![]() In such cases, alternative approaches like CASE statements may offer more flexibility and control. No control over evaluation order: Its fixed argument evaluation order represents a limitation in specific scenarios where different logic is required.Potential impact on query readability: As the number of arguments increases or when combined with other conditional logic, the query becomes longer, making it more difficult to read.If you have to perform operations or substitutions on multiple NULL values in a single query, you will need more complex queries. Limited to the first non-NULL value: This behavior is suitable for scenarios where you only need to replace a single NULL value.In the case of unsupported data types, the query will fail with ERROR: COALESCE types and cannot be matched. When required, it automatically performs implicit type conversions. Flexible with data types: It supports several data types, including strings and numbers.Plus, different frontends may address missing data in different ways, causing inconsistencies. This is generally faster and less cumbersome than doing it at the application level. ![]()
