@Company2 varchar(10),

@Accountfrom varchar(60),

@Accountto varchar(60),

@Datefrom datetime,

@Dateto datetime,

as

declare @char39 char for single quote mark

declare @SDatefrom as varchar(50)

declare @SDateto as varchar(50)

select @SDatefrom = cast(@Datefrom as varchar(50))

select @SDateto = cast(@Dateto as varchar(50))

select @char39=char(39)

if not exists (select * from dbo.sysobjects where id = object_id(Nก[dbo].[AST_INTEREST_TABLE]ก) and OBJECTPROPERTY(id, NกIsUserTableก) = 1)

CREATE TABLE [dbo].[AST_INTEREST_TABLE] (

[YEAR] [int] NULL ,

[YEARDEGBALANCE] [numeric](19, 5) NULL ,

[BEGBALANCE] [numeric](38, 5) NULL ,

[ENDBALANCE] [numeric](38, 5) NULL ,

[INTERESTONBALANCE] [numeric](38, 6) NULL ,

[INTERESONTRANSACTIONS] [numeric](38, 8) NULL ,

[INTEREST] [numeric](38, 6) NULL

) ON [PRIMARY]
