Question

I see the example of using Dapper in executing stored procedures with dynamic parameters, and returning the results of the procedure. Usually, the examples use .Execute, but a few of them use .Query. I have difficulty in using .Execute. Which am I supposed to use in the case described above–query or execute AND in what cases would I use each?

Answer 1

If you need to return a value, then use Query(). If you need to execute a query that does not return anything, an update for example, then use Execute().

Query example:

var myList = connection.Query("select * from myTable")

Execute example:

connection.Execute("update myTable set columnA = @value", new {value = "ABC"})
