The UNION SQL clause is used to combine the results of two or more SELECT statements. However, it cannot be used directly with the DELETE or UPDATE clauses. Therefore, the correct answer to your question is "SELECT clause only."

Here’s a brief explanation of the reasoning:

1. **UNION with SELECT**: The UNION operator is designed to combine the results of multiple SELECT queries, allowing you to retrieve data from different tables or query results in a consolidated format.

2. **UNION with DELETE or UPDATE**: These clauses modify data rather than retrieving it. The SQL syntax and operations of DELETE and UPDATE do not support the use of UNION directly because they do not generate result sets in the way SELECT statements do.

Based on this understanding, it is clear that the correct option is **"SELECT clause only."**
