ethanwhite: Tests are all passing (locally at least). It would be worth testing out a few other datasets using both flat file and database formats to confirm that this didn't break any edge cases.
henrykironde: I think mysql parameter should be ?
henrykironde: Not sure but will do some tests later
ethanwhite: > I think mysql parameter should be ?

Yeah, I thought so originally too, but couldn't get to it work and then looked at the docs again.

> Not sure but will do some tests later

Looks like the tests are failing on CI so no need to worry about this one until I get that sorted out.
ethanwhite: Looks like I broke something on Python 2 (hooray for CI!). I'll take a look when I get the chance and update later.
ethanwhite: Looks like it's just MySQL on Python 2, so some sort of lovely edge case. It fails when trying to insert the first line of `mammal-masses` (to provide an example). First line is the insert statement, second line is the first of the sets of values to be inserted by `executemany`, and then the error message:

```
Creating table mammal_masses.MammalMasses...
INSERT INTO mammal_masses.MammalMasses (continent, status, sporder, family, genus, species, log_mass_g, comb_mass_g, reference) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s)
[u'AF', u'extant', u'Artiodactyla', u'Bovidae', u'Addax', u'nasomaculatus', '4.85', '70000.3', u'60']
INSERT INTO mammal_masses.MammalMasses (continent, status, sporder, family, genus, species, log_mass_g, comb_mass_g, reference) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s)
(1064, u"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '4.85'', b''70000.3'', '60'),('AF', 'extant', 'Artiodactyla', 'Bovidae', 'Aepycer' at line 1")
```

The error message has `b''70000.3''` instead of `b"70000.3"`. Not sure if this is the source of the issue or just a display quick.

SQL INSERT statements use custom quoting rather than parameter binding 
Any reason you can't use parameter binding for binding values to SQL statements such as  `INSERT (...) VALUES (...)`? For most SQL engines, it's both faster and safer than using custom quoting and direct interpolation of values. It's certainly a lot less code (because the SQL engine does most of the type conversion and quoting).
