NumPy arrays with SQLite

Question

The most common SQLite interface I\'ve seen in Python is sqlite3, but is there anything that works well with NumPy arrays or recarrays? By that I mean one that reco

Answer 1

I found at least three Python packages to interface SQLite and NumPy:

• esutil.sqlite_util, which is part of esutil
• hydroclimpy.io.sqlite
• my own RecSQL (available from github.com/orbeckst/RecSQL)

Each of these packages has to deal with the problem that SQLite (by default) only understands standard Python types and not the NumPy data types such as numpy.int64.

RecSQL 0.7.8+ works for me (most of the time) but I consider it a pretty bad hack and glancing over the code, esutil.sqlite_util appears to be more mature.
