• update of column based on the sum of the data from another table

  I have two tables:

  Table1 (col1, col2, col3, col4, val1, status) Table2 (col1, col2, col3, col4, val2)

  For Table1 and Table2, column (col1, col2, col3, col4) are the primary key of composit.

  Table2 could have duplicated lines, that's why I want to group by (col1, col2, col3, col4) and sum (val2)

  After that, I want to update Table1.val1 with the value of sum (Table1.val2) where Table1.col1 = Table2.col1 and Table1.col2 = Table2.col2 and Table1.col3 = Table2.col3 and Table1.col4 = Table2.col4 and status = 'V '.

  I did something like this:

  UPDATE Table1 SET val1 = (

• How to update one column from another table

  Hello

  We have some sellers who are defined as employees but without employee_id for some reason any.  So I would like to update the correct number of a view of HR records.  Here is what I tried:

  update of po.po_vendors x

  Define employee_id = (select apps.per_people_v7 person_id y)

  where y.first_name |' '|| y.last_name = x.vendor_name)

  Error received: a row subquery returns more than one line.

  If I use this instruction to check, I'm correct employee_id or person_id home:

  Select apps.per_people_v7 person_id y, po.po_vendors x

  where y.first_name |' '|| y.last_name = x.vendor_name

  When I checked/compared with some old posts here, I could not just see where I did mistake.  Please notify.

  Thank you

  Ning

  Because for the same vendor id, you have a (employee id) id of the person twice in the target table. As Boneist said "fix data, difficulty of the request, fix the requirement...". »

• read in select data from another table

  Hello world.

  IM Oracle11GR2 database.

  I m facing the following problem:

  I have 2 tables.

  In the first picture, I have a few articles and 3 of these items then come.

  (A) point Varchar2

  (B) Item Varchar2.

  (C) point digital and this point is the id of a record in the other table.

  If the digital point > 0 then points A and B must be read in the second table

  In the second table, I have 3 Articles.

  (A) the id of the record.

  B & C point are also point varchar2 and must be read in the first table, point C is > 0.

  I'm looking for the way that when I write a normal selection in the first picture he gives me the point B & C of the second table if C point in the first table is > 0.

  I thought to solve this problem with a trigger or something similar.

  Any idea is welcome.

  Regards to everyone.

  You don't need a trigger for this. A simple select statement should do. Something like that? I got your if condition perfectly.

  SELECT CASE WHEN (T1. C > 0) THEN (SELECT T2. B OF THE T2 WHERE T1. C = T2. (A) T1 OTHERWISE. END A,

  BOX WHEN (T1. C > 0) THEN (SELECT T2. C FROM T2 WHERE T1. C = T2. (A) T1 OTHERWISE. B END HAVE B,

  T1. C

  FROM T1;

  Look at the following example. Check if it fills your scenario.

  -BEGINNING OF THE SAMPLE DATA

  WITH T1 AS)

  SELECT 'A' A, 'B' B, 1 C OF DOUBLE UNION ALL

  SELECT 'C', ', 2 DOUBLE UNION ALL

  SELECT 'DF', 'G', THE DOUBLE 0),

  () AS T2

  SELECT 1, 'X' B 'Y' C DOUBLE UNION ALL

  SELECT 2, 'Z', 'BB' OF THE DOUBLE)

  -END OF THE SAMPLE DATA

  SELECT CASE WHEN (T1. C > 0) THEN (SELECT T2. B OF THE T2 WHERE T1. C = T2. (A) T1 OTHERWISE. END A,

  BOX WHEN (T1. C > 0) THEN (SELECT T2. C FROM T2 WHERE T1. C = T2. (A) T1 OTHERWISE. B END HAVE B,

  T1. C

  FROM T1;

  OUTPUT:

  A  B           C

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

  X Y 1 - since c > 0 A and B values in table 2 are replaced

  Z BB 2 - since c > 0 A and B values in table 2 are replaced

  DF G 0 - since c = 0, there is even value in table 1

  Is that what you're trying to do with the insert. I think there may be a sign {noformat}<{noformat}{noformat}>{noformat} missing in the where clause. This site eat those, so you need to use the equivalent! = post here.

  If I'm wrong about the missing trader, then it looks like you want to insert rows in temp_ivan_mary that are not already in top_prospects. If Yes, then you need something like:

  insert into top_prospects
     (common_id, date_added, review_rank, eval_date, pm_assign,
      why_notes)
  select t.common_id, t.date_added, t.review_rank, t.eval_date,
         t.pm_assign, t.why_notes
  from temp_ivan_mary t
  where t.common_id not in (select common_id from top_prospects
                            where common_id is not null)
  

  Function index and data available volumnes etc. then a mergr can be more effective. Something like:

  merge into top_prospects p
     using (select common_id, date_added, review_rank, eval_date,
                   pm_assign, why_notes
            from temp_ivan_mary) t
     on (p.common_id = t.common_id)
     when not matched then
        insert (common_id, date_added, review_rank, eval_date, pm_assign,
                why_notes)
        values (t.common_id, t.date_added, t.review_rank, t.eval_date,
                t.pm_assign, t.why_notes)

• Migration of data from a table to another table

  have a table1 that includes the existing data in the format.
  
  ~@!%~X1~@!%~Y1 in three different coulmns
  
  creates a new empty table and the need to migrate the data above, which is present in 3 different columns in a column in the new table, as shown in the example below.
  
  table 1 existing data (| separator of columns for formatting)
  ------------------------------------------------------------------------------------------------------------------------------------
  ID name1 | Name2. Name3
  123 ~@!%~X1~@!%~Y1 | ~@!%~X2~@!%~Y2 | ~@!%~X3~@!%~Y3
  234 ~@!%~X4~@!%~Y4 | ~@!%~X5~@!%~Y5 | ~@!%~X6~@!%~Y6
  456 ~@!%~X7~@!%~Y7 | ~@!%~X8~@!%~Y8 |     ~@!%~X9~@!%~Y9
  
  
  Table 2, which will initially be empty and after migration, it should look as follows.
  
  ID name1
  ----------------------------------------------------------------------------------------------------------------------------
  123 ~@!%~X1~@!%~Y1 & & ~@!%~X2~@!%~Y2 & & ~@!%~X2~@!%~Y2
  234 ~@!%~X4~@!%~Y4 & & ~@!%~X5~@!%~Y5 & & ~@!%~X6~@!%~Y6

  as shown in the example above
  
  Name1 column has ~@!%~X1~@!%~Y1
  Column name2 has ~@!%~X2~@!%~Y2
  Name3 column has ~@!%~X3~@!%~Y3
  
  Once the data is migrating from table 1 for id - 123 looks like below, before joining data from 3 tables, I need apopend & & for each for the token I read of the tabl1 of name1 to end ii should be added "& &" also when I read the name2 I add "& &" at the end of the string before the concatination.
  
  Here's the sample that deals with data for id - 123 with & & (only & & other symbols are part of the data)
  
  ~@!%~X1~@!%~Y1 & & ~@!%~X2~@!%~Y2 & & ~@!%~X2~@!%~Y2

  Hello

  You are looking for something like this

  CREATE TABLE table_new
  AS
     (SELECT id, name1 || '&&' || name2 || '&&' || name3 name1
      FROM table1);
  

  or if you have the table ready

  INSERT INTO table_new
     (SELECT id, name1 || '&&' || name2 || '&&' || name3 name1

• Update multiple columns from multiple tables in a single UPDATE request

  Hello

  I'm trying to figure if I'm heading in the right direction.

  I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.

  Scenario 1

  UPDATE Table2, Table 3
  SET T2.Column1 = T1.Column1 
  ,T2.Column2 = T1.Column2
  ,T3.Column2 = T1.Column2
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T1.id = T2.id
  and T1.id = T3.id
  
  

  Scenario 2

  UPDATE Table3
  SET T3.Column1 = T1.Column1 
  T3.Column2 = T1.Column2
  ,T3.Column3 = T2.Column3
  ,T3.Column4 = T2.Column4
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T3.id = T1.id
  and T3.id = T2.id
  
  

  Hello

  For scenario 1, you must write separate instructions UPDATE table2 and table3.

  To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

  ENGAGE only when two tables have been changed.

  You can write a procedure or an INSTEAD OF trigger to do all this.

  For scenario 2, you can reference many tables that you need when new table3.  It might be more efficient and simpler to use the MERGER rather than UPDATED.  For example:

  MERGE INTO table3 dst

  WITH THE HELP OF)

  SELECT t1.id

  t1.column1

  t1.column2

  t2.column3

  t2.column4

  FROM table1 t1

  JOIN table2 t2 ON t1.id = t2.id

  )             src

  WE (dst.id = src_id

  WHEN MATCHED THEN UPDATE

  SET dst.column1 = src.column1

  dst.column2 = src.column2,

  dst.column3 = src.column3,

  dst.column4 = src.column4,

  The procedure allows for the header and the data to separate files if necessary. Just by specifying the file name "header" will put the header and the data in a single file.

• Populating one table from another table

  Hi Forum...
  
  I'm trying to populate a table from another table using CFQUERY... I have no problem with the selection of data from the original table, but need help to get the data into the new table. I use MX 6.1 and access as the database server.
  The two arrays have domain names identical to the same place, and I don't want to have to code all the column names in the selection and insert command. for example
  
  < cfquery name = "GetData" datasource = 'somename' >
  SELECT * FROM AssetTable1 WHERE BarCode = "123456".
  < / cfquery >
  
  < cfloop query = "GetData" >
  < cfquery name = "InsData" datasource = 'somename' >
  INSERT INTO AssetTable2 (xxxx...)
  VALUES ("#xxxx... #'")
  < / cfquery >
  < / cfloop >
  
  I hope this makes sense
  
  Thanks in advance

  If your tables are identical structures and their columns are of the same type and position, and both tables are in the same database, then put everything in a single query.

  
  INSERT INTO AssetTable2
  SELECT *.
  OF AssetTable1
  WHERE bar code = "123456".
  

  If the columns were in different positions, then you should be listed explicitly in the INSERT and SELECT the parts, but you get the idea.

  INSERT INTO table1 (col1, col2)
  SELECT col1, col2
  FROM table2
  WHERE all that...

• Import data from another browser - only a few favorite IE9 are transferred in bookmarks. Solution HTML - HTML file all Favorites OK, but same result

  Win7 / IE9: use for the first time. Example: A folder of Favorites has 4 entries HTML - only 2 transferred. Some have none transferred - empty folder. Others have correct random + some disappeared persons.

  All of Monday
  I can see the full list of favorite IE9 HTML in HTML file on desktop with Firefox-> new tab-> open file-> open
  .
  In the desktop HTML file, there are 37 files IE9 with no more nesting 3 deep in all of a high. They are all correct wrt favorite IE9.

  All records albums + deeper nests are copied in FF ok. Random content. Copied content works ok

  7 unassigned to IE9 HTML web sites best records are also copied <-these 7 copy on FF and work well

  Example: First file in the list of IE9 has no nesting., IE9 has 4 entries - Firefox has only 2. What other method of reproduction is used.

  BTW - please let know us how I can delete entire list of bookmarks in Firefox button to try again with a clean list of bookmarks

  I'll uninstall Firefox and start over with a clean copy and use the HTML only method to try to transfer IE (files. I'll bring result.

  BTW, I'm in the United Kingdom at the time of UK - where delays to answer - need to sleep sometime!

  Hello

  I uninstalled Firefox. Re installed and loaded with favorite IE9 to HTML file.

  All seem to be copied correctly

  First time that I started using the "import data from another browser. Partial is copied.
  Then I tried 'Import HTML file' without deleting any favorite had been copied. Always partial copied.

  Everything seems fine.

• When you try to import the bookmarks, the ability to import data from another browser is not active in the import and backup from the tap in the history. So, how to import bookmarks on my file?

  I followed the instructions of Firefox to import bookmarks/favorites to Internet Explorer. It does not work because the import data from another browser is not active in the import tab and backup in the history. The instructions read to use this tab, but does not work because it cannot be selected.
