-queryWrapper.from(ACCOUNT)

 其查询生成的 Sql 如下：
 
 ```sql
-SELECT * FROM `tb_account`
-    LEFT JOIN `tb_account` AS `a1`
-        ON `a1`.`id` = `tb_account`.`parent_id`
-    LEFT JOIN `tb_account` AS `a2`
-        ON `a2`.`id` = `tb_account`.`parent_id`
-WHERE `tb_account`.`id` >= ?
+SELECT
+    ` ar `.` content `,
+    ` a1 `.` id `,
+    ` a2 `.` age `
+FROM
+    ` tb_article ` AS ` ar `
+    LEFT JOIN ` tb_account ` AS ` a1 ` ON ` a1 `.` id ` = ` ar `.` account_id `
+    LEFT JOIN ` tb_account ` AS ` a2 ` ON ` a2 `.` id ` = ` ar `.` account_id `
 ```
 
 若 `tb_account` 表带有逻辑删除，那么其生成的 SQL 如下：
 
 ```sql
-SELECT * FROM `tb_account`
-    LEFT JOIN `tb_account` AS `a1`
-        ON `a1`.`id` = `tb_account`.`parent_id` AND `a1`.`is_delete` = ?
-    LEFT JOIN `tb_account` AS `a2`
-        ON `a2`.`id` = `tb_account`.`parent_id` AND `a2`.`is_delete` = ?
-WHERE `tb_account`.`id` >= ?
-  AND `tb_account`.`is_delete` = ?
+SELECT
+    ` ar `.` content `,
+    ` a1 `.` id `,
+    ` a2 `.` age `
+FROM
+    ` tb_article ` AS ` ar `
+    LEFT JOIN ` tb_account ` AS ` a1 ` ON (` a1 `.` id ` = ` ar `.` account_id `)

+    LEFT JOIN ` tb_account ` AS ` a2 ` ON (` a2 `.` id ` = ` ar `.` account_id `)
