Description

Inaccurate result displays on presto CLI while select Query after change data type Query

Steps to reproduce:
On Beeline:
1) Create Table:
CREATE TABLE uniqdata (CUST_ID int,CUST_NAME String,ACTIVE_EMUI_VERSION string, DOB timestamp, DOJ timestamp, BIGINT_COLUMN1 bigint,BIGINT_COLUMN2 bigint,DECIMAL_COLUMN1 decimal(30,10), DECIMAL_COLUMN2 decimal(36,10),Double_COLUMN1 double, Double_COLUMN2 double,INTEGER_COLUMN1 int) STORED BY 'org.apache.carbondata.format' TBLPROPERTIES ("TABLE_BLOCKSIZE"= "256 MB");

2) Load Data
LOAD DATA INPATH 'hdfs://localhost:54310/Data/uniqdata/2000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',' , 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1');

3) Execute Query:
a)desc uniqdata:
outpurt:
---------------------------------------------+

col_name

data_type

comment

---------------------------------------------+

CUST_ID	int	NULL
CUST_NAME	string	NULL
ACTIVE_EMUI_VERSION	string	NULL
DOB	timestamp	NULL
DOJ	timestamp	NULL
BIGINT_COLUMN1	bigint	NULL
BIGINT_COLUMN2	bigint	NULL
DECIMAL_COLUMN1	decimal(30,10)	NULL
DECIMAL_COLUMN2	decimal(36,10)	NULL
Double_COLUMN1	double	NULL
Double_COLUMN2	double	NULL
INTEGER_COLUMN1	int	NULL

---------------------------------------------+

b)alter table uniqdata change decimal_column1 decimal_column1 decimal(36,12);

c)select decimal_column1 from uniqdata;

output:
---------------------------+

decimal_column1

12345678913.123400000000
12345678914.123400000000

On Presto CLI:
1)Execute Queries:
a) desc uniqdata;

b) select decimal_column1 from uniqdata;

Expected Output: Same as in beeline(no change in value before the decimal.

Actual Output:

decimal_column1
