Summary: Incorrect result with alter query in while adding new column to the table
Key: CARBONDATA-1710
URL:
https://issues.apache.org/jira/browse/CARBONDATA-1710 Project: CarbonData
Issue Type: Bug
Components: data-query
Affects Versions: 1.3.0
Environment: spark 2.1
Reporter: Vandana Yadav
Priority: Minor
Attachments: 2000_UniqData.csv
Incorrect result with alter query while adding new column to the table
Steps to reproduce:
1) Create table:
CREATE TABLE uniqdata_alter (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 into the table:
LOAD DATA INPATH 'HDFS_URL/BabuStore/Data/uniqdata/2000_UniqData.csv' into table uniqdata_alter 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) add column query with wrong precision and scale:
alter table uniqdata_alter add columns (decimal_column3 decimal(10,14))
output:
Error: org.apache.spark.sql.AnalysisException: Decimal scale (14) cannot be greater than precision (10).; (state=,code=0)
b)add column query with correct precision and scale:
alter table uniqdata_alter add columns (decimal_column3 decimal(10,4));
Expected Output:
it should successfully add a new column to the table.
Actual output:
Error: org.apache.spark.sql.AnalysisException: Decimal scale (14) cannot be greater than precision (10).; (state=,code=0)
