+## Dynamic query embed syntax
+
+The syntax of the content block dynamic query embed is:
+
+```sql
+!{{ SELECT * FROM blocks WHERE content LIKE '%content block%' }}
+```
+
+It needs to be used on its own line. The script syntax used is SQL. For details, please refer to ((20201117103851-gx21lz6 "here")).
+
+### Example
+
+* Query list items that contain `content block`:
+
+  ```sql
+  !{{ SELECT * FROM blocks WHERE content LIKE '%content block%' AND type = 'NodeListItem' }}
+  ```
+* The query content contains both `content block` and `reference` paragraph blocks:
+
+  ```sql
+    !{{ SELECT * FROM blocks WHERE content LIKE'%content block%' AND content LIKE'%reference%' }}
+  ```
+* The query content contains title blocks of both `content block` and `embed`, and the first 2 items are selected in descending order of time:
+
+  ```sql
+  !{{ SELECT * FROM blocks WHERE (content LIKE '%content block%' AND content LIKE '%embed%') AND type ='NodeHeading' ORDER BY block_id DESC LIMIT 4 }}
+  ```
