• A report from a query using the Union

  Hello. I try to select an account for this request and then to display the total in a message, but I'm getting one too many returned lines (ORA-01422). Can someone tell me how I can get a total for this request?

  Any help would be greatly appreciated.

  Hello
  first: your Union will always return two rows
  Second: there is no need to put a nvl() because a county will always return o If nothing with the criteria.

  select count(1)
  into v_1
  from table1;
  select count(1)
  into v_2
  from table_2;
  conflict_cnt = v_1 + v_2;
  /* that(s it !*/

• selection of a single record using the UNION

  Hello. I have two tables different 'address' (home and work). In some cases, a person will have a record in the two arrays 'address', while some people will have only a record in one or the other. I want to return a single record set by b.SID. So if a person has a criminal record in the two tables then I'm just grabbing a name and an address. How can I do this?
  
  Select b.SID, b.address
  people a, b House
  where b.name = b.SID
  UNION
  Select b.SID, b.address
  people, work b
  where b.SID = b.name;

  something like

  select a.name, NVL(b.address, c.address) address
  from people a, home b, work c
  where a.name = b.name(+)
     and  a.name= c.name(+)

• Alternative to the union in Oracle 10 g

  Here's the sql code using the union that I currently use. There are 64 columns of 3 different tables. Out of all the columns that a single column value is a constant for 2 discs.
  
  Select col1, col2, col3,..., 'TO' medium_val
  of table1, table2, table3
  where table1.col1 = table2.col1
  and table2.col1 = table3.col1
  and other criteria
  Union
  Select col1, col2, col3,..., 'GT' medium_val
  of table1, table2, table3
  where table1.col1 = table2.col1
  and table2.col1 = table3.col1
  and other criteria
  
  Basically repeating the same code just for the value of a column. Is there any alternative to the union in order to avoid the questioning of two times the same tables.

  Hello

  Here's one way that will work in Oracle 9 (or higher):

  WITH     all_medium_vals     AS
  (
       SELECT  'DE' AS medium_val     FROM dual     UNION ALL
       SELECT     'WG'                FROM dual
  )
  SELECT  col1, col2, col3, ....
  ,      m.medium_val
  FROM      table1
  ,      table2
  ,      table3
  ,     all_medium_vals  m
  WHERE      table1.col1      = table2.col1
  AND     table2.col1      = table3.col1
  AND     ...
  ;
  

  Do not refer to m.medium_val in the WHERE clause. Leaving him out, you'll do a cross join of your result set of table1, table2, and table3 with 2 lines in all_medium_vals.

  Starting Oracle 11, there are also SOME... UNPIVOT.

  You will notice that this query is still a UNION, but it's just the UNION of two lines and then by doing the complicated only one query. That will be much more effective that make the complex query twice, and then make a UNION of however many lines that happened to produce. There are ways to generate all_medium_vals without a UNION, but they are not as easy to understand or to debug and are not significantly more effective.

  That is to say, this type of result, we can produce with this:

  Hey Shiva,

  Copied from documentation

  Restrictions on operators define the set operators are subject to the following restrictions:

  • Set operators are not valid on columns of type BLOB , CLOB , BFILE , VARRAY , or a nested table.
  • The UNION , INTERSECT , and MINUS operators are not valid on LONG columns.
  • If the selection list prior the operator set contains an expression, you must provide an alias for the expression column to refer in the order_by_clause .
  • You cannot specify also the for_update_clause with the set operators.
  • You cannot specify the order_by_clause in the subquery of these operators.
  • You cannot use these operators in SELECT statements containing the TABLE expressions collection.

• Columns of Union two problem using the TO_CLOB function

  Hello
  
  Let me start by you (a simplified version of) showing the query I'm running:
  
  SELECT
  l.Person,
  TO_CLOB(l.letter_code ||) "letter has been sent.") Note
  letters l
  
  UNION
  
  Select
  n.Person
  n.Note
  n notes
  
  And here's the table structure

  l.Person varchar2 (10);
  l.letter_code varchar2 (2);
  *)*
  
  NOTES)
  n.Person varchar2 (10);
  CLOB n.note;
  *)*
  
  Each request runs on its own without any problem but when I union together I get a ' * ORA-00932: inconsistent data types: expected - got CLOB * "error. I can't understand what is the cause. The TO_CLOB in the first query is to convert the varchar2 column in a CLOB then why would he be oppose to be clauses with the second query?
  
  Any advice would be much appreciated! Thanks :)

  You may not use the set operations, UNIONS, MINUS, INTERSECT with CLOB columns etc. simple as that.

  Hello

  Think very carefully about why you need to do this in SQL * more.
  Because you need an automated process, PL/SQL would be better?
  When you use UNION, you cannot ORDER BY something that is not in the SELECT clause. You can easily assign a sort key in every branch of the UNION and use SQL * more control "COLUMN sort_key NOPRINT" to prevent it to appear in the output, even if it has as a result set.

  In pure SQL, you can make the UNION in a subquery, then the main query (with the ORDER BY clause) does not need to include the sort key in the output:

  WITH     union_data     AS
  (
       SELECT      'drop user '
            || username
            || ' cascade;'                    AS sql_txt
       ,          username || ' 1'               AS sort_key
       FROM     dba_users
       WHERE     username     IN ('S_DMJ','S_MBIN','S_URTL')
      UNION
          SELECT  'alter database datafile '
            || file_name
            ||' RESIZE 5M;'                    AS sql_txt
       ,          tablespace_name || '2'               AS sort_key
       FROM       dba_data_files
       WHERE      tablespace_name IN ('S_DMJ','S_MBIN','S_URTL')
      UNION
       SELECT  'DROP TABLESPACE '
            || tablespace_name
            || ' INCLUDING CONTENTS AND DATAFILES;'     AS sql_txt
       ,          tablespace_name || '2'               AS sort_key
          FROM      dba_tablespaces
       WHERE     tablespace_name     IN ('S_DMJ','S_MBIN','S_URTL');
  )
  SELECT       sql_txt
  FROM       union_data
  ORDER BY  sort_key
  ;

• Is it possible to use the title of column sorting along w / a union?

  When I had a simple select statement, I might get the kind work with either one "in order to" in the select statement or with sorting of the column header.
  Then, I changed the select a Union. I can get the folders to sort if I specify the column number in the order (for example, the order of 9, 7, 1), but the position column sorts do not work. The records look like they are sorted on page 1, but are not sorted on pages 2-5.
  Is it possible to use the title of column sorting and a Union?
  
  Thank you!

  Laura:

  You can re-write the query in the form

• Using the RPD Union queries

  Hello

  I need in which I table based on active groups, that is, each group is to have a separate table.

  Now my reports queries all active groups. How to design in the RPD.

  * We are unable to build the union of all reports.

  Let's take an example

  A group table

  Group key

  Column1

  Column2

  Group B table

  Group key

  Column1

  Group C table

  Group key

  Column2

  Column1 and column2 here's respective information, but for groups of various assets (is there, we have 3 tables)

  The tables of dimensions.

  Tried to make paintings like LTS for a single logical table. But the query consists of a single table with two columns

  Thanks in advance

  1 table of logic with several (NOT an LTS with several joined tables) LTSS valued content of their respective fragmentation.

  Update: and don't forget to put "this source must be combined with other sources at this level" = TRUE

• Use the value of the sum and compare

  I have a table with data below

  If my table has a
