How do different SQL data types affect performance?
Different SQL data types can significantly impact performance due to factors like storage size, indexing, and retrieval speed.
Can you give examples of data types that are more efficient?
Sure! For instance, using INT instead of BIGINT can save space and improve performance for integer values.
What about string data types? Are there any best practices?
Yes, using VARCHAR instead of CHAR can be more efficient for variable-length strings, as it saves space.
How does indexing relate to data types?
Indexing can enhance performance, but the choice of data type affects the index's size and speed. Smaller data types generally lead to faster indexes.
