------------------------------------------
Summary: Delete Operation working incorrectly when subquery returns bad-record
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
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);
