  • Hi All,
    My name is Ankit Shrivastava and I am a Data Engineer.
    Today this #vlog is regarding #sql Interview question to identify range of status with given date #dataengineering #dataanalytics
    DDL for practice:-
    create table test_status (date_value date,state varchar(100));
    insert into test_status values ('01-01-2024','Success');
    insert into test_status values ('01-02-2024','Success');
    insert into test_status values ('01-03-2024','Success');
    insert into test_status values ('01-04-2024','Fail');
    insert into test_status values ('01-05-2024','Fail');
    insert into test_status values ('01-06-2024','Success');
