How to Use DbContext.Database.SqlQuery with Stored Procedures in Entity Framework Core?

Use DbContext.Database.SqlQuery in Entity Framework Code First to execute stored procedures

Using DbContext.Database.SqlQuery to call a stored procedure with parameters requires building a query string and providing parameters in the form of a SqlParameter object.

Build query string

Replace the stored procedure name with the actual procedure name and add parameter placeholders to the query string:

<code>"mySpName @param1, @param2, @param3"</code>

Create SqlParameter object

Create a SqlParameter instance for each parameter, providing its name and value:

<code>new SqlParameter("param1", param1)
new SqlParameter("param2", param2)
new SqlParameter("param3", param3)</code>

Execute query

Finally, execute the query using the constructed query string and SqlParameter object:

<code>context.Database.SqlQuery<myentitytype>(
    "mySpName @param1, @param2, @param3",
    new SqlParameter("param1", param1),
    new SqlParameter("param2", param2),
    new SqlParameter("param3", param3)
);</code>
