Thank you Akshay,

It is a very good code, It is putting all the files in one file, how can I spool each query to different CSV files. (Eg. Table1 to table 1.csv, table 2 to table2.csv ).

Best,
Hope

can it be spooled to different excel files?

Is it possible to spool it to different excel files? It is now dumping all the tables in one excel, which is not useful for my purpose.
Thanks in advance.

Difficult to believe. Unfortunately I can't test against an SQL DB, but this is what is piped into sqlplus -s dev01/password@dEV3 in Ashkay Hedge's fine proposal:
Code:
SET HEADING ON
SET WRAP OFF
SET TRIMSPOOL ON
SET TRIMOUT ON
SET PAGESIZE 50000
SET COLSEP ","
SET LINESIZE 500
SET NEWPAGE NONE
SET FEEDBACK OFF
SET VERIFY OFF
SET UNDERLINE OFF

SPOOL geo_JOB.csv
SELECT * FROM geo_JOB ;
SPOOL OFF

SPOOL geo_JOB1.csv
SELECT * FROM geo_JOB1 ;
SPOOL OFF
EXIT

There should be two .csv files created containing the data from the respective tables.

Hello Rudic,
Thank you for your time,
Are you still using the loop, I have so many tables to spool from and wanted to make sure my code is efficient.
In your code, where are you keeping the connection string? Can you please update the existing code with your changes?

Regards,
Hope

I didn't make it too clear: What i posted is what Akshay Hedge's would produce BEFORE it is piped into the sqlplus command. Try it literally, and post your results. Then run his code and post.

Thank you Akshay and Rudic
Sorry, I was putting comma between the tables in the table array. tables = ( table1, table2) it is all good now.

I really appreciate your expertise.
Regards,
Hope
