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.
{color:#d04437}*Note: The syntax can be changed before introducation*{color}
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 AND p.age <= 35
SELECT p.name
assert ['Daniel', 'Alice'] == result
{code}
