Oracle - How to save table as csv file from terminal with command - linux

Question

I have this process to save a table to CSV file but is not perfect:
sqlplus / as sysdba
set heading off
SET TERMOUT OFF
spool MY_TABLE.csv
select column_id||','||column_name||','||data_type||','||nullable||','||data_length from user1.MY_TABLE;
spool off;
exit
Issue with that is that can not turn off printing to terminal (I have SET TERMOUT OFF but that does not suppress the output for some reason).
I would like to run a sqlplus with a query from a terminal (instead of opening sqlplus and running from there)..
How to do that?

Answer 1

Example 1 for linux create_csv.sh displays the table data on the monitor screen.
#!/bin/sh
sqlplus -s / as sysdba <<EOF
set heading off
set termout OFF
SET FEEDBACK OFF
SET TAB OFF
set pause off
set verify off
SET UNDERLINE OFF
set trimspool on
set timing off
set echo off
set linesize 1000
set pagesize 0
SET COLSEP ','
spool test2.csv
select code,name,code_rail from alexs.all_station;
spool off
exit;
EOF
Example 2 for linux createv2_csv.sh does not display anything.
#!/bin/sh
$ORACLE_HOME/bin/sqlplus -s / as sysdba #csv2.sql
csv2.sql removed spaces and tabs between fields in the output file test2.csv
set heading off
set termout OFF
SET FEEDBACK OFF
SET TAB OFF
set pause off
set verify off
SET UNDERLINE OFF
set trimspool on
set echo off
set linesize 1000
set pagesize 0
set wrap off
spool test2.csv
select code||','||name||','||code_rail from alexs.all_station;
spool off
exit;
Example for Windows test_csv.bat
sqlplus -s user/password#net_alias < csv.sql
csv.sql
set heading off
set termout OFF
SET FEEDBACK OFF
SET TAB OFF
set pause off
set verify off
SET UNDERLINE OFF
set trimspool on
set timing off
set echo off
set linesize 1000
set pagesize 0
SET COLSEP ','
spool test.csv
select code,name,code_rail from alexs.all_station;
spool off
exit;
Example for Windows powershell script create_csv.ps1
# login DBA user
$username_dba = "system"
# PASSWORD DBA user !!!!
$password_dba = "manager"
# Connect without alias
$tnsalias_db = "(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = test.com)(PORT = 1521)))(CONNECT_DATA = (SID = test)))"
$sqlQuery =
#"
set heading off
set termout OFF
SET FEEDBACK OFF
SET TAB OFF
set pause off
set verify off
SET UNDERLINE OFF
set trimspool on
set timing off
set echo off
set linesize 1000
set pagesize 0
SET COLSEP ','
spool test.csv
select code,name,code_rail from alexs.all_station;
spool off
exit
"#
$sqlOutput = $sqlQuery | sqlplus -silent $username_dba/$password_dba#$tnsalias_db
