Re: [Tutor] best way to tell if i am connected to the internet

[Jalil]

ping a host on the net if you get an echo response back you are good.
better yet ping the host  page you are scraping.

Re: [Tutor] python cx_Oracle.LOB

[Jalil]

Thanks Jason,
here is my code



import cx_Oracle

db = cx_Oracle.connect('xx','x','')
cursor=db.cursor()
#cursor.execute('set long 5000')
#sqlen="""set long 5000"""
#cursor.execute(sqlen)
sqtext="""select TExt from sq_updates where action_id= '851151'"""
cursor.execute(sqtext)
rettext = cursor.fetchmany()

print rettext

An example of your code would help. According to the cx_oracle docs at
http://www.python.net/crew/atuining/cx_Oracle/html/index.html under the
LOB Objects heading:

6. LOB Objects

*NOTE*: This object is an extension the DB API. It is returned whenever
Oracle CLOB, BLOB and BFILE columns are fetched.

*NOTE*: Internally, Oracle uses LOB locators which are allocated based on
the cursor array size. Thus, it is important that the data in the LOB object
be manipulated before another internal fetch takes place. The safest way to
do this is to use the cursor as an iterator. In particular, do not use the
fetchall() method. The exception "LOB variable no longer valid after
subsequent fetch" will be raised if an attempt to access a LOB variable
after a subsequent fetch is detected.

 *fileexists*( ) Return a boolean indicating if the file referenced by the
BFILE type LOB exists.

 *getfilename*( ) Return a two-tuple consisting of the directory alias and
file name for a BFILE type LOB.

 *read*( [offset = 1, [amount]]) Return a portion (or all) of the data in
the LOB object.

 *setfilename*( dirAlias, name) Set the directory alias and name of the
BFILE type LOB.

 *size*( ) Returns the size of the data in the LOB object.

 *trim*( [newSize = 0]) Trim the LOB to the new size.

 *write*( data, [offset = 1]) Write the data to the LOB object at the
given offset. Note that if you want to make the LOB value smaller, you must
use the trim() function.
I'd try the read method on your object.

The file gdal.py and gdal.pyc are in : /usr/lib/python2.4/site-packages,
but still it gives this error.
