Ensure Consistency: All queries in a union must return the same number of columns, and the data types must match. This is a fundamental requirement of the UNION operation. 2. Simplify Your Queries: Simpler searches tend to run faster. If possible, try to simplify your queries. For example, instead of using a UNION, you might be able to use an IN clause to achieve the same result. For instance,

SELECT ID, Type FROM Transaction WHERE ID IN (40330, 40771)

. 3. Use Asynchronous Methods: If your query is complex and involves a large number of joins, you might be able to refactor it into discrete independent units that you can run asynchronously and then merge the results afterwards. This can be particularly useful when querying large sets of transactions. For example, you could break the query into chunks by year or quarter, run them through a Promise.all, then combine the results afterwards. 4. Avoid Unsupported Operations: Some operations, such as UNION, might not be supported in all contexts. For example, it appears that SuiteTalk REST's SuiteQL might not support UNION. In such cases, you might need to find alternative ways to achieve your goal, such as running the UNION query as a SuiteLet. Remember, the key to optimizing queries is to ensure they are as simple and efficient as possible. This often involves breaking down complex queries into simpler parts, running these parts independently, and then combining the results.
