Error: No Active Warehouse Selected in the Current Session

Issue

In Fivetran, the following error appears:

No active warehouse selected in the current session. Select an active warehouse with the 'use warehouse' command.

Connector: Snowflake

To resolve this issue, do the following:

Log in to the Snowflake account that contains the target warehouse.
Verify that the warehouse is active by running the following command:
```
SHOW WAREHOUSES;
```
Find the applicable warehouse and confirm that the STATE is RUNNING.
Confirm the Fivetran user's default warehouse by running:
```
show users like '<fivetran_user>';
```
Check the warehouse listed in the DEFAULT_WAREHOUSE column.
If the default warehouse is incorrect or the case doesn’t match, set the correct default warehouse by running the following commands:
```
USE ROLE SECURITYADMIN;
ALTER USER <fivetran_user> SET DEFAULT_WAREHOUSE = <UPPERCASE_WAREHOUSE_NAME>;
```
Snowflake stores unquoted names in uppercase. Ensure the warehouse name matches this case.

This issue occurs when the default warehouse is suspended, misconfigured, or its name doesn't match the Snowflake case conventions.
