["Daniel Sun (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-9159?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Sun updated GROOVY-9159:
-------------------------------
    Description: 
Reusing most of standard SQL syntax can make the learning curve smooth and avoid infringing the patent of Microsoft.

Here are some examples to show the proposed syntax:

*Filtering*
{code:java}
def numbers = [1, 2, 3]

def result =
	FROM numbers t       // t is an alias
	WHERE t.value <= 2
	SELECT t.value

assert [1, 2] == result
{code}

{code:java}
class Person {
	String name
	int age
}

def persons = [new Person(name: 'Daniel', age: 35), new Person(name: 'Peter', age: 10), new Person(name: 'Alice', age: 22)]

def result =
	FROM persons p       // p is an alias
	WHERE p.age > 15
	SELECT p.name

assert ['Daniel', 'Alice'] == result
{code}

TBD
