Schema not found

Last updated on Oct 26, 2022
Applies To Snowflake Destination
Error Message Text(s) Could not find schema ‘{schema}’. Hint: Snowflake schema names are case-sensitive.

Potential Causes

  • Incorrect spelling or case mismatch between actual schema name and the schema name provided in Hevo.

  • The schema does not exist.

  • The user does not have sufficient permissions to access the schema.

Suggested Action(s)

  • Verify that the schema name spelling is correct and is in upper case.

  • Verify that the schema exists, and the user has sufficient permissions to access the schema. To do this:

    1. Log in to the Snowflake instance.

    2. Click the Expand chevron (drop-down icon) at the top left.

    3. From the Switch Roles list, select the role which you want to use.

      Select a role

    4. Click Data, and then click Databases.

      Click Databases

    5. In the Databases page, select the database for which you want to view the schema.

      Select the database

    6. Click Schemas.

      Click Schemas

    7. Verify that the schema exists.

      Select the schema

    8. Click on the schema, and in the Schema Details tab, verify that Hevo has the CREATE SCHEMA, MODIFY, MONITOR, and USAGE permissions for the schema.

      Check schema permissions

    9. If the schema does not exist, or the user does not have the required permissions, you need to create the schema with the required permissions, or grant the required permissions on the pre-existing schema for Hevo to access your data, using the following steps:

      1. In the left navigation pane, click Worksheets, and then click + Worksheet.

        Add Worksheet

      2. Paste the following script in the worksheet. You can use this script to either create a new schema with the required permissions, or grant permissions to a pre-existing schema. Keeping your privacy in mind, the script grants only the bare minimum permissions required by Hevo to load the data in your Destination.

        Note: The values for database_name, role_name , and schemaName must be in upper case.

        -- Variables for role / schema / database (needs to be uppercase for objects)\
        set database_name = 'HEY'; // Replace "HEY" with the role to which you want to grant access to
        set schemaName = 'HELLO_SCHEMA'; // Replace "HELLO_SCHEMA" with the schema name that you want to grant access to
        set role_name = 'ACCOUNTADMIN'; // Replace "ACCOUNTADMIN" with the role that you want to grant access to
        set db_schema = concat($database_name, '.', $schemaName);
        use role accountadmin;
        CREATE SCHEMA IF not exists identifier($db_schema);
        GRANT USAGE, MONITOR, CREATE TABLE, CREATE EXTERNAL TABLE, MODIFY ON SCHEMA identifier($db_schema) TO ROLE identifier($role_name);
      3. You can specify a new schema name to create it now, or specify the name of a pre-existing schema to grant the required permissions on it in line 3 of the script, for Hevo to load data into it.

      4. Press CMD+return (Mac) or CTRL + Enter (Windows) to run the script.

      5. Once the script is successfully executed, you can use the credentials from lines 2-4 of the script to connect your Snowflake warehouse to Hevo.
