Hi Team,

I want to extract data like below using shell scripting and spool into .csv file

Select e.*
d.data_id||','||
d.insert_date
from
employee e,
data d
where
...
...
...

Here when i fetch all columns from employee table giving concatenation symbol ||','|| gives me an error.
Giving just a comma , doesn't spool the data in proper alignment.

what should i give?

please advise

Regards
Dhivya

Can you show us what you get?

Before, Please read OraFAQ Forum Guide and How to use [code] tags and make your code easier to read.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code, use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version, with 4 decimals.

Regards
Michel

COLSEP in SQL*Plus, maybe?

SQL> set colsep ,
SQL> select * from dept;

    DEPTNO,DNAME         ,LOC
----------,--------------,-------------
        10,ACCOUNTING    ,NEW YORK
        20,RESEARCH      ,DALLAS
        30,SALES         ,CHICAGO
        40,OPERATIONS    ,BOSTON

SQL>

(By the way, you are missing a comma behind "e.*")

I use the following format to export and insert small tables between Oracle systems.

Since sqlplus converts 2 single quotes to 1 single quote, I use many single quotes.

The replace converts O'Hara to O''Hara (see the fifth line) because the two single quotes will
be replaced by one quote by sqlplus when the insert statement is run.
