<!-- Answer -->
To address the issue where a user with the necessary permissions cannot
query a database in SQL Lab and receives an error indicating a failure to
execute the SQL query, let's go through a detailed checklist and some potential
solutions:
### Checklist and Potential Solutions
1. **Verify Permissions**:
Ensure that the user has the following permissions:
```python
def test_sql_lab_permissions(self):
sql_lab_set = get_perm_tuples("sql_lab")
self.assertEqual(
sql_lab_set,
{
("can_activate", "TabStateView"),
("can_csv", "Superset"),
("can_delete_query", "TabStateView"),
("can_delete", "TabStateView"),
("can_execute_sql_query", "SQLLab"),
("can_export", "SavedQuery"),
("can_export_csv", "SQLLab"),
("can_get", "TabStateView"),
("can_get_results", "SQLLab"),
("can_migrate_query", "TabStateView"),
("can_sqllab", "Superset"),
("can_sqllab_history", "Superset"),
("can_put", "TabStateView"),
("can_post", "TabStateView"),
("can_write", "SavedQuery"),
("can_read", "Query"),
("can_read", "Database"),
("can_read", "SQLLab"),
("can_read", "SavedQuery"),
("menu_access", "Query Search"),
("menu_access", "Saved Queries"),
("menu_access", "SQL Editor"),
("menu_access", "SQL Lab"),
},
)
```
Specifically, ensure the user has `can_execute_sql_query` for `SQLLab`
and `can_read` for `Database`.
2. **Database Connection Configuration**:
Verify that the database connection is properly configured. Ensure that
the connection string and credentials are correct and that the database is
accessible from Superset.
3. **Check SQL Query Validity**:
Ensure that the SQL query being executed is valid. The error message
suggests a potential issue with the query or permissions. Verify that the table
`main.bart_lines` exists and that the user has access to it.
4. **Review Logs for Specific Errors**:
Check the Superset logs for any specific error messages that might
provide more insight into the problem. Look for any security-related errors or
issues with the database connection.
5. **Security Restrictions**:
If the error message indicates a security access issue, it might be
related to the `QueryIsForbiddenToAccessException` in
`superset/sqllab/exceptions.py`. This exception is raised when a query is
forbidden to access due to security reasons. The error message will include a
reason and possibly a suggestion to help resolve the issue:
```python
QUERY_IS_FORBIDDEN_TO_ACCESS_REASON_MESSAGE = "can not access the query"
class QueryIsForbiddenToAccessException(SqlLabException):
def __init__(
self,
sql_json_execution_context: SqlJsonExecutionContext,
exception: Exception | None = None,
) -> None:
super().__init__(
sql_json_execution_context,
SupersetErrorType.QUERY_SECURITY_ACCESS_ERROR,
QUERY_IS_FORBIDDEN_TO_ACCESS_REASON_MESSAGE,
exception,
)
```
6. **Frontend Actions**:
Ensure that the frontend actions related to SQL Lab are functioning
correctly. The `runQuery` function in
`superset-frontend/src/SqlLab/actions/sqlLab.js` handles the execution of SQL
queries from the frontend and includes error handling for various scenarios,
such as CSRF token issues and session timeouts:
```js
export function runQuery(query) {
return function (dispatch) {
dispatch(startQuery(query));
const postPayload = {
client_id: query.id,
database_id: query.dbId,
json: true,
runAsync: query.runAsync,
catalog: query.catalog,
schema: query.schema,
sql: query.sql,
sql_editor_id: query.sqlEditorId,
tab: query.tab,
tmp_table_name: query.tempTable,
select_as_cta: query.ctas,
ctas_method: query.ctas_method,
templateParams: query.templateParams,
queryLimit: query.queryLimit,
expand_data: true,
};
const search = window.location.search || '';
return SupersetClient.post({
endpoint: `/api/v1/sqllab/execute/${search}`,
body: JSON.stringify(postPayload),
headers: { 'Content-Type': 'application/json' },
parseMethod: 'json-bigint',
})
.then(({ json }) => {
if (!query.runAsync) {
dispatch(querySuccess(query, json));
}
})
.catch(response =>
getClientErrorObject(response).then(error => {
let message =
error.error ||
error.message ||
error.statusText ||
t('Unknown error');
if (message includes('CSRF token')) {
message = t(COMMON_ERR_MESSAGES.SESSION_TIMED_OUT);
}
dispatch(queryFailed(query, message, error.link, error.errors));
}),
);
};
}
```
7. **Superset Security Manager**:
Ensure that the user has the appropriate permissions set up in the
`SupersetSecurityManager` class in `superset/security/manager.py`, particularly
for accessing databases and executing SQL queries. The `can_access` method and
related methods in this class are crucial for determining if a user has the
necessary permissions to perform certain actions.
### Additional Steps
If the above steps do not resolve the issue, please provide the exact error
messages from the Superset logs. This will help in diagnosing the problem more
accurately. Additionally, ensure that there are no network issues or firewall
rules blocking access to the database.
By following these steps, you should be able to identify and resolve the
issue preventing the user from querying the database in SQL Lab.
