JavaQ

JavaQ takes care of building the sql query for you, rescuing you from the pain of remembering syntax for different dialects. With Java's static typing, JavaQ reduces the chances of making structural mistakes in the query.

Using JavaQ

import static com.javaq.JavaQ.select;

Select All

    select().from("EMPLOYEE").sql() 

Where Clause

    select("ID", "NAME").from("EMPLOYEE").where("ID = 1").sql()

Operators (AND/OR/LIKE/IN)

• AND/OR

  select("ID", "NAME").from("EMPLOYEE")
      .where("ID = 1").and("NAME = 'BATMAN'")
      .sql()
  

  select("ID", "NAME").from("EMPLOYEE")
      .where("ID = 1").or("NAME = 'BATMAN'")
      .sql()
  

• IN

  select("ID", "NAME").from("EMPLOYEE")
      .where("ID")
        .in(select("ID").from("AWARD_WINNERS"))
      .or("NAME = 'BATMAN'")
      .sql()
  

  select("ID", "NAME").from("EMPLOYEE")
      .where("ID").in("1", "2")
      .sql()
  

• LIKE

  select("ID", "NAME").from("EMPLOYEE")
      .where("NAME").like("%BATMAN%")
      .sql()
  

Joins

• INNER JOIN

  select("ID", "NAME").from("EMPLOYEE")
      .join("ADDRESS").on("ADDRESS.ID = EMPLOYEE.ADDRESS_ID")
      .where("ID = 1").or("NAME = 'BATMAN'")
      .sql()
  

• LEFT JOIN

  select("ID", "NAME").from("EMPLOYEE")
      .leftJoin("ADDRESS").on("ADDRESS.ID = EMPLOYEE.ADDRESS_ID")
      .where("ID = 1").or("NAME = 'BATMAN'")
      .sql()
  

Order By

    select("ID", "NAME").from("EMPLOYEE")
        .orderBy("ID", Order.OrderType.ASC)
        .sql()

Group By

    select("NAME", "COUNT(*)").from("EMPLOYEE")
        .groupBy("NAME")
        .orderBy("COUNT(*)", ASC)
        .sql()

Limit

    select("NAME", "COUNT(*)").from("EMPLOYEE")
          .groupBy("NAME")
          .orderBy("COUNT(*)", ASC)
          .limit(10)
          .sql()
