T-SQL, which is used in Microsoft SQL Server, has many built-in functions. Understanding T-SQL functions is essential to anyone who wants to work with SQL Server. Data analysts use these functions to prepare accurate reports. SQL developers and software developers use them to write concise and readable queries. In both cases, T-SQL functions make it easier to get the right results!

The course offers 150 interactive exercises. You’ll read clear explanations on what each SQL Server function does, and then you’ll write your own T-SQL queries to solve realistic problems. The practice exercises are fun and engaging, and they’ll give you confidence in using T-SQL.
