# Check data plane version in self-hosted deployments

export const plans_0 = "Any"

export const deployments_0 = "Self-hosted"

export const data_plane_version_0 = undefined

export const use_case_0 = undefined

<Note>
  **Applies to:**

  * Plan - {plans_0}
  * Deployment - {deployments_0}
  * {data_plane_version_0}
  * {use_case_0}
</Note>

## Summary

**Goal:** Check your self-hosted data plane version to troubleshoot SQL query syntax errors and feature availability.

## Configuration Steps

### Step 1: Navigate to the API URL configuration page

Go to the following URL pattern, replacing the placeholders with your organization and project names:

```text theme={"theme":{"light":"github-light","dark":"github-dark-dimmed"}}
https://www.braintrust.dev/app/[ORGNAME]/p/[PROJECTNAME]/configuration/org/api-url

```

### Step 2: View the data plane version

The data plane version is displayed on this configuration page.

### Step 3: Verify SQL support availability

Check the data plane changelog to confirm your version supports plain SQL queries (SELECT and WITH statements).

## Common Issues

Plain SQL queries may fail if your data plane version predates SQL support. Braintrust auto-detects SQL vs BTQL by checking if queries start with `SELECT` or `WITH`. If you encounter syntax errors with valid SQL, upgrade your data plane version.
