ISSUE: 6117
|
|
TITLE: Varchar computed column length stores incorrect and invalid values for field
|
|
DESCRIPTION:
|
|
ONE of test parts works fine.
|
|
There is still problem with accommodation of resulting string in COMPUITED BY
|
|
column when its declared length ("varchar(20)") is equal to the total of lengths
|
|
of concatenated columns.
|
|
Because of this one of check statements was temp-ly disabled.
|
|
