• More than 1 SQL query with checkbox and error invalid number report

  Hi all

  I have two SQL query reports that each has an apex_item.checkbox and two processes for each report.  A report/process works very well.  It gives me an error of invalid number.

  In addition, another query SQL (editable report) gives me the following error when using the Multi line process, delete.

  	ORA-06502: PL/SQL: digital or value error: character number conversion error ORA-06502: PL/SQL: digital or value error: character number conversion error
  Ok

  When I got a report from SQL query (with box and a process) and the query SQL (editable report) everything worked.  It stopped working when I added another SQL query report (with box and a process).

  A SQL query has the following in my query: apex_item.checkbox(3,email_id,'UNCHECKED') ""

  The other SQL query has the following: apex_item.checkbox(2,b.file_id,'UNCHECKED') ""

  Any help will be greatly appreciated,

• Use the DECODE and RIGHTEOUS in the sql query

  Friends...

  Could someone help with DECODE and sql RIGHT or similar function?

  I'm doing below in the SQL query

  1. DECODE any process with s.process = 1234 to replace with JAVA
  2. RIGHT: Removes all characters after ' @' sign

  SQL query:

  SELECT s.osuser, s.machine, DECODE(s.process, '1234', 'JAVA', right(s.process,charindex('@',s.process)-1)) s.process FROM v$session; 

  for example

  EXAMPLES of data

  User, machine, process

  John, mac1, 1234

  Mike, mac2, 567@mac2

• SQL query generated by insertion/update of data vi?

  Hello!

  I'm new to LabView, now rated as my company's management plans to buy licenses for several developers. I'm now playing with the database connectivity toolkit and try to insert/updated updated data sets. Everything is good with simple tables, but when I try to execute relatively complex queries are often mistakes LabView diagnosed everything as "syntax error in Update statement" or something like that with no specific details.

  Is it possible to read the actual SQL queries generated by these vi or is there a (preferably free) tool to monitor all SQL queries called by my LabView program?

  Here is the link I promised last night. It includes a review of the issues with the CSD and why it is not necessary. There is also a link with some drivers that allow you to do what you need to do and are free - and a brief tutorial on the access to databases.

• Clarification of the SQL query in 2 day + Guide APEX

  I worked through the Oracle Database Express Edition 2 day + Application Express Developer's Guide, and try to decipher the SQL query in Chapter 4 (building your app).

  The code is:

  SELECT d.DEPARTMENT_ID,

  d.DEPARTMENT_NAME,

  (select count (*) from oehr_employees where department_id = d.department_id)

  "Number of employees", he said.

  substr (e.first_name, 1, 1) |'. ' || Select 'Name Manager',

  c.COUNTRY_NAME 'place '.

  OEHR_DEPARTMENTS d,

  E OEHR_EMPLOYEES

  OEHR_LOCATIONS l,

  C OEHR_COUNTRIES

  WHERE d.LOCATION_ID = l.LOCATION_ID

  AND l.COUNTRY_ID = c.COUNTRY_ID

  AND e.department_id = d.DEPARTMENT_ID

  AND d.manager_id = e.employee_id

  AND instr (superior (d.department_name), superior (nvl (:P2_REPORT_SEARCH,d.department_name))) > 0)

  I don't know exactly what is happening in the last line. I think I understand what the different functions but I'm not clear on the use of the: P2_REPORT_SEARCH string.

  What does this string? This code simply checking that d.department_name isn't NA?

  I have SQL experience but am not very familiar with the Oracle PL/SQL implementation. Can someone please give me a brief breakdown that check is doing in the context of the overall query? The application seems to work even if the conditional statement is not included.

  Thank you.

  Thanks for the reply. I apologize if the information I added was incomplete. The code came from the day 2 + Application Express (version 4.2) Developer Guide.

  In the section 'your own Application of 4 Buuilding' https://docs.oracle.com/cd/E37097_01/doc.42/e35122/build_app.htm#TDPAX04000 , they describe the creation of a report

  page that includes the "manager_id" and 'location_id '. The SQL query, I pasted above extracted from the data in other tables to substitute the real 'name of the Manager' and 'rent '.

  for the corresponding ID values. It makes sense, and the part of the SQL query that explicitly doing this makes sense.

  However, given that the document is a guide for the development of the APEX, I guess the command:

  AND instr (upper (d.department_name), upper (nvl (:P2_REPORT_SEARCH,d.department_name))) > 0

  done something valuable, and I do not recognize what is exactly the value.

  From a practical point of view why would I need to include this conditional statement?  Which only added to the application?

  Looking at the guide in question, it is clear that the

  AND instr(upper(d.department_name),upper(nvl(:P2_REPORT_SEARCH,d.department_name)))>0
  

  the line is completely unnecessary in the context of this tutorial, and it can be removed. The search in the tutorial app page is implemented by using a report filter interactive rather than a P2_REPORT_SEARCH element, which does not seem to exist at all. (It's a quirk of the APEX that bind variable references to non-existent items are replaced with NULL silently rather than exceptions). I thought that perhaps it would be legacy code a version of the tutorial prior to the introduction of interactive reports at the APEX 3.1, but I can't find explicit instructions to create such an element of filter in the 3.0 tutorial. I guess it must have been automatically generated by the application wizard when you create a standard report page.

  If you do not want to see the effect he would have (as described in the post above), leave it in the source report, add a text element of P2_REPORT_SEARCH, and a button "submit" on page 2 and experimenting to find different values of the element and clicking on the submit button...

• Help with APP_USER in SQL query

  Hello
  
  I would like to extract a detail of the user in a form of language element DML based on the logged in user and the standard authentication scheme.
  
  I make this request in the element:
  

   select ANALYST_FIRST_NAME ||' '|| ANALYST_LAST_NAME d, ANALYST_ID r from QTMT_ANALYST where EMAIL = :APP_USER 

  The user in the session is equal to the value of the EMAIL. In fact, the value in the session is a capital letter, and the other in the database is tiny. I think that's irrelevant anyway.
  
  The query do not of any value. Could you please let me know what I did wrong?

  Item Source type: query SQL (single return value)
  
  Thank you and best regards,

  To be on the safe side you should uppercase both sides of the equation. It could be that the user name is entered in lowercase.

  But if you think that your request is correct, test it by using a literal rather than the user name.

  select ANALYST_FIRST_NAME ||' '|| ANALYST_LAST_NAME d
  from QTMT_ANALYST
  where upper(EMAIL) = upper(:APP_USER);
  

  for testing purposes, use something like this:

  select ANALYST_FIRST_NAME ||' '|| ANALYST_LAST_NAME d
  from QTMT_ANALYST
  where upper(EMAIL) = upper('[email protected]');

  Item Source type: SQL Query ( return a single value )

  I just noticed that you use an element that has this as the SQL source. This only works if the sql returns a row and a column only. That's why I removed the second column in your query.

  With the help of SQL does not mean a faster CASE statement, or a faster TO_CHAR(), PL/SQL.

  So if you have 10 instructions BOX , which must be run once 1000, SQL and PL/SQL are just as fast.

  So, why then do you prefer SQL?

  Because for the statement SQL CASE , to assess data comes directly from the line being processed by that SQL.

  Instead, one must use a SQL statement to retrieve the data for PL/SQL. The data travels all the way from this line, via the SQL, in memory of the PGA of PL/SQL. And only then PL/SQL can apply the CASE statement.

  If performance differ not because the CASE statement is faster in one language than another, but because of the way that data gets the code in this CASE .

  My question is to what extent I should stop writing SQL and then mix it with PL/SQL? TX in advance.

  There is no rule set to be applied to answer this question. Also, keep in mind that SQL and PL/SQL can be mixed differently.

  Create PL/SQL functions (for example business rule/translation) and call this function of SQL.

  Pull the lines as is the SQL cursor in the memory of the PGA of PL/SQL and then Pat PL/SQL functions on these data from PGA (aka bulk collection).

  Create a PL/SQL function, where the SQL engine provides (via a slider interface) lines of the pipeline in the pipeline, PL/SQL does little, then driven back a line of response to the SQL engine.

  So it comes down to it depends..

  Remember, there is no order integrated to the rows in a table.  The table you have posted is exactly the same as:

  AA bb

  --    --

  1 FG

  1 FG

  2 SS

  1 FG

  1 FG

  and both are exactly the same as:

  AA bb

  --    --

  2 SS

  1 FG

  1 FG

  1 FG

  1 FG

  If you use words like 'first', 'previous' or 'row' when it comes to lines, then we must define what these words mean.  This is usually done by making reference to a column in the table.  For example, if you had a column called r_num, like this:

  AA bb r_num

  --    --    -----

  1 FG 1

  1 FG 2

  1 FG 9

  2 SS 10

  1 FG 10.5

  Then, it would be wise to say things like 'the table starts with 3 lines consecutive "FG", followed by "SS".  After that there is another "FG", which is the last line in the table, WHEN TRIE BY R_NUM.   If the part about "WHEN SORTED BY R_NUM" is not known, the words 'begins '. "consecutive", 'followed', 'after' and 'last' have no meaning.

  If (and only if) you have somehting like r_num in your table. Then you can get the resutls you want like this:

  WITH got_group_num AS

  (

  SELECT aa, bb, r_num

  ROW_NUMBER () OVER (ORDER BY r_num)

  -ROW_NUMBER () OVER (PARTITION BY bb

  ORDER BY r_num

  ) AS group_num

  FROM table_x

  )

  SELECT SUM (aa) AS total_aa

  ,         bb

  OF got_group_num

  GROUP BY bb

  group_num

  ORDER OF MIN (r_num)

• SQL query for the apex report

  Hi team,
  
  For example if I have a demo table with 4 columns (A, B, C, D) DEMO.
  
  I want a report on this table, such that the report contains the headers and the Details section.
  
  For each unique combination of (A, B) I must first of all show header based on the header information I want to display the detailed section.
  In my header section I want to display 2 columns (A, B) that are common to the detailed section. Remaining 2 columns in the detailed section.
  
  
  Here is an example: -.
  
  A B C D
  1 5 9 3
  1 5P8
  1 5 P O
  1-5-9
  1 8 9
  1     D     *     /
  2 8 33 P
  2 P O O
  2 P L L
  
  YOU WILL SEE
  A AND B
  1 5
  
  C D
  9 3
  P 8
  P O
  
  
  A AND B
  1 D
  
  C D
  5 9
  8 9
  *     /
  
  
  
  A AND B
  2 P
  
  C D
  8 33
  O O
  L L
  
  Please suggest the solution (sql query) for above the problem and how to nest gernerated headers dynamically in the report area.
  I use APEX 4.0
  Any position in this regard is very significant.
  
  Thanks and greetings
  Rajendra

  Try this:

  SQL> select * from tab;
  1 5 9 3
  1 5 P 8
  1 5 P O
  1 D 5 9
  1 D 8 9
  1 P 8 3
  1 P O O
  
  7 rows selected.
  
  SQL> select a,b from
  (select r,a,b from
  ( select to_char(rownum)||'a' r, 'A' a,'B' b from
          (select distinct a, b from tab order by a,b))
          union
  ( select to_char(rownum)||'c' r, 'C' c,'D' d from
          (select distinct a, b from tab order by a,b))
  union
  ( select to_char(rownum)||'b' r, a,b from
  (select distinct a, b from tab order by a,b))
  union
  select parent.r, tab.c, tab.d from
  ( select to_char(rownum)||'d' r, a,b from
  (select distinct a, b from tab order by a,b)) parent ,
  tab
