+title: "删除数据"

+
+删除数据是 TDengine 提供的根据指定时间段删除指定表或超级表中数据记录的功能，方便用户清理由于设备故障等原因产生的异常数据。
+注意：本功能只在企业版 2.6.0.0 及以后的版本中提供，如需此功能请点击下面的链接访问[企业版产品](https://www.taosdata.com/products#enterprise-edition-link)
+
+
+**语法：**
+
+```sql
+DELETE FROM [ db_name. ] tb_name [WHERE condition];
+```
+
+**功能：** 删除指定表或超级表中的数据记录
+
+**参数：**
+   
+- `db_name` ：  可选参数，指定要删除表所在的数据库名，不填写则在当前数据库中
+- `tb_name` ：  必填参数，指定要删除数据的表名，可以是普通表、子表，也可以是超级表。
+- `condition`： 可选参数，指定删除数据的过滤条件，不指定过滤条件则为表中所有数据，请慎重使用。特别说明，这里的where 条件中只支持对第一列时间列的过滤，如果是超级表，支持对 tag 列过滤。
+
+**特别说明：**
+      
+数据删除后不可恢复，请慎重使用。为了确保删除的数据确实是自己要删除的，建议可以先使用 `select` 语句加 `where` 后的删除条件查看要删除的数据内容，确认无误后再执行 `delete` 命令。      
+
+**示例：**
+    
+`meters` 是一个超级表，`groupid` 是 int 类型的 tag 列，现在要删除 `meters` 表中时间小于 2021-10-01 10:40:00.100 且 tag 列 `groupid` 值为 1 的所有数据，sql 如下：
+
+```sql
+delete from meters where ts < '2021-10-01 10:40:00.100' and groupid=1 ;
+```
+
+执行后显示结果为：
+
+```
+Deleted 102000 row(s) from 1020 table(s) (0.421950s)
+```
+
+表示从 1020 个子表中共删除了 102000 行数据

+sidebar_label: Delete Data
+description: "Delete data from table or Stable"
+title: Delete Data
+---
+
+TDengine provides the functionality of deleting data from a table or STable according to specified time range, it can be used to cleanup abnormal data generated due to device failure. Please be noted that this functionality is only available in Enterprise version, please refer to [TDengine Enterprise Edition](https://tdengine.com/products#enterprise-edition-link)
+
+
+**Syntax:**
+
+```sql
+DELETE FROM [ db_name. ] tb_name [WHERE condition];
+```
+
+**Description:** Delete data from a table or STable
+
+**Parameters:**
+   
+- `db_name`:   Optional parameter, specifies the database in which the table exists; if not specified, the current database will be used.
+- `tb_name`:  Mandatory parameter, specifies the table name from which data will be deleted, it can be normal table, subtable or STable.
+- `condition`: Optional parameter, specifies the data filter condition. If no condition is specified all data will be deleted, so please be cautions to delete data without any condition. The condition used here is only applicable to the first column, i.e. the timestamp column. If the table is a STable, the condition is also applicable to tag columns.
+
+**More Explanations:**
+      
+The data can't be recovered once deleted, so please be cautious to use the functionality of deleting data. It's better to firstly make sure the data to be deleted using `select` then execute `delete`.       
+
+**Example:**
+    
+`meters` is a STable, in which `groupid` is a tag column of int type. Now we want to delete the data older than 2021-10-01 10:40:00.100 and `groupid` is 1.  The SQL for this purpose is like below:
+
+```sql
+delete from meters where ts < '2021-10-01 10:40:00.100' and groupid=1 ;
+```
+
+The output is:
+
+```
+Deleted 102000 row(s) from 1020 table(s) (0.421950s)
+```
+
+It means totally 102,000 rows of data have been deleted from 1,020 sub tables.
