Join Martin Guidry for an in-depth discussion in this video Returning data using cursors, part of SQL Server: Triggers, Stored Procedures, and Functions.
Next, I'd like to talk about returning data from a stored procedure using a cursor.…A cursor is a data structure that contains multiple rows of data, and it allows…us to cycle through each row one at a time and perform an action on each row.…Returning a cursor from a stored procedure is pretty similar to returning data…from a stored procedure using output parameters.…And in a lot of ways you can think of a cursor as a special type of output parameter.…I have some code on the screen.…This code is available in your exercise files.…
The top-half of this code is going to create a stored procedure called procedure…cursor that accepts one parameter that's called Authors, and that parameter has…a data type that is defined by two words;…one word is CURSOR and the second word is VARYING.…Meaning, this cursor isn't always going to be exactly the same.…It could be a different size based on the data that's currently in the database.…This cursor will sometimes return a different number of records than other times.…
