+查询,实现`DefaultDSLQueryService`接口
+```java
+    // select * from user where name = ? limit 0,1
+   createQuery().where("name","张三").single();
+```
+```java
+    // select * from user where name = ? or name = ?
+   createQuery().where("name","张三").or().is("name","李四").list();

+   createQuery().where("name","张三").nest().gt("age",10).or().lt("age",20).end().list();
+```
+
+修改,实现`DefaultDSLUpdateService`接口
+```java
+    // update user set ... where name = ?
+   createUpdate(data).where("name","张三").exec();
+    //不会修改为null的属性,
+```
+
+```java
+    // update user set name=?,age=? where name = ?
+   createUpdate(data).include("name","age").where("name","张三").exec();
+```
+
+```java
+    // update user set name=? where name = ?
+   createUpdate().set("name","新张三").where("name","张三").exec();
+```
+
+删除,实现`DefaultDSLDeleteService`接口
+```java
+//delete from user where name = ?
+createDelete().where("name","张三").exec();
+```
+
+查改删,条件使用的方式都相同.
