Is SQL case-sensitive? If yes what could be the effect of it on the database?
What are the implications and considerations required to follow during the case if SQL case sensitive? Explain how the case sensitivity can affect the data considering retrieval, comparisons, and sorting.
Yes, the SQL case is sensitive, however, the case sensitivity depends upon which database management system you are using. Some systems are case-sensitive by default whereas some may have included case-sensitive by changing the setting. Here are the impacts given if the case of SQL case sensitivity:-
Data retrieval and comparison
Consider a scenario where there is an analogy given
SELECT * FROM users WHERE name = JohnIn this above scenario, John would not be matched if the database is case-sensitive. It means the queries of SQL differentiate between lowercase and uppercase if the database is case-sensitive.
Sorting If the database is case sensitive then the sorting operations could yield different conclusions. For instance, a case-sensitive database would sorted differently from ‘apple’ or “APPLE” for query APPLE.
Therefore it is important to understand the case sensitivity settings for ensuring correct process regarding accurate data retrieval, comparison, and sorting within SQL operation.
