# capi3-5.0: Prepare a statement, and check we can retrieve the number of

# capi3-5.1: Check we can retrieve column names (before statement execution)
# capi3-5.2: Check we can retrieve column names in UTF-16
# capi3-5.3: Step the statement.
# capi3-5.4: Check the types of the values.
# capi3-5.5: Check the values can be retrieved as integers.
# capi3-5.6: Check the values can be retrieved as UTF-8 text.
# capi3-5.7: Check the values can be retrieved as UTF-16 text.
# capi3-5.8: Check that the types of the values have not been altered by
#            retrieving the values as text.

# Test cases capi3-5.9 - capi3-5.14 are a repeat of 3-8, with a different
