pandas-sqlalchemy-pivot

================

Provides pivot functionality for databases. Pivot aggregates are created

directly in the database. Reshaping into pivot is done in the pandas framework.

Usage

=====

    table.insert().execute(customer_id=1, yearmonth='201001', gender='male', price=10)

    table.insert().execute(customer_id=2, yearmonth='201001', gender='male', price=5)

    table.insert().execute(customer_id=3, yearmonth='201001', gender='female', price=10)

    select = sqlalchemy.select(table.c.yearmonth, table.c.gender, table.c.price)

    table = pivots.pivot_table_from_select(

                select,

                rows='yearmonth', cols='gender', values='price'

            )

    print table

Outputs:

                price

    gender     female  male

    yearmonth

    201001         10    15
