How to Use DbContext.Database.SqlQuery with Stored Procedure Parameters?

Use the DbContext.Database.SqlQuery(sql, params) method to call a stored procedure with parameters

Question:

When trying to use the DbContext.Database.SqlQuery<T>(sql, params) method to retrieve data from a stored procedure with parameters, an error occurs stating that the parameters are missing. How can I use this method to call a stored procedure with parameters?

Answer:

In order to efficiently use the DbContext.Database.SqlQuery<T>(sql, params) method to call a stored procedure that requires parameters, a SqlParameter instance should be provided as follows:

<code class="language-csharp">context.Database.SqlQuery<MyEntityType>(
    "mySpName @param1, @param2, @param3",
    new SqlParameter("param1", param1),
    new SqlParameter("param2", param2),
    new SqlParameter("param3", param3)
);</code>

With this approach, you can specify the required parameters to ensure that the stored procedure executes successfully and retrieves the expected results.
