Databricks-DA-Assoc Understanding the Databricks Platform Practice Question
Exhibit
{
"query_id": "q-12345",
"status": "FAILED",
"error": "Table 'sales_data' not found in catalog 'main' schema 'default'"
}Refer to the exhibit. An analyst receives this error when attempting to query a table. Which step should they take to fix this?
⚠ Common exam trap
Candidates often try to debug the code syntax or the table schema, ignoring the most common cause of 'table not found' errors in Unity Catalog: using an incomplete or incorrect three-level namespace.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the Catalog Explorer to confirm the correct fully qualified table name.
The error indicates a Namespace resolution issue. In Unity Catalog, objects must be referenced using the three-level namespace: catalog.schema.table. The error shows that the system is looking in 'main.default', but the table might be in a different catalog or schema. The analyst needs to verify the correct path using the Catalog Explorer to ensure they are referencing the qualified table name correctly in their SQL query.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the SQL Warehouse size to handle larger metadata lookups.
Why it's wrong here
The error is a 'Table not found' exception, which is a logic error related to object location, not a performance issue. Increasing the warehouse size will not help the system locate a table that is either missing or incorrectly referenced in the query. This misdiagnoses the root cause completely.
- ✓
Check the Catalog Explorer to confirm the correct fully qualified table name.
Why this is correct
Catalog Explorer allows users to navigate the data hierarchy and identify the exact path to a table. By finding the table in the explorer, the analyst can determine its actual catalog, schema, and name, ensuring they use the correct fully qualified path in their query to resolve the reference error.
- ✗
Switch the notebook language to Python to access the table.
Why it's wrong here
The issue is a missing object reference, which is independent of the programming language used. Switching to Python will not resolve a catalog resolution error. Whether using SQL or Python, the system still needs to resolve the table path within Unity Catalog's defined structure, which is currently failing.
- ✗
Request Workspace Admin privileges to access all system tables.
Why it's wrong here
Requesting admin privileges is unnecessary and violates the principle of least privilege. The issue is likely a simple pathing error, not a lack of administrative permissions. Most analysts have sufficient rights to query tables, but they must provide the correct three-level namespace to access them successfully in Unity Catalog.
