# title: Error converting string with hex representation of integer to smallint
|
|
# decription:
|
|
# Bug initially was detected when adapted some of GTCS-tests which tries to convert
|
|
# numeric values from all possible combinations of datatypes.
|
|
# Particularly, conversion error was when try to cast "0x7fffffffffffffff" to bigint.
|
|
# See letter to Alex et al, 08-JUN-2020 15:38.
|
|
#
|
|
# It was decided to check here not only cast to smallint but also to other integer dadatypes.
|
|
#
|
|
# Confirmed bug on 4.0.0.2188.
|
|
# Checked on 4.0.0.2191 - all OK.
