#       BEFORE ADDING NEW TEST CASES HERE !!!

#
# Please be aware, that this file will be sourced by several test case files
# stored within the subdirectory 't'. So every change here will affect 
# several test cases.


# The MySQL User Variables do not support the simulation of all 
# C-API field types.
#
# - There is no method to make an explicit assignment of a type to a variable.
# - The type of the variable can be only influenced by the writing style
#   of the value.
#
# The next tests should give an example for these properties.

#    MYSQL_TYPE of parameter  column type
#    MYSQL_TYPE_TINY          bigint(4)

# sufficient to simulate much of the behaviour of the C-API

# MySQL Manual (July 2004)                                                    #
# - Setting a numeric column to a value that lies outside the column's range. #
#   The value is clipped to the closest endpoint of the range.                #
# ...                                                                         #
# - For example, inserting the string '1999.0e-2' into an INT, FLOAT,         #
#   DECIMAL(10,6), or YEAR column results in the values 1999, 19.9921,        #
#   19.992100, and 1999.                                                      #
# That means there is an anomaly if a float value is assigned via string to   #
# a column of type bigint. The string will be cut from the right side to      #
# a "usable" integer value.                                                   #
