Separated by commas as columns

The text below table can values separated by commas and want to divide it into parts and display them as different columns.

For example

Output.jpg

I'm able to do with the CASE statement, but I was wondering if it can be done in a different way.

CREATE TABLE T)

ID NUMBER 4,

TEXT VARCHAR2 (100)

);

INSERT INTO T VALUES (1, 'ALL, biased');

INSERT INTO T VALUES (2, 'ALL, Zero');

INSERT INTO T VALUES (3, 'STAT, NOSTAT');

INSERT INTO T values (4, 'ONEVALUE');

SELECT id, text,

CASE WHEN INSTR (text, ',') > 0 THEN

SUBSTR (text, 1, (INSTR(text,',')-1))

ON THE OTHER

TEXT

END part_1

CASE WHEN INSTR (text, ',') > 0 THEN

SUBSTR (text, INSTR (text, ",") + 1, LENGTH (text))

ON THE OTHER

NULL VALUE

END Part_2

T;

Here's one way:

WITH got_comma_pos AS

(

SELECT id, text

, INSTR (text |) ','

, ','

) AS comma_pos

T

)

SELECT id, text

, SUBSTR (text, 1, comma_pos - 1) AS part_1

SUBSTR (text, comma_pos + 1) AS part_2

OF got_comma_pos

ORDER BY id

;

You can also use regular expressions, but it will be slower.

    Hello

    Use REGEXP_SUBSTR:

    SELECT  REGEXP_SUBSTR (str, '[^,]+', 1, 1)    AS part_1
    ,       REGEXP_SUBSTR (str, '[^,]+', 1, 2)    AS part_2

    FROM    table_x
    ;
    

    Str can contain foul? For example, you can have a string like ' foo, bar ", where you want to count part_2 and part_3 as NULL and 'bar' is part_4? If so:

    SELECT  RTRIM (REGEXP_SUBSTR (str, '[^,]*,', 1, 1), ',')    AS part_1
    ,       RTRIM (REGEXP_SUBSTR (str, '[^,]*,', 1, 2), ',')    AS part_2
    ,       RTRIM (REGEXP_SUBSTR (str, '[^,]*,', 1, 3), ',')    AS part_3
    ,       LTRIM (REGEXP_SUBSTR (str, ',[^,]*', 1, 3), ',')    AS part_4

    I have to write a procedure like this

    So sys_refcursor structure will be

    Open the p_pcur for

    I must get the id separated by commas of column bone and lang and map to the corresponding table to get the names separated by commas of the bones and langs and pass it as a component of sys_refcursor.

    Open the p_ccur for

    Select * from a_os_lang_stls

    where swb_number = p_sb_no

    Could someone please help me how to convert the value separated by commas in a comma separated value new map to another table and pass it as part of the sys_refcursor.

  • Value separated by commas in a table column to get each field separtely?

    Hello

    I have the table that a column has values separated by commas in it. This table is populated using SQL LOADER, which is staging table.

    I need to retrieve the records of these values separated by commas.

    format of. CSV file is as -

    A separate file of pipes.

    DHCP-1-1-5 | WNLB-CMTS-02-2,WNLB-CMTS-04-4,WNLB-CMTS-05-7|

    CREATE TABLE link_data (dhcp_token VARCHAR2 (30), cmts_to_add VARCHAR2 (200), cmts_to_remove VARCHAR2 (200));

    insert into link_data values ('dhcp-1-1-1','wnlb-cmts-01-1,wnlb-cmts-02-2',null);

    insert into link_data values ('dhcp-1-1-2','wnlb-cmts-03-3,wnlb-cmts-04-4,wnlb-cmts-05-5',null);

    insert into link_data values ('dhcp-1-1-5','wnlb-cmts-02-2,wnlb-cmts-04-4,wnlb-cmts-05-7',null);

    Here the cmts_to_add column has comma separted

    I need values such as -.

    > for wnlb-cmts-01-1,wnlb-cmts-02-2 > > wnlb-CMTS-01-1

    > > wnlb-CMTS-02-2

    > > wnlb-CMTS-04-4

    > > wnlb-CMTS-05-5

    And so on...

    I do this because it's the staging table and I load data into the main tables using this table.

    This second field contain different values as the simple comma-delimited string.

    I need to write a PLSQL block to insert into the main table after checking as if dhcp-1-1-1 and wnlb-CMTS-01-1 is present in the main table so not to introduce other insert a new record.

    To meet this requirement, I need to get the distinct value of the cmts_to_add column to insert into DB.

    the value will be inserted as dhcp-1-1-1_TO_wnlb-cmts-01-1 and dhcp-1-1-1_TO_wnlb-cmts-02-2 for the first row of the array of link_data.

    The process will also be same for the rest of the lines.

    I use the function substrt and instr for this problem, but its does not work.

    declare

    cursor c_link is select * from link_data.

    l_rec_link link_data % rowtype;

    l_dhcp varchar2 (30);

    l_cmts varchar2 (20000);

    l_cmts_1 varchar2 (32000);

    Start

    Open c_link;

    loop

    extract the c_link in l_rec_link;

    l_cmts: = l_rec_link.cmts_to_add;

    loop

    l_cmts_1: = substr (l_cmts, 1, instr(l_cmts,',')-1);

    dbms_output.put_line (l_cmts_1);

    end loop;

    dbms_output.put_line(l_dhcp||) e '|| l_cmts);

    When the output c_link % notfound;

    end loop;

    exception

    while others then

    Dbms_output.put_line ('ERROR' |) SQLERRM);

    end;

    Its a peusdo code I write, but it also gives me the wrong answer it gives me error ORA-20000: ORU-10027: buffer overflow, limit of 20000 bytes

  • How to recover the vales separated by commas in the same column in Oracle SQL

    Dear members

    Please give me the solution for the below question

    Oracle table

    Ename product
    A 1,2,3
    B 1,2,3


    Product column has data like this only separated by commas

    Output should be like this.

    Ename, product
    A 1
    A 2
    A 3
    B 1
    B 2
    B 3

    Can we get the output above using just Oracle SQL select statement?
    I tried in Google I got an answer in SQL server, there is something called "Cross apply split" function, I'm not sure in Oracle.

    Welcome to the forum.

    Here is another interesting site, with lots of useful examples:

    I've got a column of values:

  • the list of columns separated by commas of a dictionary table table

    I use the following question.

    CONNECT_BY_ROOT SELECT table_name TopLevel, level,
    connect_by_isleaf IS_Node_leaf,
    substr (SYS_CONNECT_BY_PATH (column_name, ','), 2) column_name
    Of all_tab_cols
    where connect_by_isleaf = 1
    and column_id < (select max (column_id) + 1 all_tab_cols
    where table_name = 'Table_test')
    and column_id > (select min (column_id) - all_tab_cols 1
    where table_name = 'Table_test')
    START WITH table_name = "Table_test."
    CONNECT BY PRIOR column_id = nocycle (column_id - 1).
    AND table_name = "Table_test."

    The only problem with this query is that it goes into infinite loop. Can someone suggest a better solution?

    Why you ask all_tab_cols, I think will realize you that it will pull all tables in your database.

    If you want to retrieve the name of the table and the columns (separated by commas) your schema, you must query user_tab_cols.

    and here is the sql code

    select table_name,ltrim(sys_Connect_by_path(column_name,','),',') column_names
    from
    (select table_name,column_name,row_number() over (partition by table_name order by column_id) rn
    from user_tab_cols)
    where connect_by_isleaf = 1
    start with rn=1
    connect by prior rn=rn-1 and prior table_name = table_name
    /
    

    Or, you can use all_tab_cols to query a specific table by passing the name of the table and the name of the owner

    where connect_by_isleaf = 1

  • How to search for a particular text values separated by commas

    Hello

    I have a table for example. TB_Fruits.
    In that I have a FruitsName (Varchar) column
    In this column I store the string of values separated by commas.
    Select FruitsName in the tb_fruits;
    Result: orange, banana, Apple

    Now the question is suppose that if I try inserting one of these fruits once again name, then it must not allow me to insert.

    Suppose that now if I try to insert ('grapes, banana')
    or
    (Apple, grape")

    the orange, banana, Apple may be in any position.

    How to check if one of these names exist already or not in the fruitsname column?
    I can't use INstr function here as or. because the position is not fixed chain even not.

    Appreciate any help.

    Hmm, OK, the BASIC_LEXER in the documentation is specified is useful to "spaces separate languages". So not really a good suggestion from my side ;-)

    Okay, so a few different choices, you can play with:

    SQL> create table tb_fruits (
      2     fruitsname  varchar2(60)
      3  )
      4  /
    
    Table created.
    
    SQL> begin
      2     insert into tb_fruits values ('BANANA,APPLE');
      3     insert into tb_fruits values ('YELLOW BANANA,ORANGE');
      4     insert into tb_fruits values ('GREEN APPLE,YELLOW ORANGE');
      5     insert into tb_fruits values ('APPLE,GREEN BANANA');
      6     commit;
      7  end;
      8  /
    
    PL/SQL procedure successfully completed.
    

    Option 1:

    Make a outdated AS operator. It just won't be fast because it's more likely will be full table scan (or scan restricted index full).

    SQL> select fruitsname
      2    from tb_fruits
      3   where ','||fruitsname||',' like '%,'||'APPLE'||',%'
      4  /
    
    FRUITSNAME
    ------------------------------------------------------------
    BANANA,APPLE
    APPLE,GREEN BANANA
    
    SQL> select fruitsname
      2    from tb_fruits
      3   where ','||fruitsname||',' like '%,'||'BANANA'||',%'
      4  /
    
    FRUITSNAME
    ------------------------------------------------------------
    BANANA,APPLE
    
    SQL> select fruitsname
      2    from tb_fruits
      3   where ','||fruitsname||',' like '%,'||'YELLOW BANANA'||',%'
      4  /
    
    FRUITSNAME
    ------------------------------------------------------------
    YELLOW BANANA,ORANGE
    

    Option 2:

    Transform your data and replace the spaces with underscores. Which may or may not be a possibility for you. If your other data contains no underscores, you might fool your user interface using a view that replaces underscores with spaces when you select and a trigger before insert that replaces spaces with underscores to insert or update. Then, you can use the TEXT index.

    SQL> create table tb_fruits2 as
      2  select replace(fruitsname,' ','_') fruitsname
      3    from tb_fruits
      4  /
    
    Table created.
    
    SQL> begin
      2     ctx_ddl.create_preference('mylex', 'BASIC_LEXER');
      3     ctx_ddl.set_attribute('mylex', 'printjoins', '_-');
      4  end;
      5  /
    
    PL/SQL procedure successfully completed.
    
    SQL> create index fruitsname_idx on tb_fruits2 (fruitsname)
      2  indextype is ctxsys.ctxcat
      3  parameters (
      4  'stoplist ctxsys.empty_stoplist
      5  LEXER mylex'
      6  )
      7  /
    
    Index created.
    
    SQL> select fruitsname
      2    from tb_fruits2
      3   where catsearch(fruitsname,replace('YELLOW BANANA',' ','_'),null) > 0
      4  /
    
    FRUITSNAME
    ------------------------------------------------------------
    YELLOW_BANANA,ORANGE
    

    (I used CTXCAT rather then CONTEXT indexes to keep simple search syntax, avoid SYNCHRONIZATION problems and others. You can use CONTEXT or CTXCAT as desired.)

    Option 3:

    Transform your data in XML format instead of values separated by commas. Then create a XMLIndex.

    SQL> create table tb_fruits3 as
      2  select xmltype(''||replace(fruitsname,',','')||'') fruitsname
      3    from tb_fruits
      4  /
    
    Table created.
    
    SQL> create index fruitsname_xmlidx on tb_fruits3 (fruitsname)
      2  indextype is xdb.xmlindex
      3  /
    
    Index created.
    
    SQL> select fruitsname
      2    from tb_fruits3
      3   where xmlexists('$f/l[w="YELLOW BANANA"]' passing fruitsname as "f")
      4  /
    
    FRUITSNAME
    --------------------------------------------------------------------------------
    YELLOW BANANAORANGE
    

    (I used just 'l' for 'list of the words' and 'w' for 'word').

    Option 4:

    Create your own [url http://docs.oracle.com/cd/E11882_01/text.112/e24436/cdatadic.htm#i1008347] USER_LEXER instead of a variant of BASIC_LEXER. This would require allows you to create your own stored procedures for the index to be used, in which case you have complete control over what you set in the form of a token.

    That's the different options I can think of right now ;-)
