Can I use SQLPlus to execute a .sql file?

Question

I have a .sql file with the following code:

delete from stalist
where stalistid=4944
/
insert into stalist
(stalistid, staid)
(select distinct 4944, staid
from staref
Where staid in(
3797,3798,
3870,4459,
3871,3872,
3876,3877,
0
))
/
commit
/

I would like to use Python to execute this file from SQLPlus. Is this possible? I do not have any python experience in this type of work and could use some help. Thank you!

Solution 1

see this tutorial: http://moizmuhammad.wordpress.com/2012/01/31/run-oracle-commands-from-python-via-sql-plus/

i.e.

from subprocess import Popen, PIPE

#function that takes the sqlCommand and connectString and retuns the output and #error string (if any)

def runSqlQuery(sqlCommand, connectString):

session = Popen(['sqlplus', '-S', connectString], stdin=PIPE, stdout=PIPE, stderr=PIPE)
session.stdin.write(sqlCommand)
return session.communicate()

should do it (where sqlCmmand is "@scriptname.sql").

Below is an example of how to do this. You need to read the file and pass the entire string as a command.

(username, password, host) = ("user","password","host") 

conn_string = " %s/%s@%s "% (username,password,host)
session = Popen(['sqlplus','-S', conn_string], stdin=PIPE, stdout=PIPE, stderr=PIPE)
logging.info("Starting sqlplus")

sql_file = '%s/%s' % (sql_folder, file)
logging.info("Running " + sql_file)
f= open(sql_file,'r')
cmd = f.read()
session.stdin.write(cmd)

stdout, stderr = session.communicate()
