# Edit Database

> Edit a database hosted on Square Cloud, changing name and/or memory.

<ParamField header="Authorization" type="string" placeholder="API Key" required>
  The API key for your account. You can find this in your [account settings](https://squarecloud.app/en/account/security).
</ParamField>

Updates a database's display name and/or its allocated memory without recreating the container or rotating its credentials, connection URL and port stay the same. At least one of `name` or `ram` must be present in the request body.

Changing `ram` is applied live against the database's cluster; it fails if the new value is invalid for the plan or engine. This does not restart the database. To check whether a memory change is reflected, see [Get Database Info](/en/api-reference/endpoint/databases/info) or [Get Database Status](/en/api-reference/endpoint/databases/status). Rate limited to 1 update every 5 seconds per user.

### Parameters

<ParamField path="database_id" type="string" placeholder="Database ID" required>
  The ID of the database.
</ParamField>

<ParamField body="name" type="string" placeholder="database name">
  The name of the database. 1–32 characters — letters, numbers, underscores (`_`), hyphens (`-`) and spaces — and must include at least one letter, number or underscore.
</ParamField>

<ParamField body="ram" type="int" placeholder="RAM(in MB)">
  The amount of RAM to allocate, in megabytes. Minimums: Redis 512 MB, MongoDB and PostgreSQL 1024 MB.
</ParamField>

### Response

<ResponseField name="status" type="string">
  Indicates whether the call was successful.. `success` if successful, `error` if not.
</ResponseField>

  ```json theme={null}
  {
    "status":"success"
  }
