# Update SQL draft version

Modifying the SQL content saved in the draft version will not execute the SQL. The finalized version cannot be modified.

```text
POST https://moi.matrixorigin.cn/newmoi/workbook/version/update
```

## Preparation before calling

Prepare your personal access token, workspace ID, SQL save record ID, and draft version ID with update permissions. `$AI_STUDIO_API_KEY` is the personal access token used as the value of the `X-API-Key` request header; `$WORKSPACE_ID` is the target workspace ID used as the value of the `X-Workspace-ID` request header. You can first [View saved SQL version](list-workbook-versions.md) to confirm the version status.

`$WORKBOOK_ID` in the example below is the ID of the SQL saved record and `$VERSION_ID` is the version ID with status `draft`.

## Request body

Replace caller-specific values in the example with actual values.
