SQL Builder

A dynamic SQL builder for Java language.

Examples

Some usage examples: Select

QueryBuilder query = new QueryBuilder().select()
                                       .column("s.name")
                                       .column("count(s.impediments) AS total_impediments")
                                       .from()
                                       .table("sprint s")
                                       .groupBy()
                                       .column("s.name")
                                       .having()
                                       .column("total_impediments > 5")

The output is:

SELECT
    s.name,
    count(s.impediments) AS total_impediemnts
FROM
    sprint s
GROUP BY
    s.name
HAVING
    total_impediemnts > 5

Delete

DeleteQuery query = new DeleteQuery("account a").addWhere("a.id > 666")
                                                .addWhere("a.creation_date > '2013-01-01'");

The output is:

DELETE
FROM
    account a
WHERE
    a.id > 666
    AND a.creation_date > '2013-01-01'

Update

UpdateQuery query = new UpdateQuery("employee e").set("e.salary", "50000")
                                                 .addWhere("e.age > 40")
                                                 .addWhere("e.genre = 'female'");

The output is:

UPDATE
    employee e
SET
    e.salary = '50000'
WHERE
    e.age > 40
    AND e.genre = 'female'

Insert

InsertQuery query = new InsertQuery("persons").columns("id", "name", "age")
                                              .values(1, "foo", 30)
                                              .values(2, "bar", 23)
                                              .values(3, "hello", 54)
                                              .values(4, "world", 19);

The output is:

INSERT INTO
    persons (id, name, age)
VALUES
    (1, 'foo', 30),
    (2, 'bar', 23),
    (3, 'hello', 54),
    (4, 'world', 19)
