Comparing bigints and varchars or chars may result to wrong result, for example: CREATE TABLE test_a (appid1 varchar(256), appid2 char(20)); INSERT INTO test_a VALUES ('2882303761517473127', '2882303761517473127'), ('2882303761517473276','2882303761517473276'); SET hive.strict.checks.type.safety=false; SELECT appid1 FROM test_a WHERE appid1 = 2882303761517473127; SELECT appid2 FROM test_a WHERE appid2 = 2882303761517473127; Both queries will output the row: ('2882303761517473276','2882303761517473276') -- This message was sent by Atlassian Jira (v8.3.4#803005)
