How can I do database queries using functions like
db_query() in my
DrupalWebTestCase sub-class? When I try to run them, I get an error:
SQLSTATE: Syntax error or access violation: 1064 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 'simpletest421143 WHERE (nid = '1')' at line 2`
I think it's because the tables aren't properly prefixed, yet I see the prefix in the error string. So it seems that it's trying to prefix, but not doing it properly.
How can I use these functions in my testing class?
