Vineet Garg updated HIVE-18853:
-------------------------------
Description:
{code:sql}
create table ttest(i int constraint nn1 not null enable);
alter table ttest change i i int constraint nn2 not null enable);
{code}
The above statements will end up creating multiple not null constraints on
column i/j.
{code:sql}
desc formatted ttest;
# Not Null Constraints
Table: constraints.ttest
Constraint Name: nn1
Column Name: i
Constraint Name: nn2
Column Name: i
{code}
was:
{code:sql}
create table ttest(i int constraint nn1 not null enable);
alter table ttest change i j int constraint nn2 not null enable);
{code}
The above statements will end up creating multiple not null constraints on
column i/j.
{code:sql}
desc formatted ttest;
# Not Null Constraints
Table: constraints.ttest
Constraint Name: nn1
Column Name: null
Constraint Name: nn2
Column Name: j
{code}
> Alter table change column shouldn't let define same constraint on a column
> with existing constraint
