*	[SPARK-17258][SQL] Parse scientific decimal literals as decimals	Herman van Hovell	2016-10-04	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	## What changes were proposed in this pull request? Currently Spark SQL parses regular decimal literals (e.g. `10.00`) as decimals and scientific decimal literals (e.g. `10.0e10`) as doubles. The difference between the two confuses most users. This PR unifies the parsing behavior and also parses scientific decimal literals as decimals. This implications in tests are limited to a single Hive compatibility test. ## How was this patch tested? Updated tests in `ExpressionParserSuite` and `SQLQueryTestSuite`. Author: Herman van Hovell <hvanhovell@databricks.com> Closes #14828 from hvanhovell/SPARK-17258.
*	[SPARK-17117][SQL] 1 / NULL should not fail analysis	petermaxlee	2016-08-18	1	-18/+66
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	## What changes were proposed in this pull request? This patch fixes the problem described in SPARK-17117, i.e. "SELECT 1 / NULL" throws an analysis exception: ``` org.apache.spark.sql.AnalysisException: cannot resolve '(1 / NULL)' due to data type mismatch: differing types in '(1 / NULL)' (int and null). ``` The problem is that division type coercion did not take null type into account. ## How was this patch tested? A unit test for the type coercion, and a few end-to-end test cases using SQLQueryTestSuite. Author: petermaxlee <petermaxlee@gmail.com> Closes #14695 from petermaxlee/SPARK-17117.
*	[SPARK-17013][SQL] Parse negative numeric literals	petermaxlee	2016-08-11	1	-13/+13
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	## What changes were proposed in this pull request? This patch updates the SQL parser to parse negative numeric literals as numeric literals, instead of unary minus of positive literals. This allows the parser to parse the minimal value for each data type, e.g. "-32768S". ## How was this patch tested? Updated test cases. Author: petermaxlee <petermaxlee@gmail.com> Closes #14608 from petermaxlee/SPARK-17013.
*	[SPARK-17015][SQL] group-by/order-by ordinal and arithmetic tests	petermaxlee	2016-08-11	1	-0/+178
	## What changes were proposed in this pull request? This patch adds three test files: 1. arithmetic.sql.out 2. order-by-ordinal.sql 3. group-by-ordinal.sql This includes https://github.com/apache/spark/pull/14594. ## How was this patch tested? This is a test case change. Author: petermaxlee <petermaxlee@gmail.com> Closes #14595 from petermaxlee/SPARK-17015.
