SQL agent with memory
Configured with Agent, Chat Trigger, Compression, HTTP Request, and additional nodes. Review the connections and setup before adapting this template.
Node categories in this workflow
- Data store
- AI & models
- Trigger
- Web / API
- Transform
- Files / media
Icons describe general node roles, inferred from node types. Inspect the parameters for the configured action.
Drag to pan; use + and − to zoom. Reconstructed from the exported node positions; nothing runs here. Dashed lines represent non-main connections. Full node names and notes appear below.
How it works
The exported workflow contains the following configured nodes. Their connections are shown above; inspect the JSON for the complete logic, expressions, and external actions.
| Node | Category | Type | Operation |
|---|---|---|---|
| Window Buffer Memory | Data store | Memory Buffer Window | See node parameters |
| OpenAI Chat Model | AI & models | OpenAI Chat Model | See node parameters |
| When clicking "Test workflow" | Trigger | Manual Trigger | See node parameters |
| Get chinook.zip example | Web / API | HTTP Request | See node parameters |
| Extract zip file | Transform | Compression | See node parameters |
| Save chinook.db locally | Files / media | Read Write File | write |
| Load local chinook.db | Files / media | Read Write File | See node parameters |
| Combine chat input with the binary | Transform | Edit Fields | See node parameters |
| AI Agent | AI & models | Agent | See node parameters |
| Chat Trigger | Trigger | Chat Trigger | See node parameters |
Setup
- Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
- Connect your own credentials through n8n’s credential store. Replace
REPLACE_WITH_*values with your resource identifiers. - Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
- Run with synthetic data and harmless destinations. Enable triggers only after checking the actual outputs.
Requirements
An n8n instance with the listed node types and compatible versions. Service-connected workflows may require accounts, credentials, or paid APIs.
Credential types declared in the source

This section:
- downloads the example zip file from https://www.sqlitetutorial.net/sqlite-sample-database/
- extracts the archive (it contains only a single file)
- saves the extracted
chinook.dbSQLite database locally
Now you can use chat to "talk" to your data!
On every chat message:
On every chat message:
- the local SQLite database is loaded
- JSON from Chat Trigger is combined with SQLite binary data
LangChain SQL Agent can make several queries before producing the final answer.
LangChain SQL Agent can make several queries before producing the final answer.
Try these examples:
- "Please describe the database". This input usually requires just 1 query + an extra observation to produce a final answer.
- "What are the revenues by genre?". This input will launch a series of Agent actions, because it needs to make several queries.
The final answer is stored in the memory and will be recalled on the next input from the user.

Purpose and structure
This folder contains the SQL agent with memory workflow. Its executable nodes use agent, chatTrigger, compression, httpRequest, lmChatOpenAi, manualTrigger, memoryBufferWindow, readWriteFile, set. The table and connection map below are derived from the JSON, not an inferred guarantee of behavior.
Setup
Import inactive. Configure your own credentials and replace REPLACE_WITH_* values. Review external destinations and Code nodes before running.
Entry points
When clicking "Test workflow", Chat Trigger
Verification
Sanitized source candidate; not runtime-tested. This overview is generated from node metadata. Read the folder README for the connection map, credential types, and license.
