||||
SHOW QUERY PROFILE
|
||||
|
||||
### Description
|
||||
|
||||
This statement is used to view the tree profile information of the query operation,this function requires the user to open profile settings.
|
||||
Before versions 0.15, perform the following settings:
|
||||
|
||||
```sql
|
||||
SET is_report_success=true;
|
||||
```
|
||||
|
||||
For versions 0.15 and later, perform the following settings:
|
||||
|
||||
```sql

|
||||
```
|
||||
|
||||
grammar:
|
||||
|
||||
```sql
|
||||
show query profile "/";
|
||||
```
|
||||
This command will list the profiles of all currently saved query operations.
|
||||
|
||||
```sql
|
||||
show query profile "/queryId"\G
|
||||
show query profile "/queryId/fragment_id/instance_id"\G
|
||||
```
|
||||
Get the tree profile information of the specified query ID,Return to profile simple tree.Specify fragment_ ID and instance_ ID returns the corresponding detailed profile tree.
|
||||
|
||||
|
||||
### Example
|
||||
|
||||
1. List all query Profile
|
||||
|
||||
```sql
|
||||
mysql> show query profile "/";
|
||||
+-----------------------------------+------+-------------------------+--------------------+-----------+---------------------+---------------------+-----------+------------+
|
||||
| QueryId | User | DefaultDb | SQL | QueryType | StartTime | EndTime | TotalTime | QueryState |
|
||||
+-----------------------------------+------+-------------------------+--------------------+-----------+---------------------+---------------------+-----------+------------+
|
||||

|
||||
+-----------------------------------+------+-------------------------+--------------------+-----------+---------------------+---------------------+-----------+------------+
|
||||
1 row in set (0.00 sec)
|
||||
```
|
||||
|
||||
2. List the query profile of the specified queryid
|
||||
|
||||
```sql
|
||||
mysql> show query profile "/327167e0db4749a9-adce3b3d770b2bb1"\G

### Name
|
||||
|
||||
SHOW QUERY PROFILE
|
||||
|
||||
### Description
|
||||
|
||||
该语句是用来查看QUERY操作的树状Profile信息,该功能需要用户打开 Profile 设置,0.15 之前版本执行下面的设置:
|
||||
|
||||
```sql
|
||||
SET is_report_success=true;
|
||||
```
|
||||
|
||||
0.15 及之后的版本执行下面的设置:
|
||||
|
||||
```sql
|
||||
SET [GLOBAL] enable_profile=true;
|
||||
```
|
||||
|
||||
语法:
|
||||
|
||||
```sql
|
||||
show query profile "/";
|
||||
```
|
||||
这个命令会列出当前保存的所有query操作的 Profile 。
|
||||
|
||||
```sql
|
||||
show query profile "/queryId"\G;
|
||||
show query profile "/queryId/fragment_id/instance_id";
|
||||
```
|
||||
获取指定query id树状profile信息,返回profile 简易树形图。指定fragment_id和instance_id则返回对应的详细profile树形图。
|
||||
|
||||
|
||||
### Example
|
||||
|
||||
1. 列出所有的 query Profile
|
||||
|
||||
```sql
|
||||
mysql> show query profile "/";
|
||||
+-----------------------------------+------+-------------------------+--------------------+-----------+---------------------+---------------------+-----------+------------+
|
||||
| QueryId | User | DefaultDb | SQL | QueryType | StartTime | EndTime | TotalTime | QueryState |

||||
+-----------------------------------+------+-------------------------+--------------------+-----------+---------------------+---------------------+-----------+------------+
|
||||
| 327167e0db4749a9-adce3b3d770b2bb1 | root | default_cluster:test_db | select * from test | Query | 2022-08-09 10:50:09 | 2022-08-09 10:50:09 | 19ms | EOF |
|
||||
+-----------------------------------+------+-------------------------+--------------------+-----------+---------------------+---------------------+-----------+------------+
|
||||
1 row in set (0.00 sec)
|
||||
```
|
||||
|
||||
2. 列出指定QueryId的 query Profile
|
||||
|
||||
```sql
|
||||
mysql> show query profile "/327167e0db4749a9-adce3b3d770b2bb1"\G
