[jira] [Created] (CARBONDATA-1695) Inaccurate result displays on
presto CLI while select Query after change data type Query
Vandana Yadav created CARBONDATA-1695:
-----------------------------------------
Summary: Inaccurate result displays on presto CLI while select Query after change data type Query
Key: CARBONDATA-1695
URL: https://issues.apache.org/jira/browse/CARBONDATA-1695
Project: CarbonData
Issue Type: Bug
Components: presto-integration
Affects Versions: 1.3.0
Environment: spark 2.1
Reporter: Vandana Yadav
Priority: Minor
Attachments: 2000_UniqData.csv
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
