> Key: CARBONDATA-1808
> URL: https://issues.apache.org/jira/browse/CARBONDATA-1808
> Project: CarbonData
> Issue Type: Bug
> Components: sql
> Affects Versions: 1.3.0
> Environment: 3 node ant cluster
> Reporter: Chetan Bhat
> Assignee: anubhav tarar
> Priority: Minor
> Labels: Functional
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> Steps:
> User creates a table with char datatype --> Create table is success.
> 0: jdbc:hive2://10.18.98.34:23040> CREATE TABLE
> sensor_reading_blockblank_false(id char) STORED BY 'carbondata';
> +---------+--+
> | Result |
> +---------+--+
> +---------+--+
> No rows selected (0.688 seconds)
> User tries to alter the table using column name for char datatype in the same
> way.
> alter table sensor_reading_blockblank_false add columns(id1 char);
> Issue : Alter table fails with parsing error as shown below
> 0: jdbc:hive2://10.18.98.34:23040> alter table
> sensor_reading_blockblank_false add columns(id1 char);
> Error: java.lang.RuntimeException:
> BaseSqlParser>>>>
> Operation not allowed: alter table add columns(line 1, pos 0)
> == SQL ==
> alter table sensor_reading_blockblank_false add columns(id1 char)
> ^^^
> CarbonSqlParser>>>> [1.65] failure: ``('' expected but `)' found
> alter table sensor_reading_blockblank_false add columns(id1 char)
> ^
> (state=,code=0)
> Similar consistency issue is observed for varchar data type create table and
> alter table usage.

> Expected : The create table and alter table output should be consistent for
> char and varchar types for similar syntax usage.
