Fatal Python error: Py_Initialize: Unable to get the locale encoding

Hi ,

If you are getting the above ERROR message while configuring PL/PYTHON module, then please use the below steps to configure in PostgreSQL. We need to use PYTHON 3.2 Version due to some bugs in earlier version.

Step 1
=====
Download Link: http://www.activestate.com/activepython/downloads/thank-you?dl=http://downloads.activestate.com/ActivePython/releases/3.2.2.3/ActivePython-3.2.2.3-linux-x86.tar.gz"

Step 2
=====

-bash-4.1$ export PYTHONPATH=/opt/ActivePython-3.2/bin:$PATH
-bash-4.1$ export PYTHONHOME=/opt/ActivePython-3.2/
-bash-4.1$ export LD_LIBRARY_PATH=/opt/ActivePython-3.2/lib/

Step 3
=====

-bash-4.1$ ./pg_ctl -D ../data/ stop -mf
waiting for server to shut down.... done
server stopped

-bash-4.1$ ./pg_ctl -D ../data/ start
server starting

Step 4
=====

-bash-4.1$ ./psql -p 5434 postgres

Password:
psql.bin (9.1.4)
Type "help" for help.
postgres=# CREATE LANGUAGE plpython3u;
CREATE LANGUAGE
postgres=#

Step 5
=====

postgres=#     CREATE OR REPLACE FUNCTION pymax (a integer, b integer) RETURNS integer AS
    $$
        if a > b:
          return a
        return b
    $$ LANGUAGE plpython3u;
CREATE FUNCTION

postgres=# SELECT pymax(3,4);
 pymax
-------
     4
(1 row)

Parallel Operations With pl/pgSQL

Hi, I am pretty sure that, there will be a right heading for this post. For now, i am going with this. If you could suggest me proper heading, i will update it :-) OK. let me explain the situation. Then will let you know what i am trying to do here, and how i did it. Situation here is, We have a table, which we need to run update on “R” no.of records. The update query is using some joins to get the desired result, and do update the table.  To process these “R” no.of records, it is taking “H” no.of hours. That too, it’s giving load on the production server. So, we planned to run this UPDATE as batch process.  Per a batch process, we took “N” no.or records. To process this batch UPDATE, it is taking “S” no.of seconds. With the above batch process, production server is pretty stable, and doing great. So, we planned to run these Batch updates parallel.  I mean, “K” sessions, running different record UPDATEs. Of-course, we can also increase the Batch size here.  But

How To Send E-Mail From PostgreSQL

Hi , If you want to send E-Mails from PostgreSQL, then use the below Python 3.2 Script as below. I have used ActivePython 3.2 with PostgreSQL 9.1 for sending E-Mails from PostgreSQL. If you want to configure the Python 3.2 with PostgreSQL 9.1 then, please refer the below steps. http://manojadinesh.blogspot.in/2012/06/fatal-python-error-pyinitialize-unable.html Once, your Python 3.2 successful then follow the below steps to send an e-mail. Step 1 ===== postgres=# CREATE OR REPLACE FUNCTION public.send_email(_from Text,_password Text,smtp Text,port INT,receiver text, subject text, send_message text) RETURNS TEXT  LANGUAGE plpython3u AS $function$ import smtplib sender = _from receivers = receiver message = ("From: %s\nTo: %s\nSubject: %s\n\n %s"  % (_from,receiver,subject,send_message)) try:   smtpObj = smtplib.SMTP(smtp,port)   smtpObj.starttls()   smtpObj.login(_from, _password)   smtpObj.sendmail(sender, receivers,message)   print ('Successf

Pipelined Table Functions:- [ORACLE] =========================== If you want to return multiple rows to the calling environment, then piplined table functions is prefred. It will increase the dbperformance as well. Ex:- Step 1: ----------- CREATE TABLE EMP(EMPNO INT,ENAME VARCHAR2(10),SAL INT); Step 2: ----------- Insert sample data. Step 3: ----------- Create an object for the row type casting. CREATE OR REPLACE TYPE emp_row AS OBJECT ( empno INT, ename VARCHAR2(20), SAL INT ); Step 4: ----------- Create a Return Type for the pipelined function. CREATE OR REPLACE TYPE emp_table_type AS TABLE OF emp_row; Step 5: ----------- CREATE OR REPLACE FUNCTION emp_pipe_function RETURN emp_table_type PIPELINED IS BEGIN FOR rec in (select * from emp) LOOP PIPE ROW (emp_row(rec.empno,rec.ename,rec.sal)); END LOOP; RETURN; END; Step 6: ---------- SQL> select * from table(emp_pipe_function); EMPNO ENAME SAL ---------- ----
