Hello, Problem Statement: I have a requirement where I need to compare data from oracle and snowflake tables. I am using Apache Drill 1.17.0 for this. My tables have DATE column and the value from snowflake table is showing previous day's date. For example, if my actual value is '2021-05-20', Apache Drill returns '2021-05-19' from snowflake.
Fixes tried: * CONVERT_TO(date_column,'UTF8') - Gives previous date * CAST(date_column AS VARCHAR(10)) - Gives previous date * TO_CHAR(date_column) - Gives previous date * Converting to different timezone or UTC format doesn't work in Apache Drill. Workaround given in Apache Drill documentation for this timezone limitation did not make difference. Reference - http://drill.apache.org/docs/data-type-conversion/#time-zone-limitation * Altered timezone of snowflake and then inserted data into table, still Apache Drill gives previous date * CAST(date_column AS TIMESTAMP) - Gives correct date when queried separately on snowflake table, but gives previous date when I join this table to my corresponding oracle table for validation Please help me out with solution for this issue and revert if any more details required. Thanks in advance!
