How to create web Api execute stored procedure - asp.net-mvc-4

Question

I work on SQL server 2012 and web API entity framework .NET core 2.2
so I face issue I can't implement web API execute stored Procedure below
Create proc ItemCalculateStock
#ItemId int = NULL,
#InventoryLocation int=NULL
as
begin
SELECT i.itemName,l.InventoryName, SUM(case when QTY > 0 then QTY else 0 end) as PurchasedItem,SUM(case when QTY < 0 then -QTY else 0 end) as ConsumItems,SUM(case when QTY > 0 then QTY else 0 end) + SUM(case when QTY < 0 then QTY else 0 end) as remaining
FROM [dbo].[Invenroty] n with(nolock)
inner join [dbo].[InventoryLocations] l with(nolock) on l.id=n.InventoryLocID
inner join [dbo].[Items] i with(nolock) on n.itemid=i.id
inner join [dbo].[TransactionTypes] t with(nolock) on n.transactionTypeId=t.ID and InventoryLocID=case when #InventoryLocation is null then n.InventoryLocID else #InventoryLocation end
and i.id=case when #ItemId is null then n.itemid else #ItemId end
GROUP BY i.itemName,l.InventoryName
end
so How to get result of stored procedure on web API using Entity Framework .NET core 2.2
[HttpGet("CalculateInventoryData")]
public IActionResult CalculateInventoryData([FromQuery]int optionId, [FromQuery] int ItemId, [FromQuery] int InventoryLocation)
{
// here how to get stored procedure result here
// so i ask question to know how to get result of stored procedure above
}
to call API I use the link below :
https://localhost:44374/api/Inventory/getInventoryData?optionId=1&ItemId=2&InventoryLocation=1
updated Post
I try below
context.Database.ExecuteSqlCommand("ItemCalculateStock #OptionId ,#ItemId,#InventoryLocation ", parameters: new[] {optionId,ItemId,InventoryLocation});
i get error cannot implicitly convert type int into to Microsoft .aspnetcore.mvc.action result
so how to solve issue

Answer 1

The code to execute a stored procedure without parameters is as follows:
SqlConnection conn=new SqlConnection(“connectionString”);
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = new SqlCommand();
da.SelectCommand.Connection = conn;
da.SelectCommand.CommandText = "NameOfProcedure";
da.SelectCommand.CommandType = CommandType.StoredProcedure;
The code to execute a stored procedure with parameters is as follows (we can declare the function that calls the stored procedure as ExeProcedure(string inputdate)):
param = new SqlParameter("#ParameterName", SqlDbType.DateTime);
param.Direction = ParameterDirection.Input;
param.Value = Convert.ToDateTime(inputdate);
da.SelectCommand.Parameters.Add(param);
This adds an input parameter. If you need to add output parameters:
param = new SqlParameter("#ParameterName", SqlDbType.DateTime);
param.Direction = ParameterDirection.Output;
param.Value = Convert.ToDateTime(inputdate);
da.SelectCommand.Parameters.Add(param);
To get the return value of the stored procedure:
param = new SqlParameter("#ParameterName", SqlDbType.DateTime);
param.Direction = ParameterDirection.ReturnValue;
param.Value = Convert.ToDateTime(inputdate);
da.SelectCommand.Parameters.Add(param);
