> Key: CARBONDATA-1424
> URL: https://issues.apache.org/jira/browse/CARBONDATA-1424
> Project: CarbonData
> Issue Type: Bug
> Components: sql, test
> Affects Versions: 1.2.0
> Reporter: Sangeeta Gulia
> Assignee: Ravindra Pesala
> Priority: Minor
> Attachments: 3000_UniqData.csv
>

> Delete Operation is working incorrectly when subquery returns bad-record for
> a particular table.
> For the given query,
> delete from uniqdata_delete where cust_id in (select cust_id from
> uniqdata_delete limit 10);
> As an Example, if "select cust_id from uniqdata_delete limit 10" returns
> +----------+--+
> | cust_id |
> +----------+--+
> | NULL |
> | NULL |
> | NULL |
> | NULL |
> | 11000 |
> | 11001 |
> | 11002 |
> | 11003 |
> | 11004 |
> | 11005 |
> +----------+--+
> then the query should delete all rows where cust_id is Null or matches any
> values from the returned values(11000-11005) whereas it deletes only those
> records where customer id is from (11000-11005).
> I have attached the sample csv file which i have used for reference.
> To Regenerate the issue, you can use below commands :
> CREATE TABLE uniqdata_delete (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");
> LOAD DATA INPATH
> 'hdfs://localhost:54310/user/hduser/input-files/3000_UniqData.csv' into table
> uniqdata_delete
> OPTIONS('FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1');
> NOTE : Load should be such that starting rows of data should have null stored
> for cust_id field.
> delete from uniqdata_delete where cust_id in (select cust_id from
> uniqdata_delete limit 10);
