---------------------------------
Summary: TestSQLExpression.testCastFromTable causes unit test
failure
Key: TAJO-417
URL: https://issues.apache.org/jira/browse/TAJO-417
Project: Tajo
Issue Type: Bug
Components: operator/expression
Reporter: Hyunsik Choi
Assignee: Hyunsik Choi
Priority: Trivial
Fix For: 0.8-incubating
{code}
testSimpleEval("select '1980-04-01 01:50:01'::timestamp::bigint;", new String
[] {"323369401000"});
testSimpleEval("select ('1980-04-01 01:50:01'::timestamp)::bigint;", new
String [] {"323369401000"});
{code}
The above unit tests can cause failure due to the precision difference between
bigint value and the value casted from timestamp string. This patch eliminates
the difference by using only timestamp strings.
{code}
testSimpleEval("select '1980-04-01 01:50:01'::timestamp::bigint::timestamp",
new String [] {"1980-04-01 01:50:01"});
testSimpleEval("select cast (('1980-04-01 01:50:01'::timestamp)::bigint as
timestamp)",
new String [] {"1980-04-01 01:50:01"});
{code}
