+**用 UpdateWrapper 新增数据** <Badge type="tip" text="^ v1.5.8" />
+
+在某些场景下，我们希望在新增数据时，新增数据字段内容是数据库的某个 `函数` 或者 `SQL片段` 生成的内容，而非我们手动设置的内容。
+例如，我们希望执行的 SQL 如下：
+
+```sql
+INSERT INTO `tb_account`(`user_name`,  `birthday`)
+VALUES (?, now())
+```
+
+> 以上 SQL 中，`birthday` 是由 `now()` 函数生成的内容。
+
+那么，java 代码如下：
+
+```java 9
+@Test
+public void testInsertWithRaw() {
+    Account account = new Account();
+    account.setUserName("michael");
+
+    Account newAccount = UpdateWrapper.of(account)
+//       .setRaw("birthday", "now()")
+//       .setRaw(ACCOUNT.BIRTHDAY, "now()")
+        .setRaw(Account::getBirthday, "now()")
+        .toEntity();
+
+    accountMapper.insert(newAccount);
+}
+```
+
+或者复杂一点的：
+
+```java 7
+@Test
+public void testInsertWithRaw() {
+    Account account = new Account();
+    account.setUserName("michael");
+
+    Account newAccount = UpdateWrapper.of(account)
+        .setRaw(Account::getBirthday, "(select xxx from ...)")
+        .toEntity();
+
+    accountMapper.insert(newAccount);
+}
+```
+其生成的 SQL 如下：
+
+```sql
+INSERT INTO `tb_account`(`user_name`,  `birthday`)
+VALUES (?, (select xxx from ...))
+```
+
+> 注意，通过 `UpdateWrapper.setRaw()` 的设置，会覆盖注解 `@Column.onUpdateValue` 配置的内容。
