Insert and Update in SQL Using User-Defined Table Type

Question

Following is new data type that I created.

CREATE TYPE [dbo].[UpdateHotelTableType] AS TABLE(
    [ID] [int] NULL,
    [HotelID] [int] NULL,
    [FromDate] [date         


        

Answer 1

You can Simply do 2 Queries: 1. "Update" command 2. "Insert" command.

ALTER PROCEDURE [dbo].[SP_Hotel_Info_Update]
     -- Add the parameters for the stored procedure here
    @XHotelInfoDetails UpdateHotelTableType READONLY,

AS
BEGIN

    UPDATE dbo.HotelInfo
    SET FromDate = r.FromDate,
    FROM dbo.HotelInfo 
    JOIN @XHotelInfoDetails X ON X.Id = HotelInfo.Id

    INSERT INTO dbo.HotelInfo (Col1,Col2)
    SELECT X.Col1,
           X.Col2
    FROM @XHotelInfoDetails X
    WHERE NOT EXISTS
                   (
                     SELECT 1
                     FROM dbo.HotelInfo InnerTable
                     WHERE X.Id = InnerTable.Id
                   )

END

Answer 2

Use MERGE:

Performs insert, update, or delete operations on a target table based on the results of a join with a source table. For example, you can synchronize two tables by inserting, updating, or deleting rows in one table based on differences found in the other table.

ALTER PROCEDURE [dbo].[SP_Hotel_Info_Update]
     -- Add the parameters for the stored procedure here
    @XHotelInfoDetails UpdateHotelTableType READONLY,

AS
BEGIN

    MERGE dbo.HotelInfo AS trg
    USING @XHotelInfoDetails AS src
      ON src.ID = trg.ID
     WHEN MATCHED THEN
       UPDATE SET FromDate = src.FromDate
     WHEN NOT MATCHED BY TARGET THEN
       INSERT (col1, col2, ...)
       VALUES (src.col1, src.col2, ...);
END

EDIT:

In my datatable, there can be newly added rows as well as deleted rows. So how can I compare the id and delete rows from hotelinfo table?

You could add new clause:

WHEN NOT MATCHED BY SOURCE [ AND <clause_search_condition> ]  
     THEN DELETE;

with specific condition to delete data from target.
