.125" and this result should take into account in the new table in the amount column.
  
  
  Now the task to ensure that the calculation that happened correctly in table A, for these 15 records that fall between January 2007 and December 2008 in Table B, and that the amount is the same for the records for the period after January 2009. I will conduct trials only that the new amount after the calculation of business logic is reflected in the new column of Table B.
  
  This, to a sql statement.
  
  Thank you

  you might want to try this pseudo-code

  update [2nd table]
     set amount = (select t.amount / .50 * 0.125
                     from (select id, rownum rn, amount
                             from [1st table]
                            where period_date between '01-JAN-07' and '31-MAR-09'
                           order by id) t
                   where  t.rn <= 15
                     and  t.id = [2nd table].id)
   where id in (select t.id
                  from (select id, rownum rn, amount
                          from [1st table]
                        where period_date between '01-JAN-07' and '31-MAR-09'
                        order by id) t
                 where  t.rn <= 15)
  

  It's even better if you can post the actual tables, columns and a few examples of data
