<!-- Answer --> The issue you're encountering seems to be related to schema resolution when saving a dashboard in Superset, particularly when using Jinja templating and the StarRocks database. Here are a few points to consider: 1. **Schema Resolution**: Superset uses the `extract_tables_from_statement` function to resolve schema and table references. This function extracts table references by parsing the SQL statement's abstract syntax tree (AST) and considers various SQL constructs. It ensures that the correct schema is used when referencing tables <sup>[[1]](https://github.com/apache/superset/blob/master/superset/sql/parse.py)</sup><sup>[[2]](https://github.com/apache/superset/blob/master/superset/db_engine_specs/starrocks.py)</sup>. 2. **Jinja Templating**: When using Jinja templating, Superset processes the SQL text to substitute Jinja blocks and variables before parsing it to extract table references. This process should ensure that the correct schema is applied, but issues can arise if the Jinja context or variables are not correctly set up <sup>[[3]](https://github.com/apache/superset/blob/master/superset/sql_parse.py)</sup><sup>[[4]](https://github.com/apache/superset/blob/master/tests/unit_tests/sql_parse_tests.py)</sup>. 3. **Version 4.1.2 Changes**: In Superset version 4.1.2, there was a fix related to schema handling, allowing the clearing of schema and catalog in SQL Lab. This might be relevant if there are discrepancies between the schema used in SQL Lab and when saving dashboards <sup>[[5]](https://github.com/apache/superset/blob/master/CHANGELOG/4.1.2.md)</sup>. 4. **StarRocks Specifics**: Superset interacts with StarRocks databases using the `sqlglot` library with the `STARROCKS` dialect. Ensure that the connection parameters and schema settings are correctly configured for StarRocks <sup>[[2]](https://github.com/apache/superset/blob/master/superset/db_engine_specs/starrocks.py)</sup>. Given these points, you might want to verify the following: - Ensure that the Jinja context is correctly set up and that the variables used in your queries are resolving to the expected schema. - Check if there are any discrepancies in schema settings between SQL Lab and the dashboard save operation. - Review the Superset configuration for any custom Jinja context additions that might affect schema resolution. If the issue persists, it might be helpful to further investigate the specific Jinja templates and variables used in your queries to ensure they are correctly resolving to the intended schema. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
