How to view linq to sql generated sql statements?


Asked by Augustine Chase on Dec 07, 2021 SQL



For debugging purposes, it is necessary to view generated SQL statements. There are several ways we can do this. One of the easiest ways is to write the generated SQL queries to ASP.NET page or a console Window. Thus, let’s flip to Visual Studio, which we will be using.
Also Know,
You will get the generated SQL query in console as follows: You can set or get log of the DataContext in a TextWriter. If required you can save them on a file system etc. Happy Coding. It is very common that may come in your mind that, how we can see SQL query being generated at the back end for LINQ query.
Indeed, Here is an example, where we will create a console Application. Add a LINQ to SQL class file. Drag and drop the respective table. Now, copy this code in the main method.
Thereof,
Now, this LINQ query is not compiled, which means every time this LINQ query is executed, this must be passed and then T-SQL statements must be dynamically generated on the fly and this parsing takes time. Thus, this parsing overhead can be removed by compiling this LINQ query.
Besides,
In most of the cases, LINQ to SQL does a pretty decent job in generating optimal SQL queries. When we use ExecuteQuery () or ExecuteCommand () methods, we lose the expressive power of LINQ and the advantage of having strongly-typed variables in the queries. What is the difference between ExecuteQuery and ExecuteCommand methods in LINQ?
