transpose the data in the column to the line

I want to change the columns in lines, my data is

TYPERANK
1A
1AA
1AAA
2B
2BB

I want it in

RANK (1)RANK (2)
AB
AABB
AAA

Please help me

Thanks for the response guys, in the meantime, I found the solution too

SELECT MAX(CASE WHEN ID=1 THEN RATING ELSE NULL END) AS RC,

MAX(CASE WHEN ID=2 THEN RATING ELSE NULL END) LAUGHED

FROM (SELECT ID, RATING, ROW_NUMBER() over (ORDER BY rowid ID PARTITION) RN)

OF RANK_TEST) X

GROUP BY RN;

Thank you very much

  • Select the lines with the maximum value for a date where another column is different from 0

    Hello

    I need to write a query on a table (called DEPRECIATION) that returns only the rows whose date maximum (PERENDDAT_0 column) for a specific record (identified by AASREF_0), and where the other column in the table called DPRBAS_0 is different from 0.

    If DPRBAS_0 is equal to 0 in all the lines of a specific record, then return the line with date maximum (PERENDDAT_0 column).

    To be clearer, I give the following example:

    Suppose we have the following data in the table of DEPRECIATION:

    AASREF_0 PERENDDAT_0 DPRBAS_0
    I2011001074331/12/20150
    I2011001074331/12/20140
    I2011001074331/12/20130

    I2014001223831/12/2015445
    I2014001223831/12/20140

    The query must return only the following lines:

    AASREF_0 PERENDDAT_0 DPRBAS_0
    I2011001074331/12/20150
    I2011001085631/12/2014332

  • Transform the data in the column marked in lines

    I've already implemented Tom Kytes solution for dynamic / variant in the list that is found here and on his own works very well when passing a variable.  I'm trying to use it to decode several rows in a table.  Each row has a column of delimited data and I want to turn these data delimited by lines.

    Here is the configuration.

    create table data_source

    (upload_id number not null,

    data_source_id integer not null,

    sources varchar2 (50).

    ERROR_MESSAGE varchar2 (100)

    );

    insert into data_source (upload_id, data_source_id, sources) values (1, 1, 'a');

    insert into data_source (upload_id, data_source_id, sources) values (1,2, 'A:B:C:X');

    insert into data_source (upload_id, data_source_id, sources) values (1, 3, 'c');

    insert into data_source (upload_id, data_source_id, sources) values (1, 4, 'B');

    insert into data_source (upload_id, data_source_id, sources) values (1.5, 'Y');

    create the table data_source_lookup

    (varchar2 (10) sources non-null)

    ;

    insert into data_source_lookup (sources) values('A');

    insert into data_source_lookup (sources) values('B');

    insert into data_source_lookup (sources) values('C');

    My goal is to update the table data_source for lines where there is an invalid data source, in the example above that would be 2 and 5 lines.  I can do this individually using the in_list solution:

    Select * from table (in_list ('A:B:C:X',' :'))))

    If column_value not in (select data_source_lookup sources)

    Returns 'X' as expected.

    What I am struggling with is a method to make it through all the lines for a given loading ID:

    Update data_source

    ERROR_MESSAGE = "Source of data" is not a valid value

    where upload_id = 1 and...

    I tried to create a join cross- like this:

    Select ds.data_source_id, ds.sources, x.column_value

    DS data_source cross join (select column_value in the table (in_list (ds.sources,' :'))) x)))

    but as you can imagine passing in the function ds.sources has failed, returning "ORA-00904:"DS".» "SOURCES": invalid identifier.

    I'm sure I can solve this problem in a loop, but that seems inefficient.  Anyone know of a method by which I can pass the content of the column to the table function (in_list ()) for each line?

    For someone else it may call a function table in several lines, here's what I came with.  First of all, I changed my data to test a bit to add some very incorrect values.

    setting a day from sources set data_source = 'A:B:C:X:Y' where data_source_id = 1;

    This query will not return a list of lines that contain invalid values, including their wrong value:

    Select the rowid, sources, column_value

    de)

    Select the rowid, data_source sources)

    x cross table junction (utils.in_list (x.sources,' :'))))

    where column_value is not null

    and not exists (select null from data_source_lookup l where l.sources = column_value)

    AABk3MAAjAAAKd8AAA A:B:C:X:Y X

    AABk3MAAjAAAKd8AAA A:B:C:X:Y Y

    AABk3MAAjAAAKd8AAB A:B:C:X X

    AABk3MAAjAAAKd8AAE Y Y

    With this work, I can then modify cela a little bit to turn it back in a delimited list bad values that I can put in the error column.

    Update data_source x 2

    ERROR_MESSAGE = value

    (by selecting bad_value in)

    Select RID, "Invalid Data Source - ' |" listagg(column_value,':') within the Group (column_value control) bad_value

    de)

    Select the rowid RID, data_source sources)

    x cross table junction (utils.in_list (x.sources,' :'))))

    where column_value is not null

    and not exists (select null from data_source_lookup l where l.sources = column_value)

    (Group of RID) where rid = x 2 .rowid)

    where x 2 .upload_id = 1

    and x2.rowid in (select RID)

    de)

    Select the rowid RID, data_source sources)

    x cross table junction (utils.in_list (x.sources,' :'))))

    where column_value is not null

    and not exists (select null from data_source_lookup l where l.sources = column_value))

    ;

    It works well, and I find myself with:

    Error sources

    Source of invalid data in A:B:C:X:Y - x: y

    Invalid Data Source - X A:B:C:X

    C

    B

  • How to duplicate the data in a column?

    I have

    < code >

    Suggestions?

    TIA

    Hello

    If you want that each row of the result set to contain something that reflects the overall result (in this case, the value of the poles of the 1 row of the result set that's aname = "ccc"). This looks like a job for an analytic function.
    Here's one way:

    WITH     sample_data     AS
(
     SELECT '1' DFILE
     ,'aaa' ANAME
     ,'no' ahelp
     FROM DUAL
     UNION
     SELECT '1' DFILE
     ,'bbb' ANAME
     ,'no' AHELP
     FROM DUAL
     UNION
     SELECT '0' DFILE
     ,'ccc' ANAME
     ,'yes' AHELP
     FROM DUAL
)
SELECT     dfile
,     aname
,     MIN (CASE WHEN aname = 'ccc' THEN ahelp END)
             OVER ()                      AS ccc_ahelp
FROM     sample_data
;

    What results would you if the result set does not contain a line with aname = "ccc"? The query above would have NULL in the last column.
    What if there were 2 (or more) lines with aname = "ccc"? The query above takes the first value (in the normal sort order) of the lines with aname = "ccc". If they are all lucky to have the same value of poles, then, of course, this will be the first.

    display the data in row columns
     
			 I looked through the previous posts, but it is impossible to find a solution to my problem.
    

    I want to display the data in row columns.
    I have shown in the table below and test data and the sql code that gives me the result desired.
    However, you can see that the sql depends of me knowing all the values in the column "rank".
    I want a way to produce the output without knowing the values of rank.
    


    CREATE TABLE test1 (
  accno       NUMBER,
  holder_type VARCHAR2(10),
  rank        NUMBER)

INSERT INTO test1 VALUES (1, 'acr', 0);
INSERT INTO test1 VALUES (1, 'bws', 1);
INSERT INTO test1 VALUES (1, 'aaa', 2);
INSERT INTO test1 VALUES (2, 'cds', 0);
INSERT INTO test1 VALUES (2, 'xxx', 1);
INSERT INTO test1 VALUES (3, 'fgc', 0);
INSERT INTO test1 VALUES (4, 'hgv', 0);
INSERT INTO test1 VALUES (4, 'bws', 1);
INSERT INTO test1 VALUES (4, 'qas', 2);
INSERT INTO test1 VALUES (4, 'aws', 3);

Here's the required output:=
ACCNO     ALLCODES
1     acr bws aaa
2     cds xxx
3     fgc
4     hgv bws qas aws

I.E. for each accno display the holder_types in rank sequence.

SELECT * FROM
(SELECT 
       a0.accno,
       a0.holder_type || DECODE(a1.holder_type, NULL, NULL, ' ') ||
       a1.holder_type || DECODE(a2.holder_type, NULL, NULL, ' ') ||
       a2.holder_type || DECODE(a3.holder_type, NULL, NULL, ' ') ||
       a3.holder_type || DECODE(a4.holder_type, NULL, NULL, ' ') ||
       a4.holder_type allcodes
  FROM (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 0) a0,
       (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 1) a1,
       (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 2) a2,
       (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 3) a3,
       (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 4) a4
 WHERE a0.accno = a1.accno(+)
   AND a0.accno = a2.accno(+)
   AND a0.accno = a3.accno(+)
   AND a0.accno = a4.accno(+)) a

FROM CASEDTL CD
    INNER JOIN CASEMSTR CM
        ON CD.CASENBR = CM.CASENBR;
    Need to know what is the best way to complete the new Date of RRS? Receive a new date should be the minimum date of DATEISSUED, DATEPLACED, DATEENTERED and STATDATE. And also how do I write an update statement unique to upade date of receipt in the detail table?

    There is no problem with the index of line-1, as long as you read one column.
    

    To read several columns, you must set the start and the end of the table block. Since you know your number in the column, simply determine the line number. You can use the Row.vi last Excel get, as shown below.

    Unless you tell it otherwise, SQL * Loader assumes that each later in the table and what clause after the first back in the position where the previous left off.  If you want to start at the beginning of the line every time, then you need to reset the position using position (1) with the first column, as shown below.  Position on the first using is optional.

    Divide the line into several columns
     
			 
    Hi all
    I have a question where I want to divide the line into multiple columns based on the delimiter ' |'.
    Staging of Table structure: People_STG, I have people in it.
    Create table People_STG(col1 varchar2(4000));

    Insert into People_STG(Emp_id|) User name | FirstName. LastName. JobTitle | hire_date | Location_id)

    SELECT REGEXP_SUBSTR ( COL1, '[^,|]+', 1, 1) EMP_ID,
       REGEXP_SUBSTR ( COL1, '[^|]+', 1, 2) USERNAME,
       REGEXP_SUBSTR ( COL1, '[^,|]+', 1, 3) FIRSTNAME,
       REGEXP_SUBSTR ( COL1, '[^,|]+', 1, 4) LASTNAME,
       REGEXP_SUBSTR ( COL1, '[^,|]+', 1, 5) JOBTITLE,
       REGEXP_SUBSTR ( COL1, '[^,|]+', 1, 6) HIRE_DATE,
       REGEXP_SUBSTR ( COL1, '[^,|]+', 1, 7) LOCATION_ID
FROM PEOPLE_STG
WHERE length(regexp_replace(COL1, '[^|]', '')) = 14;

    But I am facing a problem here, as in some lines, function is null, but when I run the above query, it is not recognizing the empty element and inserting Hire_date values of function and location_id in Hire_date where function is null.
    for example: 1 | akash51 | Akaksh | C | 22/11/14 | 15
    Here the function is null, so when I run top to divide query it will insert 11/22/14 in the function column and 15 in Hire_Date.
    Please need help on this one.
    Oracle Version: 11.2 g
    Thanks in advance,

    A statement UPDATE changes the line if the update changes the column even value?
     
			 
    HI -.
    I have a main classification and the corresponding audit table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211
    Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time. He is not able to determine that the value is the same.
    My goal is to load the audit table data if the value in a cell in the main table is really have changed.
    A statement UPDATE changes the line if the update changes the column even value?
    Best regards
    			 
    I have a main Table and the corresponding Audit Table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211
    

    Why?
    

    You try to resolve what made you what are the PROBLEM that select as the solution?
    

    Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time.
    

    Yes - it is EXACTLY what you say that you wanted to do and EXACTLY what the code does in this article.
    

    He is not able to determine that the value is the same.
    

    I think you mean that the code does NOT check if the value is the same. You can certainly change the code to do this check. But I have a question to start with your need for such a solution.
    

    My goal is to load the audit table data if the value in a cell in the main table is really have changed.
    

    OK - then modify the code to check EACH COLUMN and compare its NEW value to the OLD value and insert only the table of audit if SOME (or columns you care specifically) have changed.
    

    A statement UPDATE changes the line if the update changes the column even value?
    

    It depends on what you mean by 'change the line '. Of course to update a column with the SAME value does not change the resulting data value.
    

    But the physical structure of the line, the location of the pieces of line and information in the header block (YVERT, etc.) will change. And, as others have said Oracle doesn't know and doesn't care, so if the new value of a column is the same as the old value will create redo, undo and the rest.
    

    Start over and tell us what PROBLEM you're trying to solve. Then we can help you find the best way to solve it.

    Error: The lines of data with unmapped dimensions exist for period "1 April 2014".
     
			 
    Expert Hi
    The below error when I click on the button Execute in order to load data in the area of data loading in 11.1.2.3 workspace. Actually, I already put in the tabs global mapping (add records of 12 months), mapping of Application (add records of 12 months) and map sources (add a month "1 April 2014' as the name of period with Type = Explicit mapping") in the service of the period mapping. What else should I check to fix this? Thank you.

    Thanks to all you guys
    

    This problem is solved after I maped all dimensions in order of loading the data. I traced only Entity, account, Custom1 and Custom2 at first because there is no source map Custom3, Custom4 and PIC. After doing the mapping for Custom3, Custom4 and PKI, the problem is resolved. This is why all dimensions should be mapped here.

    How remove the line by line by comparing to the first column?
     
			 Hello!
    

    I have a problem - I need to remove the line by line, but the problem is, I know that the first COLUMN of the table is a PK.
    To retrieve the NAME of the COLUMN that I use:
    

    SELECT column_name, table_name FROM USER_TAB_COLUMNS WHERE column_id = 1 and table_name = c1.tmp_table_name;
    But it does not somehow.
    Below you can see my script (which has not worked for now):
    

    declare
    XXX varchar2 (100);
    Start
    C1 in (select table_name, tmp_tables tmp_table_name) loop
    IMMEDIATE EXECUTION
    ' SELECT column_name in ' | xxx | "USER_TAB_COLUMNS WHERE column_id = 1 AND table_name = ' |" ' || C1.tmp_table_name | " ' ;
    immediate execution
    "start."
    for c2 in (select * from ' | c1.tmp_table_name | start loop ')
    Insert into ' | C1.table_name | "values c2; delete from ' | C1.tmp_table_name | 'where ' | xxx |' = c2.' | xxx |'; exception: when other then null; end; end loop; end;';
    end loop;
    end;
    

    P.S. The Inserts work perfect. I have a problem with deleting lines that are in c1.table_name, of c1.tmp_table_name (the two tables have the same structure, PK, always), because I have the names of columns different another tables which are PK. (for example: K, ID, NS and so on) Please help me to write the correct script.
    For example this will be for the first line recovered as:
    Start
    C1 in (select table_name, tmp_tables tmp_table_name) loop
    immediate execution
    «Start for c2 in (select * from ' |)» C1.tmp_table_name | Start loop ')
    Insert into ' | C1.table_name | "values c2; delete from ' | C1.tmp_table_name: ' where K = c2. K; exception: when other then null; end; end loop; end;';
    end loop;
    end;
    This script works perfectly. But I have many other tables with different PK - K No.

    Need help for the conversion of the lines in columns
     
			 Hi all
    

    I have a table with 2 columns.
    colId value
    1 aaa
    2 bbb
    3 ccc
    1 ddd
    Eee 2
    3 fff
    

    I want to store the data in the table above in another table that has 3 columns.
    col1 col2 col3
    AAA bbb ccc
    DDD eee fff
    

    I am pivot query. But I don't get it properly. Help, please.
    

    I have Oracle Database 11 g Enterprise Edition Release 11.1.0.6.0 - 64 bit Production
    

    Thanks in advance,
    Girish G

    Hey Tubby,
    

    Let me explain the real-world scenario.
    

    I'm the external source CLOB data in oracle stored procedure.
    

    The data are coming in the form below.
    

    col1 # | #col2 # | #col3 ~ | ~ col1 # | #col2 # | #col3 ~ | ~ col1 # | #col2 # | #col3
    

    # Here. #-> is the column delimiter.
    and ~ | ~-> is the line delimiter.
    

    I want to store these data in a table that has 3 columns.
    

    My approach was to extract the data for each column and store it in a temporary table in separate lines. Then move the data from the temporary table to the destination table.
    

    Are there other alternatives for my requirement? Please suggest.
    

    Thank you
    Girish G
    

    Much better when you show us the context like that.
    

    It's late and I have sleepiness in my bones, so it's not likely optimal.
    

    select
   regexp_substr(split, '[^@]+', 1, 1) as col1 ,
   regexp_substr(split, '[^@]+', 1, 2) as col2 ,
   regexp_substr(split, '[^@]+', 1, 3) as col3
from
(
   select
      replace(regexp_substr(source_str, '[^@]+', 1, level), '#|#', '@') as split
   from
   (
      select
         replace('val1#|#val2#|#val3~|~val4#|#val5#|#val6~|~val7#|#val8#|#val9', '~|~', '@') as source_str
      from dual
   )
   connect by level <= length(source_str) - length (replace(source_str, '@') )  + 1
);

    

    I do not have an instance running (tested on XE) 11 so I can't use "magical" things like regexp_count and fun stuff. This should give you a basic idea of how to analyze data well.
    

    I decode your delimiters in something "more manageable" just because it's easier than worrying about the escaping of special characters and all that fun stuff I'm too asleep to try.
    

    Since you are dealing with a CLOB (you actually over 4,000 characters of data?) you have to give it up and look for a function in the pipeline as a suitable alternative.

    Conversion of column to the lines
     
			 Hello
    I'm currently building and SQL to convert columns from several lines to all lines - see below the test data and the expected result:
    CREATE TABLE XX_TEST (NAME VARCHAR2 (10), A1 VARCHAR2 (10), A2 VARCHAR2 (10), A3 VARCHAR2 (10), A4 VARCHAR2 (10), A5 VARCHAR2 (10));
    INSERT INTO XX_TEST VALUES('LIST','A','B','C','D','E');
    INSERT INTO XX_TEST VALUES('L1','1',,'3',,);
    INSERT INTO XX_TEST VALUES('L2','1','5','4',,);
    ENGAGE
    SELECT * FROM XX_TEST;
    

    Expected result:
    NAME is the table XX_TEST column, but the COLUMN and the VALUE are converted to lines - columns
    

    NAME THE COLUMN VALUE
    L1 A1 1
    L1 A2 NULL
    L1 A3 3
    L1 A4 NULL
    L1 A5 NULL
    L2 A1 1
    L2 A2 5
    L2 A3 4
    L2 NULL A4
    L2 A5 NULL
    

    Thank you

    Don't foget Aketi!
    

    The two ways are really good and functional in my situation.
    I apologize for not giving version: I'm on 11g so I think that can use Unpivot. It would be really more faster (performance given the volume of data) to use unpivot characteristic of 11 g?
    

    If there is no significant difference, whereas I think is that SELECT... UNPIVOT would be faster. It is purely a guess. It depends on several factors, including your data, your index and your machine. I don't have access to one of them.
    

    Try both ways and compare performance. (Compare the results, too, to check that the two qiueries are really doing the same thing).
    If you need help, see this thread:
    
HOW to: Validate a query of SQL statement tuning - model showing
    

    I've never used before unpivot.
    

    This sounds like a good opportunity to learn.
