> 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)
