Can you take a look at this
https://issues.apache.org/jira/browse/HIVE-24596? , most of the functions to
generate the constraints already exist in the class, also the constraints can
be printed using explain ddl select * from <tblname>. You can also take a look
at
this:https://github.com/apache/hive/blob/master/ql/src/test/queries/clientpositive/constraints_explain_ddl.q

> Currently show create table doesn’t pull any constraint info like not null,
> defaults, primary key.
> Example:
> Create table
>
> {code:java}
> CREATE TABLE TEST(
> col1 varchar(100) NOT NULL COMMENT "comment for column 1",
> col2 timestamp DEFAULT CURRENT_TIMESTAMP() COMMENT "comment for column 2",
> col3 decimal,
> col4 varchar(512) NOT NULL,
> col5 varchar(100),
> primary key(col1, col2) disable novalidate)
> ROW FORMAT SERDE
> 'org.apache.hadoop.hive.ql.io.orc.OrcSerde'
> STORED AS INPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat'
> OUTPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat';
> {code}
> Currently {{SHOW CREATE TABLE TEST}} doesn't show the column constraints.
> {code:java}
> CREATE TABLE `test`(
> `col1` varchar(100) COMMENT 'comment for column 1',
> `col2` timestamp COMMENT 'comment for column 2',
> `col3` decimal(10,0),
> `col4` varchar(512),
> `col5` varchar(100))
> ROW FORMAT SERDE
