## SQL删除语句
|
||
|
||
要删除表中的记录，请使用`DELETE`语句。
|
||
|
||
小心。您可以删除表格的所有记录或只删除一些记录。使用`WHERE`条件指定要删除的记录。语法是：
|
||
|
||
```sql
|
||
DELETE FROM table_name
|
||
WHERE condition;
|
||
```
|
||
|
||
下面是从表中删除Id 3记录的示例：
|
||
|
||
```sql
|
||
DELETE FROM Person
|
||
WHERE Id = 3;
|
||
```
|
||
|
||
使用DELETE删除给定表中的所有记录
|
||
|
||
```sql
|
||
DELETE * FROM Person
|
||
;
|
||
```
|
||
|
||
或者，根据您的RDBMS，您可以使用TRUNCATE TABLE语句删除表中的所有记录，并且根据您的RDBMS可能允许或不允许回滚。 DELETE是DML，TRUNCATE是DDL。
|
||
|
||
```sql
|
||
TRUNCATE TABLE Person;
|
||
|
||
``` |
