[Pytables-users] Some method like a "table.readWhereSorted"

Hi, Is there a way that I could have the ability of readWhere (i.e., specify condition, and fast result) but also using a CSIndex so that the rows come sorted in a particular order? I checked readSorted() but it is iterative and does not allow to specify a condition. Julio --

Hi Anthony Thanks again.* *If it is a problem related to floating-point precision, I might use an Int64Col instead, since I don't need the timestamp miliseconds. Julio On Wed, Apr 10, 2013 at 1:17 PM, Anthony Scopatz wrote: > On Wed, Apr 10, 2013 at 7:44 AM, Julio Trevisan

[Pytables-users] ReadWhere() with a Time64Col in the condition

Hi, I am using a Time64Col called "timestamp" in a condition, and I noticed that the condition does not work (i.e., no rows are selected) if I write something as: for row in node.where("timestamp == %f" % t): ... However, I had this idea of dividing the values by, say 1000, and it does work:

[Pytables-users] Reading single column from table

Hi, I just joined this list, I am using PyTables for my project and it works great and fast. I am just trying to optimize some parts of the program and I noticed that zipping the tuples to get one tuple per column takes much longer than reading the data itself. The thing is that readWhere() retur
