在使用命令行客户端或HTTP客户端时，你可以将具体的查询语句与数据分开发送。更多具体信息，请参考«[客户端](../../interfaces/index.md#interfaces)»部分。
### 限制 {#constraints}
如果表中有一些[限制](../../sql-reference/statements/create/table.md#constraints),，数据插入时会逐行进行数据校验，如果这里面包含了不符合限制条件的数据，服务将会抛出包含限制信息的异常，这个语句也会被停止执行。
### 使用`SELECT`的结果写入 {#insert_query_insert-select}
``` sql
@ -96,6 +100,66 @@ INSERT INTO [db.]table [(c1, c2, c3)] SELECT ...
系统不支持的其他用于修改数据的查询：`UPDATE`, `DELETE`, `REPLACE`, `MERGE`, `UPSERT`, `INSERT UPDATE`。
但是，您可以使用 `ALTER TABLE ... DROP PARTITION`查询来删除一些旧的数据。
如果 `SELECT` 查询中包含了 [input()](../../sql-reference/table-functions/input.md) 函数，那么 `FORMAT` 必须出现在查询语句的最后。
如果某一列限制了值不能是NULL，那么插入NULL的时候就会插入这个列类型的默认数据，可以通过设置 [insert_null_as_default](../../operations/settings/settings.md#insert_null_as_default) 插入NULL。
### 从文件向表中插入数据 {#inserting-data-from-a-file}
``` sql
INSERT INTO [db.]table [(c1, c2, c3)] FROM INFILE file_name [COMPRESSION type] FORMAT format_name
```
使用上面的语句可以从客户端的文件上读取数据并插入表中，`file_name` 和 `type` 都是 `String` 类型，输入文件的[格式](../../interfaces/formats.md) 一定要在 `FORMAT` 语句中设置。
支持读取压缩文件。默认会去读文件的拓展名作为文件的压缩方式，或者也可以在 `COMPRESSION` 语句中指明，支持的文件压缩格式如下：`'none'`， `'gzip'`， `'deflate'`， `'br'`， `'xz'`， `'zstd'`， `'lz4'`， `'bz2'`。
这个功能在 [command-line client](../../interfaces/cli.md) 和 [clickhouse-local](../../operations/utilities/clickhouse-local.md) 是可用的。
**样例**
```bash
echo 1,A > input.csv ; echo 2,B >> input.csv
clickhouse-client --query="CREATE TABLE table_from_file (id UInt32, text String) ENGINE=MergeTree() ORDER BY id;"
clickhouse-client --query="INSERT INTO table_from_file FROM INFILE 'input.csv' FORMAT CSV;"
clickhouse-client --query="SELECT * FROM table_from_file FORMAT PrettyCompact;"
```
结果:
```text
┌─id─┬─text─┐
│ 1 │ A │
│ 2 │ B │
└────┴──────┘
```
### 插入表函数 {#inserting-into-table-function}
数据可以通过 [table functions](../../sql-reference/table-functions/index.md) 方法插入。
``` sql
INSERT INTO [TABLE] FUNCTION table_func ...
```
**例如**
可以这样使用[remote](../../sql-reference/table-functions/index.md#remote) 表函数:
``` sql
CREATE TABLE simple_table (id UInt32, text String) ENGINE=MergeTree() ORDER BY id;
INSERT INTO TABLE FUNCTION remote('localhost', default.simple_table)
VALUES (100, 'inserted via remote()');
SELECT * FROM simple_table;
```
结果:
``` text
┌──id─┬─text──────────────────┐
│ 100 │ inserted via remote() │
└─────┴───────────────────────┘
```
### 性能的注意事项 {#xing-neng-de-zhu-yi-shi-xiang}
在进行`INSERT`时将会对写入的数据进行一些处理，按照主键排序，按照月份对数据进行分区等。所以如果在您的写入数据中包含多个月份的混合数据时，将会显著的降低`INSERT`的性能。为了避免这种情况：

- 数据总是被实时的写入。
- 写入的数据已经按照时间排序。
也可以异步的、小规模的插入数据，这些数据会被合并成多个批次，然后安全地写入到表中，通过设置[async_insert](../../operations/settings/settings.md#async-insert)，可以使用异步插入的方式，请注意，异步插入的方式只支持HTTP协议，并且不支持数据去重。
