In a previous post, I described how I designed a SQLite relational database from an Excel table. It was a small example, so I hardcoded the data into the Python script. For my actual problem, I need to convert my Excel data into a SQLite database automatically. To do this, I used the win32com
module and the sqlite3
module included in Python 2.5.
Here is the table from my previous post. It shows some variables in in my C program. It shows the variable name, type, the module it belongs to, and a short description.

id | name | module | type | desc |
1 | foo | ModuleExt | double | Description of foo |
2 | bar | ModuleExt | double | Description of bar |
3 | knark | Module1 | int | Description of knark |
4 | wert | Module1 | double | Description of wert |
5 | jib | Module1 | double | Description of jib |
6 | laz | Module2 | double | Description of laz |
7 | kew | Module2 | double | Description of kew |
After installing the win32com
module from http://sourceforge.net/project/platformdownload.php?group_id=78018, I used the following code.
The Excel filename is example.xls and the table data begins at B14 (2nd column, 14th row) and ends at F20 (6th column, 20th row) in Sheet 1. The script uses a declarative approach to store the data in a Python list of lists. 21 dukes casino login. It creates a SQLite database named example.db and creates a connection to it. It then fills the database using the Python list data structure. Pop slots free vegas casino slot machine games. Finally, it displays the newly created database. The screen output is shown below.

If I want to interact with the newly created database using SQLite directly, I can run sqlite3 example.db Jixipix portrait painter 1 368. from my Cygwin bash command line. (Note the conn.commit()
line in my Python script is very important for this step to work. For some reason, I didn't see this in the Python documentation.) Here is an example session using SQLite directly with the new database.

You just saved me hours of time, and it worked straight off, and having not used Python before I'm very impressed by that too. Took me about 20 minutes to import 140 lines into SQLite which would have been loads of typing. thank you!
