ISSUE: 6636
|
|
TITLE: Error converting string with hex representation of integer to smallint
|
|
DESCRIPTION:
|
|
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.
