Number of unique values in 7 columns

• Column sum based on a single value of another column

  Hi all

  I've searched and searched, but just can't find if this is even possible, let alone how to do it.  What I'm trying to do, it's the sum of a column.  However, only summarize the results of this column if a specific value of another column is present.  So, for example, the following is a sample database entry:

  Rate of pay hours

  2.3                                  $14.00

  1.2                                  $14.00

  2.4                                  $12.50

  0.75                                $12.50

  So for that, I want the sum of hours worked column but only the sum of hours worked if the wage rate is $14.00 and $ 12.50.  Because these numbers are generated in a database (with the various people who enter multiple rates of pay), I won't be able to set the where statement to have a specific amount (since I don't know the specific amount each registrant), the amount must be a variable in the where the statement.  With MySQLI, I know not how to make the sum of hours worked, but I do not know how the sum of hours worked if and only if the line corresponds to the unique value in the rate column.

  Then have it automatically loop through and total hours worked for other unique values in the column salary rate.  Finally, out all unique values in the column rate in variables so that I can do the following for each game:

  $total1 = $total_hours1 * $wage_rate1
  $total2 = $total_hours2 * $wage_rate2
  $overall_total = $total1 + $total2
  

  where $wage_rate1 = $14.00 and $total_hours1 = 2.3 + 1.2: etc.

  Is it still possible?  If so, how?  If possible, can someone please let me know a good reference so I can learn how to be the best way to implement?

  Thank you

  So with that, I get the correct $final_total printed, but I still get the error, 'notice: Undefined variable: final_total. Why is it not defined, but prints the total exact? How to remove the error?

  You get this notice is because you use the assignment combined, operator that is normally used to add a value to a variable and assign the new value to it.

  $final_total += $total;

  is a shortcut for this:

  $final_total = $final_total + $total;

  The undefined $final_total is on the right side of the assignment operator. The first time through the loop, you add $total to a non-existent value. Because of the type of PHP juggling, this becomes:

  $final_total = 0 + $total;

  The next time the loop runs, $final_total has a value, so that you get the view variable not defined only once.

  To avoid advice, initialize $final_total to zero before the start of the loop.

  $final_total = 0;

  While ($row = {$sql-> fetch_array())}

• Number of unique key in a table column

  Hi all...
  
  
  Please help me with this problem. Looking for the number of threads, but could not understand how do.
  
  
  I have a master form / retail users (main table) and responsibilities (detail table).
  The problem is with the table Details (responsibilities), the detail is "" "FORM TABULAR" ".
  A user can have the following responsibilities RESP1, RESP2, RESP3, RESP4 (it's a '' select list' ")
  
  
  When the administrator creates users, they will strike "" Add line"," once they choose a responsibility of the selection list.
  When they hit add line once again, "'chosen responsibility should display in the selection list.
  
  
  EX: when they select RESP "RESP1' in the first row, if they hit add line once again,"RESP1"does not present it as an option for users to select.
  
  
  EX: If the user already has an RESP "" RESP3"" in the database, "'' RESP3" ' should not display if they try to add another RESP.
  
  Each select list should display different values depend on the values they have chosen so far *.
  
  -> we can put constaint unique key on this column or put validation on this page, but I'm looking for the implementation
  
  
  Please check the following application example:

  There is no way to declaratively in the Apex to do this.

  In version 4.x:
  1. There is no declarative way to dynamically filter a list of values in a tabular presentation. For each line, the LOV is actually pre-built on a hidden row zero when the page first appears.
  2. to do this, you will need to come up with a process, possibly including AJAX, to fill an array of values to the selection list, delete the values in the table if they have been selected on the other lines of the page and then re - fill the selection on the new list online.

  In version 3.x:
  1 lines are stored in the database every time that you add a row (actually the page saves and repainted with a new line). You can set your LOV SQL to return the values valid less those already stored in the database that the user adds lines.
  2. However, that won't necessarily work 100% if you look at a page with several lines already on it and want to update the existing lines and you need in any case a sort of validation or a unique constraint.

  It is not impossible, but it's very very labor intensive and maintainability is more difficult if another developer a year or two down the road to inherit this page you.

  I'd really like to tell your business analyst or key functional end users what they ask for is not supported by Apex first review (and to tell you the truth, it is indeed non-supported, so you are not lying down or fake apology) and they consider like allowing more traditional validation via a unique constraint and page validation.

  No it's not got the foreign keys and this isn't the primary key...

  In this case, you should be able to MERGE, also:

    2                   ,emp_id number not null unique);
  
  Table created.

• Dynamic list of unique values

  I	II
  A	A
  A	B
  B	C
  B
  C
  C

  I wish I had a way to calculate the values in the column II of the values in the column I. I has many duplicates, and two column he only unique values. What is the best way to achieve this?

  Here's a method:

  

  Column B, the column in the Index, can be hidden.

  Formulas:

  in B2 and filled until the end of the column B:

  IF (COUNTIF(A$2:A2,A2) = 1, MAX(B$1:B1) + 1"," ")

  It counts the number of times the value of 'this line' column that has occurred in cells A2 to 'this line '. If the number is 1, the formula returns an index number one greater than the largest number already in the column in the index.

  In C2 and filled until the end of the column C:

  IF (LINE (−1) > MAX (B),"", LOOKUP (ROW () −1, B, A) ")

  The first part of this is a switch that prevents the SEARCH part to act if all the distinct values have been retrieved. If thye have not, SEARCH returns the value to the column of the row whose column B contains a number one at least the number of line of 'the line '.

  Kind regards

• insertion of unique values as well as the value of the sequence

  Hello gurus,

  I need to copy values from table A to table B as well as the value of the sequence.

  Please find the scripts below.

  -Table A and insert

  create a (varchar2 (40) of ename, space job_id varchar2 (40));

  insert into a values ('Suri', 'THIS');

  insert into a values ('Suri', 'THIS');

  insert into a values ('ABC', 'Admin');

  -Creation of table B

  create table B (number empno, ename varchar2 (40), job_id varchar2 (40));

  -sequence to fill data in table B empno

  create sequences b_empno_seq.

  Requirement is that we need fill out the unique values in table A in table B as well as the sequence (for the empno column) value

  Please find below the insert and update statements I tried below.

  Please let me know if we have a better approach

  INSERT INTO B (ename, job_id)

  SELECT DISTINCT ename, job_id

  A.;

  UPDATE b b1

  SET empno = b_empno_seq. NEXTVAL

  WHERE ename in (SELECT ename b B2 WHERE b2.ename = b1.ename);

• unique index on two columns

  Hi all
  I want a unique index on two columns, but when I try this it will show me

    1  CREATE UNIQUE INDEX sale_order_no
    2*   ON sale_order (sale_order_no, season_year)
  SQL> /

  Plaese Guide
  Thanks and greetings

  You would this behavior if SALE_ORDER_NO has NULL values. If it contains NULL values, a unique single-column index will succeed but an index unique multi-column will fail when it finds duplicates in SEASON_YEAR.

• SQL question - aggregate rows based on the value of the columns

  Hi all

  DBA_EXTENTS reports on the number of starting point of measurement (column BLOCK_ID) and the size of the scale in the Oracle (BLOCKS column) blocks.

  I'm trying to combine the lines of the segments of same as if their associated extensions are adjacent.

  For example, assume that the data in the view are as follows:

  Nom_segment	Block_id	BLOCKS
  EMP	10	8
  EMP	18	8
  DEPARTMENTS	26	16
  DEPARTMENTS	42	8
  EMP

  5016EMP668

  And I want to do a set of results that looks like this:

  Nom_segment	Block_id	BLOCKS
  EMP	10	16
  DEPARTMENTS	26	24
  EMP	50	16

  I thought to use an analytical query, but I couldn't find something that meets this requirement.

  Can you please help?

  Hello

  Here's a way to do that using the analytical SUM function:

  WITH got_grp AS

  (

  SELECT nom_segment, block_id, blocks

  , block_id - SUM (blocks) over (PARTITION BY nom_segment

  ORDER BY block_id

  ) AS the grp

  FROM the data

  )

  SELECT nom_segment

  MIN (block_id) AS grp_block_id

  SUM (blocks) AS grp_blocks

  OF got_grp

  GROUP BY nom_segment, grp

  ORDER BY grp_block_id

  Thanks Frank,.

  If you would care to post CREATE TABLE and INSERT to your sample data and the version of your database, then I could show you exactly.

  The Oracle version is 11.2.0.4

  This is the CREATE TABLE and INSERT statements for the sample data:

  CREATE THE TABLE DATA (NOM_SEGMENT VARCHAR2 (20), BLOCK_ID NUMBER, NUMBER OF BLOCKS);

  INSERT IN DATA VALUES ("EMP", 10, 8);

  INSERT IN DATA VALUES ("EMP", 18: 8);

  INSERT IN DATA VALUES ("DEPARTMENTS", 28, 16);

  INSERT IN DATA VALUES ("DEPARTMENTS", 42, 8);

  INSERT IN DATA VALUES ("EMP", 50, 8);

  INSERT IN DATA VALUES ("EMP", 66, 8);

  is not the same as the data in your first post and the results are not the same, either.

  The fixed difference technique involves lines don't overlap.  In the sample data in response #3, 'DEPARTMENTS' lines overlap, i.e. blocks 42 and 43 belong to two segments.

  Sorry, I can't understand what you want.

  If you want the production order 1, then put a literal 1 for the value of this column:

  INSERT INTO Bill (ordid, description, prodid, actualprice, qty, itemtot)

  VALUES (& ordid, ' & description', & prodid, & actualprice, 1, & itemtot)

  ;

  or, if that value is used elsewhere in your script, set a variable substitution:

  DEFINE Qty = 1

  INSERT INTO Bill (ordid, description, prodid, actualprice, qty, itemtot)

  VALUES (& ordid, ' & description', & prodid, & actualprice, & qty, & itemtot)

  ;

  I hope that answers your question.

  If this isn't the case, post an example, such as:

  "If the user types... then the created line must contain... but if the user types... then the new line should be... »

  Simplify the question.  Do you really need 6 columns to show what you don't understand?  Why not just 2 or 3 columns?
