Implementation (aggregate function), SQLServer Sometimes you may need to convert rows to columns (that is, using the column value as the column name). I usually use the CASE END + aggregate function. As follows: Declare @ t table (StudentName nvarchar (20), Subject nvarchar (20), Score int) Insert into @ t (StudentName, Subject, Score) values ('student ', 'Chinese', 80); Insert into @ t (StudentName, Subjec

C # use Aggregate, Directly run the Code: IEnumerable View Code Debugging, the first call, found that sum and index respectively take the list of 1st and 2nd values: F5 next, we found that the index was added to sum (sum + = index), then index took the next value, and accumulated to sum. Repeat this step until the value in the list is obtained: The final calculation result is 65. The other two overload functions: Int all = list.

The MySQL aggregate function provides addition, average, minimum, and maximum, but not multiplication. Here we use the existing MYSQL GROUP_CONCAT function to implement aggregation multiplication.

Multiline functions are also Aggregate functions and composite functions. The parameter is an array and the data size is the number of records. This array is not an array of common advanced languages, but a virtual array, when the number of records is large, data is written to the hard disk, and only imag
