• WITH THE HELP OF SEPARATE OR ONE GROUP WHEN IN PRIMARY KEY CLAUSE

  I WANT A WAY TO EFFECTIVELY PERFORM AGGREGATE FUNCTIONS ON A PARTNER OF THE PARENT TABLE CHILD TABLE AND RETURN ALL THE COLUMNS IN THE PARENT TABLE AND CALCULATED FROM THE CHILD TABLE COLUMNS.
  
  THE PROBLEM IS THAT WHEN I USE GROUP BY ON ALL FIELDS IN THE PARENT, INCLUDING THE PARENT TABLE TABLE, I THINK THAT ORACLE TESTS ALL THE COLUMNS IN THE GROUP BY CLAUSE WHEN IT SHOULD GO HAS THE PRIMARY KEY MAKES ALL IMPLICITLY SEPARATE LINES.
  
  I CREATED TWO TEST TABLES AND RRAN SOME QUERIES TO TEST AT THE SAME TIME.
  
  HERE ARE THE TABLES:
  
  CREATE TABLE A_PARENT_TABLES

  HOW CAN I ACHIEVE THE EQUVILENT OF THE FIRST QUERY IN A WAY MORE EFFECTIVE?

  Hello

  As you can see on the plain explain command
  This full table scan done query1 on A_PARENT_TABLES
  query2 done index range scan on A_PARENT_TABLES

  This is one of the reasons why query2 runs faster than the application 1.

  Why complete analysis of table to query1?
  Its because you want in query1 to display other fields present in A_PARENT_TABLES and is not present in the primary index of this table, that is why he must go to the table for the data.

  Hope this helps.

• Mail has stopped allowing me to use Group addresses

  I'm under El Cap 10.11.6.

  Mail left allowing me to use Group addresses. I tried manually, type the group name in the address bar, add the group by using the + function and click and drag.

  When I use the + function, the group is displayed but cannot be selected.

  What is the solution?

  Plot thickens: when I manually add recipients to the BCC line, the email will send but is never received by anyone on any address line.

• After using groups of tabs earlier today, now whenever I close FF with more than 1 open tab, FF don't ask me to confirm before closing

  After using groups of tabs earlier today, now whenever I close FF with more than 1 open tab, FF don't ask me to confirm prior to closing. FF always asked me to confirm in the past and no settings have been changed before you try tab groups. Then when I open FF it again all the tabs I had open are still there. I tried refreshing FF and erase history, but that did not work. It's almost as if FF think windows and tabs I have open are a group of tabs, and he won't let me get rid of this group. How to stop groups of tabs now that I have them? Or is there something else? None of this was going on until this morning, I played with tab groups. I was curious what it was - it's going to make me kill one of these days lol.

  Note that using "show my windows and tabs from last time" as the start setting will also prevent Firefox to display an alert when you close the window.

  Hi all

  We strive map drives using Group Policy on our image of Vista. (In the past, we have used kixtart, but try to avoid writing scripts).

• Problem with subtotal and grand total using GROUP BY ROLLUP.

  Hi all

  I have a question about the SQL. I need to have the subtotal for each group and total for the entire inside of my request. I've had using GROUP BY ROLLUP to have total subtotal and big inside of my request.

  However, it not successful I want. In addition, my data must be presented in the medium hierarchy. So, I also use CONNECT BY permission inside my request.

  The query returned the results but not as my expected.

  Below is all about the tools used, description of flows, issues, query used, sample data, out of the request as well as the expected results: -.

  Tools used: -.

  • Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

  Description of the flow: -.

  Lily is an AM of agency which is the highest level of management (LEVEL 1). Kevin is the direct agent under the lilies and the sum of productivity(upstream)

  for each of them must be sum up as the Subtotal. Sarah and Tom is the Unit Manager (UM) (LEVEL 2) who reports to Lily. They have the direct agents (Agent) under each of them which are may, John, Sue and Salwa (LEVEL 3).  There should be a Subtotal for each group of the agent. For example:-May (Agent) is the agent under Sarah (UM) and both of them have productivity and productivity should be sum up as a subtotal for the core group. A GRAND TOTAL is required to summarize all the productivity for each group.

  Problem: -.

  1. The output of my query is appear the subtotal, but the amount is inaccurate because it only to summarize the productivity of agent. The output I expect is summarize the productivity of the agent as well as UNIFIED messaging / AM. For example:-(subtotal = UM / AM.) THE PRODUCTIVITY + AGENT. PRODUCTIVITY)
  2. The total general does not show after the query. The output that I expected is productivity for each groups as shown in the attachment below.                                                   For example:- GRAND TOTAL =(SUBTOTAL+SUBTOTAL+SUBTOTAL)
  3. My data must be submitted in respect of the hierarchy as below: -.

  

  4. I need to pass the variable in the query and be used as a parameter in the ADF. Agent ID of Lily(AM) pass in the variable as a parameter.

  Here's my query: -.

  Hello

  I still don't know how you want to trunking.  You want someone who has a tank of 'AGENT' that lie with its parent in the hierarchy?

  If Yes, you can do the update ROLLUP before you make the CONNECT BY query and claim that summaries are the children of one of the actual lines in the tree, like this:

  WITH got_grp_id AS

  (

  SELECT b.SID, a.upline

  TO_CHAR (a.agent_id) AS a_agent_id

  CASE

  WHEN a.agent_rank = "AGENT".

  AND a.upline IS NOT NULL

  THEN a.upline

  Of OTHER TO_CHAR (a.agent_id)

  END AS grp_id

  p.total_manpower, p.mtd_total_anp

  Of abm_agent_test one

  abm_productivity p

  WHERE a.agent_id = p.agent_id

  )

  got_aggregates AS

  (

  SELECT THE CHECK BOX

  WHEN you GROUP (name) = 0

  THEN the name

  WHEN you GROUP (grp_id) = 0

  THEN "SUBTOTAL".

  ANOTHER "GRAND TOTAL".

  END AS name_s

  CASE

  WHEN you GROUP (upstream) = 0

  THEN upstream

  WHEN you GROUP (grp_id) = 1

  THEN TO_CHAR (: a).

  Of OTHER LAST_VALUE (a_agent_id IGNORE NULLS)

  COURSES (PARTITION BY grp_id

  ORDER OF CASES

  WHEN a_agent_id <> grp_id

  THEN SUM (mtd_total_anp)

  END NULLS FIRST

  ROWS BETWEEN UNBOUNDED PRECEDING

  AND UNBOUNDED FOLLOWING

  )

  END AS parent

  a_agent_id, grp_id

  SUM (total_manpower) AS sum_total_manpower

  SUM (mtd_total_anp) AS sum_mtd_total_anp

  Group of (name) AS g_name

  GROUPING (grp_id) AS g_grp_id

  OF got_grp_id

  GROUP OF ROLLUP (grp_id

  , (name, upstream, a_agent_id)

  )

  )

  SELECT THE CHECK BOX

  WHEN g_grp_id = 0

  THEN LPAD (' ', 4 * (LEVEL - 1))

  END | name_s AS first_nameq

  sum_total_manpower

  sum_mtd_total_anp

  CASE

  WHEN g_name = 0

  THEN THE LEVEL

  4 SOMETHING ELSE

  END as lvl

  a_agent_id

  OF got_aggregates

  START WITH a_agent_id = TO_CHAR (: a).

  Parent = a_agent_id PRIOR CONNECTION

  Brothers and SŒURS of ORDER BY sum_mtd_total_anp

  Salwa 1 75000 3 109

  PARTIAL TOTAL 4 158000 4

  GRAND TOTAL 8 314000 4

  I changed the column names.  (For example, there is a built-in function called RANK, so this isn't a column name good.  "It's confusing to use upstream to 2 unrealted stuff.)

  I guess just what you want for the LVL column.

  Why is agent_id a NUMBER, but upstream a VARCHAR2?  I expect to be of the same data type, so that upstream may be a foreign key referencing agent_id.

• What is the equivalent of | operator using the Q-quote mechanism?

  Version: 11.2.0.3

  I started a thread on similar requirement last week. I didn't want to resurrect. So, I start a new thread.

  We have a stored procedure called generate_table_stats that meet the stats for tables with a few additional options.

  Usually, this procedure is performed as below

  generate_table_stats exec ('EMP_DTL', 'BASIC');

  We want to generate the exec above instructions dynamically for all tables.

  In the traditional method of quotations, we use the concatenation (|) operator to separate the column names whose values are retrieved dynamically from the table queried.

  Similarly, how can I get a column of values printed when you use the Q-quote mechanism?

  In my column in table_name attempt below must be retrieved from user_tables. But table_name and pipes that are treated as literal string (which is not surprising).

  What is the equivalent of | (concatenation operator) when you use the Q-quote mechanism?

  -Expected results

  generate_table_stats exec ('EMP_DTL', 'BASIC');

  generate_table_stats exec ('CUSTOMER_DTL', 'BASIC');

  .

  .

  .

  -My attempt using Q-quote

  -Using # as the quote delimiter

  SQL > select q'#exec generate_table_stats ('| table_name |', 'BASE'); #' From user_tables;

  Q' #EXECGENERATE_TABLE_STATS('||) TABLE_NAME |', 'BASE')

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

  generate_table_stats exec ('| table_name |', 'BASE');

  generate_table_stats exec ('| table_name |', 'BASE');

  generate_table_stats exec ('| table_name |', 'BASE');

  generate_table_stats exec ('| table_name |', 'BASE');

  .

  .

  .

  .

  Hello

  The concatenation operator. works the same with any string expression.

  x | There

  Returns a string that is the same as sting followed immediately the string x y, x is

  • a literal string with Q before the first single quote
  • a literal string without Q
  • a VARCHAR2 column
  • a function that returns a string, or
  • any string expression.

  The string can be everything above, too.

  If you concatenate strings of 3 or more, like this

  str1. str2. ... || Suro

  then each of the STRS can be any kind of expression, independent of others.

  If you want to concatenate strings of 3, the 1st and the 3rd being Q-literals and the 2nd being a column, you can do it like this:

  Select q' generate_table_stats #exec (#' | table_name)

  || q ' #, ' BASIC'); #'

  From user_tables;

  Each of literals has its own Q and her own pair of start and end markers (all the ' # s in the example above).

  Since the first string literal has no any single-quotation marks incorporated, it is unnecessary to use Q-rating, and it could be misleading; a person who bed the code might think the actaully string contains ' #'s.  I prefer wriite the query in the form

  Select ' generate_table_stats exec (' | table_name)

  || q ' #, ' BASIC'); #'

  From user_tables;

  Hello

  Thanks for posting the CREATE TABLE and INSERT statements; This is really useful!

  Your volumninous sample data are all for a month. Since your first query is grouped by month, I suppose that this is not always the case.
  In this case, you can make GROUP BY queries on two tables separately, in two subqueries, then join the results.
  For the separate columns for the values of mv_zone_hoiurly, I GROUP BY the name of tag in the subquery, then their pivot in two columns in the query of amin.

• separate account using the lookup table

  How can I get a separate count of column values by using another table?
  
  Let's say I want to get a separate account of all 'company_name' files in the 'emp' table that corespond (soccer match) with table of 'research', 'State' category.
  
  What I want is to find charges for all businesses that have a value of 'california' in the 'Status' column of the 'search' Table. I want the output to look like:
  
  Sears 17
  Pennys 22
  Marshalls 6
  Macys 9
  
  I want the result to show me the company names dynamically as I don't know what they are, just that they are part of the group 'State' in the lookup Table object. Does make sense?

  If you want a counter for each value of rfs_category, but instead of rfs_category you want to display, it's translated value lookup_value_desc.

  This should do it for you:

  select lookup_value_desc, the_count
    from lookup
    join (select rfs_category, count(*) the_count
            from RFS group by rfs_category)
      on rfs_category = lookup_type;

• Using groups of Windows Mail contacts without displaying the FIELD email addresses; and without having to use the BCC field?

  I want to see all the names of everyone in the group in the TO field: only the names of individuals in the Contact Group and NOT to display their individual addresses alongside their names; and I don't want to use the BCC field (because it will appear all the names). Is this possible?

  Unless you have included their address in a part of the field name, the addresses must disappears from view when sending. That said, all they need do is click on transfer, reply to all, or view the message source and they see all the addresses. That's why the BCC option was created. Bruce Hagen

• How can I associate with other separate articles, using the publishing tools digital adobe?

  All items are collected in folio Builder. I know how to put a link in an article, but not to the other separate articles. I want to put a text link in the index of my magazine to the landing page. I have Indesign CC. Please, can you help me?

  This is correct to a links Panel example. You should check the shared button hyperlinks. This example goes to a specific page in an article. The article name should be the name of the article in Folio generator Panel. Your names are not similar there are spaces. Remove the spaces or use underscores.

  

  Here is an example of a button. You use go to URL not go to Destination.

  

  The navto coding convention is the same for the buttons and hyperlinks.
