SQL interview questions handling case sensitive with charindex in SQL Server

In an SQL interview, a common question might relate to handling case sensitivity with the `CHARINDEX()` function in SQL Server. When working with text data, it's essential to be aware of case sensitivity, as SQL Server's `CHARINDEX()` is case-insensitive by default. To perform a case-sensitive search, you can apply a binary collation to the search operation. By using this method, the function will differentiate between lowercase and uppercase characters when searching for a substring within a string.

`CHARINDEX()` in SQL Server is a function that searches for the position of a substring within a string. It returns the starting position of the substring, or 0 if not found. It's often used for string manipulation and searching operations.
