have a doubt while spool the records from a table to csv i had a problem,

actually my requirement is when we use the colsep it places the each data to each cell of the excel,but in some cases in table one column values are inserted as

for example column address has the value

address1,address2....etc in this case the column delimited values will be placed in the next cells,ie means one column has placed in multiple cells,

so the issue is.. in that case how to place each column value in each cell..?

please find the following i used

SET ECHO OFF VERIFY OFF PAGESIZE 0 TERMOUT OFF TRIMSPOOL OFF LINESIZE 6000 COLSEP ','

SPOOL /appl/noa/abinitio/sample.csv

select ,,,,,,,,,,,,,,,,,,,query

SPOOL OFF

SET TERMOUT ON

can u please send me a reply as soon as possible...?

Thanks in advance

If a column contains commas, and you want that value to occupy only a single column in your CSV file, then surround it with double quotes.
----------------------------------------------------------------------
SQL> CREATE TABLE t (text VARCHAR2(15), more_text VARCHAR2(15));
 
Table created.
 
SQL> INSERT INTO t VALUES ('ok','also ok');
SQL> INSERT INTO t VALUES ('1,2,3','still no commas');
SQL> INSERT INTO t VALUES ('comma-free','so, now what?');
SQL> INSERT INTO t VALUES ('8,9,10',',11,12,13');
SQL> SELECT t.text
  2  ,      t.more_text
  3  FROM   t
  4  /
 
TEXT            MORE_TEXT
--------------- ---------------
ok              also ok
1,2,3           still no commas
comma-free      so, now what?
8,9,10          ,11,12,13
 
SQL> SELECT DECODE(INSTR(t.text,',')
  2         ,      0, t.text
  3         ,      '"' || t.text || '"')      text
  4  ,      DECODE(INSTR(t.more_text,',')
  5         ,      0, t.more_text
  6         ,      '"' || t.more_text || '"') more_text
  7  FROM   t
  8  /
 
TEXT              MORE_TEXT
----------------- -----------------
ok                also ok
"1,2,3"           still no commas
comma-free        "so, now what?"
"8,9,10"          ",11,12,13"
