I have a table that needs to be sorted alphabetically by names that
aren't actually contained in the table *in sqlalchemy*. Only codes
representing the names are in the table. Like so...
Table 1:
|row code month value 1 A 201501 50 2 Z 201501 100 3 CO 201501 200 4 VA
201502 300 5 C 201502 300 |
Table 2:
|row code name 1 A Apple 2 C Cascade 3 CO Colorado 4 VA Virginia |
I need to sort *Table 1* the following:
* month
* name (found in Table 2)
What is the best technique to achieve these sorting results when the
sorting occurs on value not inherent in the table. I can't send the
joined product of Table 1 and Table 2. Although, I can join them
temporarily and remove the 'name' column if needed.
you need to produce rows that are a composite of table1 and table2, so
that a single row contains both the columns you want to receive as well
as the columns you intend to sort by. You do this using JOIN. SQL
would be:
SELECT table1.* FROM table1 JOIN table2 ON table1.code=table2.code ORDER
BY table2.name
