Michael Brown created IMPALA-5348:
-------------------------------------
Summary: remove mention of stringized timestamp literals with
interval expressions
Key: IMPALA-5348
URL: https://issues.apache.org/jira/browse/IMPALA-5348
Project: IMPALA
Issue Type: Bug
Components: Docs
Affects Versions: Impala 2.9.0
Reporter: Michael Brown
Assignee: John Russell
http://impala.apache.org/docs/build/html/topics/impala_literals.html mentions
being able to apply {{INTERVAL}} expressions to strings that will be able to be
coerced as timestamps,
bq. You can also use INTERVAL expressions to add or subtract from timestamp
literal values, such as '1966-07-30' + INTERVAL 5 YEARS + INTERVAL 3 DAYS.
but a user pointed out on dev@ that this is wrong:
{noformat}
[localhost:21000] > SELECT '1966-07-30' + INTERVAL 1 YEAR;
ERROR: AnalysisException: Operand ''1966-07-30'' of timestamp arithmetic
expression ''1966-07-30' + INTERVAL 1 YEAR' returns type 'STRING'. Expected
type 'TIMESTAMP'.
[localhost:21000] >
{noformat}
Documentation should be altered to fix this.
It looks like [~jrussell] pointed this out in IMPALA-2293, which was marked as
a dupe of IMPALA-1503.
