How to connect to Oracle DB using batch file - windows

Question

I am automating a process where I have to connect to Oracle database and run a script automatically.
Can somebody help me in achieving this.
I have written a script but when I am executing the below scripts it's not returning any output.
Code :
#echo off
set user_name=<username>
set password=<password>
set net_service_name= <tns_name>
echo exit | sqlplus -s %user_name%/%password%#%net_service_name% #f:\test.sql
pause
I am using Oracle 11g. I am connecting to database of a specific region.
Also, I need to connect to database as an admin user.

I think the problem is in the space in net_service_name. "-S" is silent mode for sqlplus. For diagnostics, remove this key and add rem #echo off.
For example 1. The space in net_service_name.
rem #echo off
set user_name=scott
set password=tiger
set net_service_name= esmd
echo exit | sqlplus -s %user_name%/%password%#%net_service_name% #C:\upwork\stackoverflow\bat_sql\sqltest.sql
pause
output:
C:\upwork\stackoverflow\bat_sql>echo exit | sqlplus -s scott/tiger# esmd #C:\upwork\stackoverflow\bat_sql\sqltest.sql
Usage: SQLPLUS [ [<option>] [<logon>] [<start>] ]
where <option> ::= -H | -V | [ [-L] [-M <o>] [-R <n>] [-S] ]
<logon> ::= <username>[/<password>][#<connect_string>] | / | /NOLOG
<start> ::= #<URI>|<filename>[.<ext>] [<parameter> ...]
"-H" displays the SQL*Plus version banner and usage syntax
"-V" displays the SQL*Plus version banner
"-L" attempts log on just once
"-M <o>" uses HTML markup options <o>
"-R <n>" uses restricted mode <n>
"-S" uses silent mode

For example 2.
rem #echo off
set user_name=scott
set password=tiger
set net_service_name=esmd
echo exit | sqlplus -s %user_name%/%password%#%net_service_name% #C:\upwork\stackoverflow\bat_sql\sqltest.sql
pause
output:
C:\upwork\stackoverflow\bat_sql>echo exit | sqlplus -s scott/tiger#esmd #C:\upwork\stackoverflow\bat_sql\sqltest.sql
SYSDATE
--------

C:\upwork\stackoverflow\bat_sql>pause
For example 3. Connect as sysdba.
rem #echo off
set user_name=sys
set password=manager
set net_service_name=esmd as sysdba
echo exit | C:\oracle\instantclient_11_2\sqlplus.exe -s %user_name%/%password%#%net_service_name% #C:\upwork\stackoverflow\bat_sql\sqltest.sql
pause
output:
C:\upwork\stackoverflow\bat_sql>echo exit | C:\oracle\instantclient_11_2\sqlplus.exe -s sys/manageresmd#esmd as sysdba #C:\upwork\stackoverflow\bat_sql\sqltest.sql
SYSDATE

C:\upwork\stackoverflow\bat_sql>pause
For example 4. Connect as sysdba.
rem #echo off
set user_name=sys
set password=manager
set net_service_name=esmd as sysdba
rem
(
echo conn %user_name%/%password%#%net_service_name%
echo #C:\upwork\stackoverflow\bat_sql\sqltest.sql
echo exit
)| sqlplus -s /nolog
pause
output:
C:\upwork\stackoverflow\bat_sql>(
echo conn sys/manageresmd#esmd as sysdba
echo #C:\upwork\stackoverflow\bat_sql\sqltest.sql
echo exit
) | sqlplus -s /nolog
Connected.
SYSDATE

For example sqltest.sql.
C:\upwork\stackoverflow\bat_sql>more sqltest.sql
select sysdate from dual;
