# Similar LOAD DATA tests in another form

# All of this test portion has been run on a pre-WL5874 trunk

# differences are a bug.
# Regarding like_b its definition is the same as b's except
# that the constant default is replaced with a function
# default. Our expectation is that like_b would behave
# like b: if b is set to NULL, or set to 0000-00-00, or set to
# its default, then the same should apply to like_b. Same for
# like_c vs c.

# Regarding like_b its definition is the same as b's except

# its default, then the same should apply to like_b. Same for
