• How to use the Type of Oracle Table values in the Select statement.

  Hello
  
  I get the initial set of values in the Table of Type Records of the Oracle and want to use the list of values in the Select statement.
  
  For example, try something like the following:
  
  TYPE t_record () IS RENDERING
  ID TABLEA.ID%type,
  NO TABLEA.NO%type
  
  );
  v_record t_record;
  T_table TYPE IS the v_record TABLE % TYPE;
  v_table t_table;
  
  -Code to fill the values of v_table here.
  
  SELECT ID, NO, COLLECT in BULK IN < some other table variabes here > FROM TABLEA
  WHERE ID IN (i) v_table USER.USER;

  Something like this:

  create or replace type t_record as  object (

• How to add an imaginary line in the result of the value of a SELECT statement.

  Hello all-
  
  I have requirment to add an imaginary line in the result set of a SELECT statement.
  
  For example lets say it is a pay table having the following columns:
  
  Number of Payment_id
  status varchar2 (10)
  number amount
  date of payment_date
  
  so here's the data: -.
  
  Payment_id status amount payment_date
  applied 1 100 12/07/2008
  2 Reversed 200 01 / 06/2009
  Applied 3 300 01 / 07/2009
  
  
  Here is my SQL
  
  Select * form payment where payment_date > = 01/01/2009
  
  The output will be
  
  2 Reversed 200 01 / 06/2009
  Applied 3 300 01 / 07/2009
  
  My desired output is less than
  
  2 Reversed 200 01 / 06/2009
  Applied 3 300 01 / 07/2009
  reversed-200 2, 01 / 06/2009-(Dummy Row)
  
  Third line here is the imaginary line that I add when the status is "reversed".
  
  I would be very grateful for any help on this...
  
  Thank you
  Gerard

  NB. You may need to mess around with the order if that is not in the order you want. You did not mention what the rules were for all orders expected, so I composed my own * {;-)

  Also, I added a (cust_id) identifier to differentiate different types of payments, as is usually the case. Remove unless it is not applicable to your case.

• Get multiple values in a select statement in a variable to a procedure

  Hello

  I'm trying to craete a procedure where the entry of the procedure will be a similar string "a, b, c, d" and output the values of a table that matches the value separated by commas of in sting.

  For this.

  create table test (varchar2 (10)) nm;

  Insert test values ('a');

  Insert test values ('b');

  Insert test values ('c');

  Insert test values (');

  Select * from test;

  NM

  ------

  one

  b

  c

  d

  Now I'm doing a procedure where the parameter will be the column values NM of TEST table in a string separated by commas like "a, b, c, d, x, l" there could be false values also.

  The procedure will return only the values that are adapted with column NM from the TEST table for this I created this procedure.

  create or replace procedure p_test (p_nm IN varchar2 / *, THE sys_refcursor p_out * /)

  is

  number of l_len;

  l_val varchar2 (10);

  l_val1 varchar2 (10);

  Start

  l_len: = length (p_nm);

  -dbms_output.put_line (l_len);

  Start

  because me in 1.l_len

  loop

  Select REGEXP_SUBSTR (p_nm, ' ([^,] *)(,|$)', 1, I, NULL, 1) in double l_val;

  -dbms_output.put_line (l_val);

  -Open p_out for

  Select * into l_val1 of test where nm = l_val;

  dbms_output.put_line (l_val1);

  output when l_len is null;

  end loop;

  exception

  When no_data_found then

  null;

  end;

  exception

  while others then

  dbms_output.put_line (' error reason :'||) SQLERRM |' :'|| error code SQLCODE);

  end;

  EXECUTE p_test ('a, b, c, d, q, w');

  OUTPUT-

  one

  b

  c

  d

  This procedure gives me out as I need, but I need to get this in a variable which should be OUT the parameter of this procedure will be called by the JAVA for our application.

  As I already tried to use the refcursor (see the commented part), but it gives me no output during a call there.

  Its a call to this procedure when I use the refcursor (removing comments).

  declare

  l_out sys_refcursor;

  l_val varchar2 (20);

  l_str varchar2 (20): = 'a, b, c, d;

  Start

  p_test (l_str, l_out);

  loop

  extract the l_out in l_val;

  dbms_output.put_line (l_val);

  dbms_output.put_line ('a');

  When the output l_out % notfound;

  end loop;

  end;

  So here I am stuck with that, how to get the result of multiple or I'm missing something here and if there is a better approach to this requirement as I come with that so I'm sharing it here.

  First of all, get rid of it WHEN OTHERS like William already noted. If you do not want to use the collections:

  SQL > create or replace
  function f_test () 2
  3 p_nm varchar2

  6 is
  v_result 7 varchar2 (4000);

  9. Select listagg (nm, ',') within the Group (nm control)
  10 in v_result
  11 test
  where the 12 «,» | p_nm | ',' like '%', | NM | ',%';
  13 return v_result;
  14 end;
  15.

  The function is created.

  SQL > start
  2 dbms_output.put_line (f_test ('a, b, c, d, x, w'));

• How to select several values with a select statement with other columns

  Hi all

  I have a small request related to the selection of values in a table.

  create table employees (eid, ename varchar2 (20));

  insert into employee values (1, 'Nik');

  insert into employee values (2, "Prashant");

  commit;

  
  Now, I have a small list of say A, b, C, I want to choose this list with all the lines as

  with test1 as)

  Check the eid, ename for employee

  )

  Select eid, ename, 'A' col1 in test1

  UNION ALL

  Select eid, ename, 'B' col1 in test1

  UNION ALL

  Select eid, ename, 'C' col1 in test1

  but the problem with that is that in production my employee table has millions of records and it scans the employee three times table (or the number of constant values)

  Is there another way to do this.

  Thank you

  Nik

  Here is an approach with the scanning of a single table test1

  Select t.eid, t.ename, c.col1

  t test1

  Cross join (select 'A' col1 of union double all the)

  Select 'B' of all the double union

  Select the double ' C') c

• Set the first value after the select statement

  Hello
  
  I have a problem here.
  
  After you run the statement select, it'll come to me:

  EXC
  NRD
  RDY
  
  
  
  My question: How can I set the first value instead of 'COM' in "EXC"?
  
  Thank you.

  Hello
  Where you use this instead:

  select *

  order by "id" desc
  

• can 'build' a select statement by using a control of IF-ELSE?

  I need to create a stored procedure that accepts as pararmeter account number and status. If the status is 'A' for approved, so I want to return all price records in my table of prices for this account number, otherwise if the status is 'R' for the dismissal, I want to read data from a price change of queue, which has also the error code and description. If the status is null, then I want to send prices of the assets of the PRICE table AND rejected him to the Chronogram of the queue of price:
  
  Can I do something like this in PL/SQL?
  

  If param_status = 'A' or param_status is null THEN
     SELECT ACCT_NO, PRICE, EFFECTIVE_DATE, null, null
     FROM ACCOUNT
     where ACCT_NO = param_acct_no
  
  Elsif param_status = 'R' or param_status is null THEN
  
  UNION
     SELECT ACCT_NO, PRICE, ENTRY_DATE, ERR_CD, ERR_DESCRIPTION
     from PRICE_CHANGE_QUE
     where ACCT_NO = param_acct_no
         and  STATUS = 'R';
  END IF;

  I ', m using Oracle 11.2, and I plan to return the results as a cursor must be used in a .NET application.
  
  I need display all prices of ASSETS, or any REJECTED price, according to it if the status is sent on or not.

  Hello

  If you want an application that does it all:

  select  ACCT_NO, PRICE, EFFECTIVE_DATE, null,   null
  from      ACCOUNT
  where     ACCT_NO     = PARAM_ACCT_NO
  and     'A'     = nvl (:PARAM_STATUS, 'A')
       --
      union
       --
  select     ACCT_NO, PRICE, ENTRY_DATE,     ERR_CD, ERR_DESCRIPTION
  from     PRICE_CHANGE_QUE
  where     ACCT_NO = param_acct_no
  and       STATUS      = 'R'
  and     'R'     = nvl (:PARAM_STATUS, 'R')
  ;
  

  SQL is sufficient for this purpose; you needn't PL/SQL.

  It will probably be more effective to your .NET application so check param_status is 'A', 'R' or NULL first, then branch to one of the 3 most effective query.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  If the problem involves (for example param_status) parameters that are not in any table, and then after a few differetn sets of parameters and the results you want from the same sample for each game data.
  Always tell what version of Oracle you are using.

• Return multiple values from a function in a SELECT statement

  I hope I've provided enough information here. If not, let me know what I'm missing.
  
  I create a view that will combine the information from several tables. Most are pretty simple, but there are a couple of columns in the view that I need to get by running a function within a package. Even if this is quite simple (I have a function named action_date in a package called rp, for example, that I can use to return the date that I need through SOME rp.action_date (sequence_number).
  
  Here is the question: I really need to return several bits of information of the same record (not only action_date, but also action_office, action_value, etc.)-a join of the tables will work not here, as I will explain below. I can, of course, perform a function separate for each statement, but this is obviously inefficient. Within the select statement of the view, however, I don't know how each of the values that I need to get back.
  
  For example, right now, I have:
  
  Table 1:
  sequence_number NUMBER (10),
  name varchar (30),
  ...
  
  Table2:
  Table1_seq NUMBER (10),
  action_seq NUMBER (10),
  action_date DATE,
  action_office VARCHAR (3),
  action_value VARCHAR (60),
  ...
  
  I can't just simply join Table1 and Table2 because I have to perform processing in order to determine the rows returned matching, I really need to select. If the package opens a cursor and treats each line until it finds the one I need.
  
  The following works but is ineffective since all calls to the package returns the columns of the same record. I don't know how to put all the values that I need in the SELECT statement.
  CREATE VIEW all_this_stuff AS
  SELECT sequence_number, name,
  RP.action_date (sequence_number) action_date,
  RP.action_office (sequence_number) action_office,
  RP.action_value (sequence_number) action_value
  FROM table1
  
  Is there a way to return multiple values in my SELECT statement or I'm going about this all wrong?
  
  Any suggestions?
  
  Thank you very much!

  Hello

  What you want is a Query of Top - N , what you can do using the ROW_NUMBER analytic function in a subquery, like this:

  WITH     got_rnum     AS
  (
       SELECT     action_seq, action_dt, action_office, action_type, action_value
       ,     ROW_NUMBER () OVER ( ORDER BY  action_date
                                 ,            action_seq
                           ,            action_serial
                         ) AS rnum
       FROM     table2
       WHERE     action_code     = 'AB'
       AND     action_office     LIKE 'E'     -- Is this right?
  )
  SELECT     action_seq, action_dt, action_office, action_type, action_value
  FROM     got_rnum
  WHERE     rnum     = 1
  ;
  

  As written, this returns a single line (at most).
  I suspect you'll actually get a rank for each group , where a group is defined by a value in a table in which you join.
  In this case, add a PARTITION BY clause to the ROW_NUMBER function.
  If post you a small example of data (CREATE TABLE and INSERT statements), I could show you exactly how.
  As I don't have your tables, I'll show you the use of the tables in the scott schema.
  This is a view containing data in the scott.dept table and also to scott.emp, but only for the highest employee in each Department (in other words, the employee whose oldest hire date). If there be a tie for the first hire date, while the candidate with the lowest empno is selected.

  CREATE OR REPLACE VIEW     senior_emp
  AS
  WITH     got_rnum     AS
  (
       SELECT     d.deptno
       ,     d.dname
       ,     e.empno
       ,     e.ename
       ,     e.hiredate
       ,     ROW_NUMBER () OVER ( PARTITION BY  d.deptno
                                 ORDER BY          e.hiredate
                           ,                e.empno
                         ) AS rnum
       FROM     scott.dept     d
       JOIN     scott.emp     e     ON     d.deptno     = e.deptno
  )
  SELECT     deptno
  ,     dname
  ,     empno
  ,     ename
  ,     hiredate
  FROM     got_rnum
  WHERE     rnum     = 1
  ;
  
  SELECT     *
  FROM     senior_emp
  ;
  

  Output:

  .    DEPTNO DNAME               EMPNO ENAME      HIREDATE

  Moreover, one of the conditions to the query you posted has been

  action_office     LIKE 'E'
  

  which equals

  action_office     = 'E'
  

  (AS is always equivalent to = if the string that follows AS does not contain the winning cards.)
  Did you mean say that or did you mean something like this:

  action_office     LIKE 'E%'
  

  Instead?

• Create a temporary table and insert using a select statement

  Hello
  
  I tried to create a temporary table and insert it by using the value in a select statement. Please see below the code

• How does a facility TestStand to parse a string to a TcpIp Read?

  L & G,

  I am interested by linking TestStand for a product of mine and I downloaded the eval and spin a typically TcpIp sequence as shown in the examples.  I'm trying to understand how to configure TestStand to parse the string coming back from my server too the success/failure and test results information present in the returned string.

  I look forward to your responses and thank you for your help.

  Craig Byrd

  L & G,

  I figured out how to create and use a local variable (string) as the chain of TCPWrite by simply changing the TCPWrite to the stage and set the the Results.Data value to use theLocals.TCP.

• Could not save the different string value to each element of the array

  I have a configuration of VI to read several channels Veristand project.  The entrance is a table 1 d of channels, (an element for each channel, I want to read).  The channels have different names, each of the elements in the chain must be different.  I am able to edit each item and run the VI, and it works fine.  However, if I save, close and reopen the VI, all elements show the same value (what happens to the value of the last element for which I defined a default value).  Is this behavior planned, or have I missed a configuration setting which would allow different string values?  Please notify.  Thank you.

  Make sure that you select the table and not only one item when you right click-> set by default on the front panel.

• comparing string values in the same table

  I have a table with ID (14 digit string values) starting with "A". Ex: A21849B1020792. There may be a different ID with the same substring 'B1020792' in the same table, example: A12349B1020792. If this happens, the ID of the last creation date of must be returned in the result. In other words, comparison is done on the same table. "In the example provided, say A12349B1020792 has the date of 1 January 2015 'and A21849B1020792 has date February 1, 2015", since A21849B1020792 has the most recent date, the result must contain only A21849B1020792.

  ID create_date

  A12349 B1020792 01/01/2015

  A12345B1234567 01/03/2015      

  A43567B1234567 01/04/2015      

  
  Here's the query I used:

  substr (a.id, 7) select sc, max (a.create_date) cd1

  of table a, table b

  where a.id! = b.id

  and substr (a.id, 7) = substr (b.id, 7)

  and a.id like 'A %' and b.id like 'A %' / * (I used a % because I am interested only IDs that begin with A) * /.

  and a.id ('A12349B1020792', 'A21849B1020792','A12345B1234567 ','A43567B1234567')

  Group of substr (a.id, 7);

  Result:

  ---------

  ---                    ------

  B1020792 02/01/2015

  B1234567 04/01/2015

  There is one thing that I'm not able to do with my request, that is, be able to get real IDs list and not list of substrings. If I added a.id column in the select clause and the group by clause, the query includes both by substr (a.id, 7) and a.id and as a result, the query returns four lines as below:

  substr (a.id, 7) select sc, max (a.create_date) cd1, a.id ID

  of table a, table b

  where a.id! = b.id

  and substr (a.id, 7) = substr (b.id, 7)

  and a.id like 'A %' and b.id like 'A %' / * (I used a % because I am interested only IDs that begin with A) * /.

  and a.id ('A12349B1020792', 'A21849B1020792','A12345B1234567 ','A43567B1234567')

  Group by substr (a.id, 7), a.id.

  Result:

  ---------

  sc                    cd1                      ID

  ---                    ------                   ---------

  01/01/2015 A12349B1020792 B1020792

  B1234567 01/04/2015 A43567B1234567

  
  

  My goal is to retrieve a list of all the unique identifiers that have the later dates.

  If it makes sense to treat the first 6 characters of the ID separately from the rest of the id in this problem, maybe it makes sense to store those two parts of the id in two different columns.  Relational databases work best when each column of each row contains 1 single piece of data (at most).  It is so fundamental to the design of table that he called the first normal form.

  Given that the two parts are stored in column 1, so you can something like this Request Top - N:

  WITH got_r_num AS

  (

  SELECT r.id

  r.create_date AS cd1

  , RANK () OVER (PARTITION OF SUBSTR (r.id, 7))

  ORDER BY r.create_date DESC

  ) AS r_num

  FROM table_x g - g for data values

  JOIN table_x r - r for related values

  ON SUBSTR (r.id, 7) = SUBSTR (g.id, 7)

  WHERE g.id IN ('A12349B1020792'

  , "A21849B1020792".

  , "A12345B1234567".

  , "A43567B1234567".

  )

  - AND g.id LIKE 'A %' - if necessary.   The above condition ensures already g.id start with "A".

  AND r.id LIKE 'a % '.

  )

  SELECT id, create_date

  OF got_r_num

  WHERE r_num = 1

  ;

  If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test this.

• using the function - how to use the values of the input variables on the table select statement names

  Hello community, I have a problem when creating a function. The purpose of this function is to check the table of weather gave yesterday or not. We must check this on different tables on different sachems. We are creating a function with input variables.

  END;

  When creating, I got error: [error] ORA-00942 (44:19): PL/SQL: ORA-00942: table or view does not exist

  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).
