Description

The attached query run on the attached data file produces the following results:

*************************** 1. row ***************************

                     id: NULL

                      a: 0.0000

                      b: NULL

                      c: NULL

                      d: 0.00000

                      e: NULL

this_should_be_a_bigint: 2.3456

      what_it_should_be: 1

                      f: NULL

*************************** 2. row ***************************

                     id: NULL

                      a: 0.0000

                      b: NULL

                      c: NULL

                      d: 0.00000

                      e: NULL

this_should_be_a_bigint: 2.3456

      what_it_should_be: 1

                      f: NULL

*************************** 3. row ***************************

                     id: NULL

                      a: 0.0000

                      b: NULL

                      c: NULL

                      d: 0.00000

                      e: NULL

this_should_be_a_bigint: 2.3456

      what_it_should_be: 1

                      f: NULL

3 rows in set (0.00 sec)

Notice that the result column this_should_be_a_bigint returns a floating point number. This is wrong. The 2.3456 value suspiciously appears in an earlier column calculation in the query.
