> 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 |
> +---------------------------+--+

> 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
