Hello

How to split a string and store in an associative array in pl/sql.function

My string like this

You can try the following. Although I recommend, it would be better to write the function code php as a java stored procedure parser and use the result. We have a class defined in Java String Tokenizer.

-- Define function to split string into tokens
FUNCTION get_token(
    p_input_string IN VARCHAR2,            -- input string
    p_token_number IN PLS_INTEGER,         -- token number
    p_delimiter    IN VARCHAR2 DEFAULT ',' -- separator character
  )
  RETURN VARCHAR2
IS
  v_temp_string VARCHAR2(32767) := p_delimiter || p_input_string ;
  v_pos1 PLS_INTEGER ;
  v_pos2 PLS_INTEGER ;
BEGIN
  v_pos1     := INSTR( v_temp_string, p_delimiter, 1, p_token_number ) ;
  IF v_pos1   > 0 THEN
    v_pos2   := INSTR( v_temp_string, p_delimiter, 1, p_token_number + 1) ;
    IF v_pos2 = 0 THEN
      v_pos2 := LENGTH( v_temp_string ) + 1 ;
    END IF ;
    RETURN( SUBSTR( v_temp_string, v_pos1+1, v_pos2 - v_pos1-1 ) ) ;
  ELSE
    RETURN NULL ;
  END IF ;
EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END get_token;

-- Call the above function in loop for a string with N tokens
DECLARE
      TYPE assoc_arr_str_typ IS TABLE OF VARCHAR2(100) INDEX BY PLS_INTEGER;
      str_arr assoc_arr_str_typ;

      v_str VARCHAR2(200) := '1102,1101,1012,1011,1010,1009,1008,1007,1006,10005,1004,1003,1002,1001' ;

  • How to split a string into several substrings parent using a delimiter

    Hello

    I am forced to split a string into several substrings parent using a delimiter.

    And insert these substrings in variuou of the columns of a table in a row.

    For example. The sting is: ABC * DEF * GHI * JKH *.

    where ' *' is the separator.

    Desired output:

    Col1 Col2 Col3 Col4 Col5

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

    JKH GHI ABC DEF (null)

    Could you please guide me how can I achieve this.

    Thank you

    Hello Salim,

    Leave the thread for reference... got this excerpt:

    with t as

    (

    Select "c: its: hgfd:1:23" Str

    )

    Select

    REGEXP_SUBSTR (str, ' ([^:] *)(:|$)', 1, 1, null, 1) col1

    , REGEXP_SUBSTR (str, ' ([^:] *)(:|$)', 1, 2, null, 1) col2

    , REGEXP_SUBSTR (str, ' ([^:] *)(:|$)', 1, 3, null, 1) col3

    , REGEXP_SUBSTR (str, ' ([^:] *)(:|$)', 1, 5, null, 1) col5

    t;

    This code snippet works well, but for the fixed columns. Here are 5 predefined columns.

    But I need to have a logic that I can browse the string any No.. sometimes.

    For example. If I get 3 secondary channels of the parent chain... I need to insert into 3 columns.

    And if I get 6 strings under... I need to insert into 6 columns.

    Could you please help me develop a logic like that.

    I use Oracle database 10g.

    And the data are currently being collected on external table... but I can store in a variable or a column of a database table.

    Thank you

  • SQL / PLSQL to split the string into pieces

    Hi all

    I have a problem of data conversion from the name of one table to another structure.

    for example

    SQL > desc names
    Name Null? Type
    ----------------------------------------- -------- ----------------------------
    TITLE VARCHAR2 (5)
    FNAME VARCHAR2 (20)
    LNAME VARCHAR2 (20)

    SQL > Data desc
    Name Null? Type
    ----------------------------------------- -------- ----------------------------
    FULLNAME VARCHAR2 (50)


    Insert in data values ("SIR I HAVE ONE NAME PARTICULARLY LONG INDEED");
    Insert in the data values ("MINE IS EVEN MORE, ENOUGH RIDICULEMENT so IN FACT");

    Essentially, I need to divide these names long, stored in the 1 field, in the above 3 fields. The trickiest part is however I want to do it in such a way so that if the 1st part of the name fits the 1 5 char field I want to do, otherwise I would divide between 2 fields - once again without splitting a string. The reason behind this is that application will automatically put a space between each field when they appear and I would avoid gaps in the names if possible.

    This baffled me a little if any help would be seriously great... it might not even be a go-er, as it might be too uneconomic with the amount of available space, but I would give it a shot.

    Thank you!

  • Splits the string into two columns

    Can someone please help me the following

    I want to divide into two columns URL and ID /cfd/abc.html,/night/aaa/Page1,/can/MLP/Page2|107

    Result must be

    Temporary table
    < font color = "red" > URL < / police > < font color = 'blue' > ID < / make >

    < font color = "red" > /cfd/abc.html < / police > < font color = "blue" > 107 < / make >

    < font color = "red" > / night/aaa/page 1 < / police > < font color = "blue" > 107 < / make >

    < font color = "red" > / can/MLP/Page2 < / police > < font color = "blue" > 107 < / make >


    There can be N number of comma separated URLs, but there will be only 1 separate ID which is the vertical bar (|)

    Try this,

    SQL> WITH T
  2       AS (SELECT  '/cfd/abc.html,/night/aaa/Page1,/can/MLP/Page2|107 ' str FROM DUAL UNION ALL
  3           SELECT  '/cfd/def.html,/bbbb/bbbb/Page1,/lll/MLP/Page3|108 ' str FROM DUAL)
  4  SELECT REGEXP_SUBSTR ( str, '[^,|]+', 1, lvl) URL,
  5         REGEXP_SUBSTR ( str, '[^|]+', 1, 2) ID
  6    FROM T,
  7         (SELECT LEVEL lvl
  8            FROM (SELECT MAX (LENGTH (REGEXP_REPLACE ( str, '[^,]'))) mx FROM T)
  9          CONNECT BY LEVEL <= mx + 1)
 10   WHERE Lvl - 1 <= LENGTH (REGEXP_REPLACE ( str, '[^,]+'))
 11   order by id,lvl;

  • Splits the string into two columns to dashboard

    Hi all

    I got thisworking

    decode (SUBSTR (ADDR2_ATTR_1, 1, INSTR(ADDR2_ATTR_1,'-')-1), '9999', NULL, (SUBSTR (ADDR2_ATTR_1, 1, INSTR(ADDR2_ATTR_1,'-')-1))),

    decode (SUBSTR (ADDR2_ATTR_1, INSTR (ADDR2_ATTR_1,'-') + 1), '9999', NULL, (SUBSTR (ADDR2_ATTR_1, INSTR(ADDR2_ATTR_1,'-') + 1)))

    but the results were a little different.

    It came as

    Col1 for 8-10 have come beauiful... .but however Col2 data should be in K1 and transferred to Col2

    Col1 Col2
    < null > 10
    < null > 33
    8 10

    Any guidance is appreciated.

    Personally, I like the cases, but another way using the DECODE method...

    WITH t AS
        (SELECT '8-10' str FROM DUAL
         UNION ALL
         SELECT '163' FROM DUAL
         UNION ALL
         SELECT '789' FROM DUAL)
SELECT str col1,
       DECODE (NVL2 (NULLIF (INSTR (str, '-'), 0), 99999, 0),99999, SUBSTR (str, 1, INSTR (str, '-', 1) - 1),str) col2,
       DECODE (NVL2 (NULLIF (INSTR (str, '-'), 0), 99999, 0),99999, SUBSTR (str, INSTR (str, '-', 1) + 1),NULL) col3
  FROM t;

    Simplified:
    ------

    WITH t AS
        (SELECT '8-10' str FROM DUAL
         UNION ALL
         SELECT '163' FROM DUAL
         UNION ALL
         SELECT '789' FROM DUAL)
SELECT str col1,
       DECODE (SIGN (INSTR (str, '-')),1, SUBSTR (str, 1, INSTR (str, '-', 1) - 1),str)  col2,
       DECODE (SIGN (INSTR (str, '-')),1, SUBSTR (str, INSTR (str, '-', 1) + 1), NULL) col3
  FROM t;

    OUTPUT:

    COL1     COL2     COL3
8-10     8     10
163     163
789     789

    See you soon,.

    You are right that I excluded NULL, 8 rows out put to our example looks correct to me

    The result included "two" because its locked up in one of our separators

  • Simple question: how to divide the string into multiple lines concatenated?

    Hi people,

    Maybe it's an easy question.

    How to split a string that is concatenated into multiple lines by using the SQL query?

    ENTRY:
    select 'AAA,BBB,CC,DDDD' as data from dual
    Delimiter = ', '.

    Expected results:
    data
------------
AAA
BBB
CCC
DDDD
    I'm looking for something nice to feature "an opposite to «sys_connect_by_path»»

    Thank you

    with t as (select 'aaaa,,bbbb,cccc,dddd,eeee,ffff' as txt from dual)
-- end of sample data
select REGEXP_SUBSTR (txt, '[^,]+', 1, level)
from t
connect by level <= length(regexp_replace(txt,'[^,]*'))+1

REGEXP_SUBSTR(TXT,'[^,]+',1,LE
------------------------------
aaaa
