• SQL multiple columns in a single row

  Hi all
  
  I have 2 tables, product and Product_Name, a product can have several names.
  
  I need to recover what I show the Product_ID followed by all the names of this product has.
  
  I am not able to do, every way I try get the product ID duplicated several lines with a name of different product on each line as follows:
  
  ' 1, ' iron Z.
  1, "iron M.
  1, "iron N".
  2, 'wood P.
  2, 'wood M.
  
  What I need is:
  
  1, Z, M iron, iron N
  2, wood P, wood M
  
  Thank you and best regards.

  Thanks for the reply from Frank,

  Iron Z, iron and iron N M would be 3 different entries in the same column.

  I'm sure that the LISTAGG function should solve this problem, the problem is that I expected to find a solution on pure SQL or PL/SQL, perhaps with a nested Select statement.

  My version of Oracle's 10g Express Edition.

  LISTAGG is pure SQL, but it was introduced only in Oracle 11.2. All mentioned below should work in Oracle 10.

  The STRAGG from this page is very useful. You must copy and install approximately 60 line of PL/SQL code. Do it once, and then you can use hundreds of times in hundreds of motions, as if it were a built-in function. The main problem with STRAGG, it is difficult to get the output soprted. There is a modified version, designed for output sorted on this thread:
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:15637744429336
  Never used. Can't vouch for it.

  SYS_CONNECT_BY_PATH seems to be the most popular way after the aggregation of the chain in Oracle 10. The example given on the page of the Oracle Base (that I posted in my last post) is a little clumsy and inefficient. See the next thread for a better example, using CONNECT_BY_ISLEAF:
  Re: Concatenate strings more lines in a single line.
  or, now that I see it, Pollywog example above.

• display of the values of column in a single row

  Hello
  
  Can you give me please workarounds for this problem:

  Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
  -- sample data
  CREATE TABLE TEST_DATA
  (
    CUSTOMERID   CHAR(2 BYTE),

  25                    36       3500     MAILING
  25                    39       2800     LEGAL

  Need a result like this:

  CUSTOMERID | MAILING_CITY | MAILING_ZIP | LEGAL_CITY | LEGAL_ZIP
  23                 41               3100          63        4720
  24                 44               3200          NULL     NULL
  25                 36               3500          39        2800

  Thank you very much
  Alex

  Try this...

  This works for me in Oracle 10 g.

  select customerid,
         MAX(DECODE(CONTACTTYPE,'MAILING',city,null)) MAILING_CITY,
         MAX(DECODE(CONTACTTYPE,'MAILING',zip,null)) MAILING_ZIP,
         MAX(DECODE(CONTACTTYPE,'LEGAL',city,null)) LEGAL_CITY,
         MAX(DECODE(CONTACTTYPE,'LEGAL',zip,null)) LEGAL_ZIP
  from test_data
  group by customerid

• Need for the sql query to have several columns in a single coulumn

  Hello

  You want a way to confirm that what looks like two rows is really a line?

  Here are three ways:

  (1) count the lines:

  WITH  my_original_querry     AS
  (
       select  a.customer_trx_id || CHR(13)
                        || a.previous_customer_trx_id     as id
       from      ra_customer_trx_all     a
       where      a.customer_trx_id      = 274881
  )
  SELECT     COUNT (*)
  FROM     my_original_query;
  

  (2) in SQL * Plus, have SQL * more count them for you:

  SET     FEEDBACK     1
  
  select  a.customer_trx_id || CHR(13)
                   || a.previous_customer_trx_id     as id
  from      ra_customer_trx_all     a
  where      a.customer_trx_id      = 274881;
  

  (3) implicitly count them with the ROWNUM Pseudo-column

  select  a.customer_trx_id || CHR(13)
                   || a.previous_customer_trx_id     as id
  ,     ROWNUM
  from      ra_customer_trx_all     a
  where      a.customer_trx_id      = 274881;

  /

  table should point to the table where the XML column is default, I guess that

  is the 'root' in the same line a reference to the name of the xmltype column?

  Now - how do I ensure the XML I have insert in the column "change" is validated against the schema above?

  concerning

  Mette

  
  

  For both options, save the diagram with these options (you can substitute the url of course):

  Start

  () dbms_xmlschema.registerSchema

  schemaURL-online "test.xsd.

  schemaDoc-online xmltype (bfilename ('TEST_DIR', 'test.xsd'), 873)

  local-online true

  genTypes-online fake

  genTables-online fake

  enableHierarchy-online dbms_xmlschema. ENABLE_HIERARCHY_NONE

  options-online dbms_xmlschema. REGISTER_BINARYXML

  );

  end;

  /

  Then the #1 option:

  create table root_table)

  Identification number

  text xmltype

  )

  XMLType column can store as xml binary securefile

  XmlSchema 'test.xsd' element 'root '.

  Both options will perform a validation of strict type.

  There are other possible configurations, such as CLOB based on a storage schema, but this approach is now obsolete.

  If you are only interested in whether the XML instance is valid or not, you can also use a constraint check with the XMLisValid function.

• Hide the results of the column in the total row large pivot

  Hello
  
  Do you know if it is possible to hide the result of a particular column in a total row large pivot?
  I have several columns that makes sense to use a total of lines (as in money), but others (like average) is not logical in view of the customer to business rules.
  
  Any help on this is much appreciated :)
  
  Thanks in advance,
  J marks

  Have you tried to move this column of lines measure?

• Transpose a single row of (definition, value) pairs in 2 columns

  I need to convert or turn a result monkey of a row in a table 2 (alias) manual column headers.

  Table

  ID	Description	Option1 Desc	value of option 1	Option 2 Desc	value of option 2	Option3 Desc	value of option3	Option4 Desc	Option4 value
  1	Seller - Lang - Menutype	Seller - Lang - Opt1	Value1	Seller - Lang - Opt2	Value2	Seller - Lang - Opt3	Value3	Seller - Lang - Opt4	Value4

  My current table has 8 options in total, but this should be enough.

  My select statement can make me what I want if poster horizontally that I missing just the knowledge necessary to transpose.

  Menu option	Value	Menu option	Value	Menu option	Value	Menu option	Value
  Seller - Lang - Opt1	Value1	Seller - Lang - Opt2	Value2	Seller - Lang - Opt3	Value3	Seller - Lang - Opt4	Value4

  I have to post this and I really need a query.

  Menu option	Value
  Seller - Lang - Opt1	Value1
  Seller - Lang - Opt2	Value2
  Seller - Lang - Opt3	Value3
  Seller - Lang - Opt4	Value4

  Hello

  It's called Unpivoting, and here's a way to do it:

  SELECT menu_option, value

  FROM table_x

  UNPIVOT (menu_option, value)

  COLLAR IN ((option1_desc, option1_value))

  (option2_desc, option2_value)

  (option3_desc, option3_value)

  (option4_desc, option4_value)

  )

  ;

  If you would care to CREATE States TABLE and INSERT post for your sample data, then I could test it.

• Column not null in rows in SQL query

  I have the below query,

  WITH t

  Did YOU (SELECT NULL col_1, col_2, 'C' FROM DUAL col_3 NULL

  UNION ALL

  SELECT 'A' col_1, col_2 NULL, NULL FROM DUAL col_3

  UNION ALL

  NULL SELECT col_1, col_2 "B", NULL FROM DUAL col_3)

  SELECT *.

  T;

  who will pick up three rows, on which single column will have a value for each row.
  And the other columns are left out as below.

  COL_1	COL_2	COL_3
  		C
  A
  	B

  I don't need that values should be extracted in the column name that is not null.

  as

  COL_1	COL_2	COL_3
  A	B	C

  
  Please advise me

  You can use the MAX aggregate function. But do not know what you are trying to reach.

• Single line based on two columns and a single column

  Dear members,
  
  I have a table that contains duplicate rows, for which a request should be able to extract the unique row in the table. Here the unique is not based on a single column, but it should be in two columns and also check on the uniqueness on a column.
  
  create table addr (varchar2 (10) firstname, lastname varchar2 (10), area varchar2 (3));
  
  insert into values addr ('bob', 'james', 1');
  insert into values addr ('bob', 'james', 1');
  
  insert into values addr ('harry', 'bert', ' 1');
  insert into values addr ('jimmy', 'bert', ' 1');
  
  insert into values addr ('sam', 'mac', '1');
  insert into values addr ('sam', 'Knight', '1');
  
  insert into values addr ('tom', 'sand', '1');
  insert into values addr ("cat", "mud", "1");
  
  
  The query output must contain 3 lines.
  
  Bob - james
  Harry - bert or jimmy - bert [or the other of them], but not both
  -Mac or sam - Sam Knight [or the other of them], but not both
  Tom - sand
  Cat - mud
  
  SELECT firstname, lastname as total area WHERE addr = '1' GROUP by firstname, lastname; It takes no duplication of single column...
  
  Any suggestions...

• Merge multiple columns into a single column?

  Hello
  
  I need to perform queries dynamically and the return values. I need to retrieve the values of the queries in a single column only by concatenating multiple columns. I can't use the PL/SQL in my scenario.
  is it possible to run a query and the result will be extracted in a single column (multiple column values must be concatenated)?
  
  Thank you
  Raja.
