SQL Interview questions find duplicate rows values using case sql server
In a SQL Server interview, you might be asked to identify duplicate rows using a `CASE` statement. This involves using a combination of functions to assess if a row has duplicates based on specific criteria. The `CASE` statement allows conditional evaluation, enabling the distinction of duplicate and non-duplicate rows. Interviewees should demonstrate a clear understanding of SQL functions and logical constructs to effectively handle such scenarios and highlight their problem-solving skills within a relational database context.
