If your Windows 11 taskbar is not showing, you can try several troubleshooting steps to resolve the issue. Here are some potential solutions you can try:
In Entity Framework Core, you can call a stored procedure using the FromSqlRaw
method of the DbSet
class. Here are the steps to call a stored procedure in Entity Framework Core:
- Define a model class that represents the result set of the stored procedure. The properties of the model class should match the column names of the stored procedure result set.
csharppublic class CustomerOrder
{
public int CustomerId { get; set; }
public string CustomerName { get; set; }
public int OrderId { get; set; }
public DateTime OrderDate { get; set; }
}
- Define a
DbContext
class that includes aDbSet
property for the model class.
csharppublic class MyDbContext : DbContext
{
public DbSet<CustomerOrder> CustomerOrders { get; set; }
// ...
}
- Call the stored procedure using the
FromSqlRaw
method of theDbSet
class.
csharpvar customerOrders = dbContext.CustomerOrders.FromSqlRaw("EXECUTE dbo.GetCustomerOrders").ToList();
Replace GetCustomerOrders
with the name of your stored procedure. This will execute the stored procedure and map the result set to a list of CustomerOrder
objects.
- You can also pass parameters to the stored procedure by including them in the SQL query.
csharpvar customerId = 123;
var customerOrders = dbContext.CustomerOrders.FromSqlRaw("EXECUTE dbo.GetCustomerOrders @CustomerId", customerId).ToList();
This will execute the stored procedure with the @CustomerId
parameter set to 123
.
That's it! You have now called a stored procedure in Entity Framework Core and mapped the result set to a list of model objects.
