Jan 23, 2017· For doing operations on data sql has many built-in functions, they are categorised in two categories and further sub-categorised in different seven functions under each category The categories are: Aggregate functions: These functions are used to do operations from the values of the column and a single value is returned AVG() COUNT() FIRST .

Another thing to note is that again the null values will be ignored with the MIN and MAX functions If you are just using this function, just be aware that when the null values are ignored and when they aren't Finally, we have the SUM aggregate function Again, you can use this in a similar fashion as with the other aggregate functions

I could probably use the MIN/MAX aggregate functions, but they would likely make the query even slower I know that, in MySQL, you can select a column that doesn't appear in the GROUP BY clause, and the DB engine will return any row value at random for that column Is something like that doable in T-SQL?

Nov 10, 2011· The alternative is that a function is treated as interpreted code, and invoking it from the main body of code requires a jump to a different code block to execute the function The biggest drawback of SQL Server functions is that they may not be automatically inlined For a scalar function that operates on multiple rows, SQL Server will execute .
