- step statementprocedure
Steps statement and returns one of the following:
- 'row: a row was returned (SQLITE_ROW)
- 'done: the statement is done executing (SQLITE_DONE)
- #f: step failed due to error
#f is only ever returned if raising exceptions is disabled. Completion of execution is still considered a "success" and so the true value 'done is returned, rather than #f.
Upon database error, the statement is reset.
