Mastering SQL Case Sensitivity and Conventions for Improved Code Quality and Security
Understanding SQL Case Sensitivity and Conventions Introduction to SQL Case Insensitivity SQL is often misunderstood as case-sensitive, but this is not entirely accurate. While SQL functions are indeed case-insensitive, the language itself does have some nuances when it comes to case sensitivity. In most databases, SQL functions such as DATE() or NOW() are evaluated based on the exact text specified, regardless of capitalization. This means that both DATE(col_1) and date(col_1) would be treated as identical, returning the same date value.
