问题 I have a simple procedure in MySQL (same as in Retrieving values of function output/proc output parameters in JavaScript from ADODB commands to MySQL?). As an attempt to get around the dead end of not being able to fetch the values of the output parameters, I started working on this from the aspx.cs component of a C# VisualStudio website project. However, this method so far doesn't even execute the procedure, let alone return the values. //MySQL Procedure - where user readonly has read and

I've now started to transition over to stored procedures with parameters to better protect the database from SQL injection, as well as just using as close to best practice as I can. However, when I'm using Dapper's QueryAsync<T> (This also applies to Query<T> ) along with DynamicParameters , I get an

问题 I have a table full of products, previously we passed a MaxPrice and MinPrice to the stored procedure and selected products with the price between two values. But now I want to pass multiple range values and want to select products that their prices are between multiple ranges.
