- # Tests for prepared statements: conversion of parameters #
- # #
- # Please don't #
- # - try to execute this script in ANSI mode, because many statements #
- # will fail due to the strict type checking #
- # - reuse such ugly assignments like timestamp column = float value . #
- # I included them only for controlling purposes. #
- ########################################################################
- #
- # NOTE: PLEASE SEE ps_1general.test (bottom)
- # 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.

- #################### Some overflow experiments ################################
- # #
- # 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. #
