[Pytables-users] Question about pytables

[Vineet J. <vin...@ya...>]

Couple of questions about pytables:

 

I built two samples. One with pysqlite and one with pytables and I found
pytables to be about 20 times faster than the pysqlite version and used
a lot less space. Let me commend you on a great application. 

 

I have the following requests/questions:

 

1.	Update certain rows in a table and append to a table. The latter
you handle but am not sure how to do the former. Will updating rows ever
be supported?

 

2.	For arrays or rows returned from a table. How can you do the
following:

Row1 = table1.read()

Row2 = table2.read()

FinalRow = row1+row2

Without having to loop through them. 

 

      3 Something useful found in pysqlite, and the postgress db driver
is the ability to access field names directly:

 

row = table.read()

high = row[10000].high  (where high is a field of the table)

 

4 Is there any way the rows returned from table can be treated as
numarray objects?

 

Thanks for your replies,
