The window function, like an aggregate function, is an aggregate calculation of the set of rows. It is used to define a window for a row (where the window refers to the collection of rows to be manipulated), which operates on a set of values, does not need to group the data using the GROUP BY clause, and can return both the column and the aggregate column of the underlying row in the same row. Anyway, I und

Label: A function is a collection in which each element is a two-tuple or multivariate group. For example F = {(x, y) | X∈r y∈r y = 2x}, g = {(x, y, z) | (x, Y, z) ∈r3 z = 2x + 3y}, symbols F and G refer to two functions. A relationship instance is a collection, and each element of it is a tuple. You can see that relationship instances and functions are almost the same concept, except that each element of a fun

As we all know, in C #, it is easy to use the split method to divide a string into an array with the specified characters, but in T-SQL, it is .... In my project, there are the following applications: Read a batch of data in batches, then process the data in each row. After processing, return the processed ID and the failed ID to the database, this involves a batch update problem. Do you want to write IDs one by one for batch processing and update the
