DQL Query¶
Switch Query Method
Simple query and DQL query can be switched by clicking the button. If the query cannot be parsed or is incompletely parsed after switching:
- If no actions are taken in the simple query mode, the previous DQL query statement will be displayed when switching back to DQL query;
- If the query statement is adjusted in the simple query mode, it will be parsed according to the latest simple query when switching back to DQL query.
After switching to DQL mode, you can manually enter DQL statements for chart queries. A chart supports running multiple DQL queries simultaneously.
Note
Using wildcards or regular expressions for searches may slow down or crash the system. It is recommended to preprocess data through Pipeline first, then perform precise filtering to improve performance and stability.
