Question

I’m trying to debug a SQL statement generated with sqlite3 python module…

c.execute("SELECT * FROM %s WHERE :column = :value" % Photo.DB_TABLE_NAME, {"column": column, "value": value})

It is returning no rows when I do a fetchall()

When I run this directly on the database

SELECT * FROM photos WHERE album_id = 10

I get the expected results.

Is there a way to see the constructed query to see what the issue is?

Answer 1

the problem here is that the string values are automatically embraced with single quotes. You can not dynamically insert column names that way.

Concerning your question, I’m not sure about sqlite3, but in MySQLdb you can get the final query as something like (I am currently not at a computer to check):

statement % conn.literal(query_params)
