Question

I am not sure that writing SP with two update statements correct.

I am getting Incorrect syntax near ‘@ItemID’.
Can you suggestion me … How can i resolve this.

CREATE PROCEDURE [dbo].[ComponentReplaceUSP](@ReplaceItem nvarchar(256) ,@Quantity decimal(28,12) ,@UOM nvarchar(30)) 

AS  
 DECLARE @ItemID INT    
BEGIN       

   Select @ItemID = ItemID  FROM [dbo].[Item] WHERE ItemName =  @ReplaceItem

    UPDATE Item    
      SET Item.ItemName = @ReplaceItem,
      Item.UOM = @UOM
      Where Item.ItemID =@ItemID    


      Update ItemBillOfMaterial
      Set ItemBillOfMaterial.UOM =@UOM,
          ItemBillOfMaterial.Quantity =@Quantity
          Where  ItemBillOfMaterial.CompItem= @ItemID   

Answer 1

Your CREATE PROCEDURE query requires an END:

CREATE PROCEDURE [dbo].[ComponentReplaceUSP](@ReplaceItem nvarchar(256) ,@Quantity decimal(28,12) ,@UOM nvarchar(30)) 
AS   
DECLARE @ItemID INT  
BEGIN           
   Select @ItemID = ItemID  FROM [dbo].[Item] WHERE ItemName =  @ReplaceItem
END
