Par2: Trigger to convert MS SQL date to Clarion date
2004-06-11 -- Leslie Dean
 
I'm not sure if this is what you want, but I have a stored procedure that I ship with FM3... CREATE procedure ds_ConvertClarionDateTime @ClaDate int = 0, @ClaTime int = 0, @SqlDateTime datetime output as declare @SqlDate int -- date days declare @SqlTime decimal(38,12) -- time days declare @ClaRoot datetime declare @MssqlRoot datetime declare @OneMssqlSecond decimal(38,12) set @OneMssqlSecond = 0.000011574077 -- 1 mssql second in days set @ClaRoot = 'Dec 28, 1800' -- Root date for Clarion Date set @MSSQLRoot = 'Jan 01, 1900' -- Root date for MSSQL Date set @SqlDate = @ClaDate - datediff(day,@ClaRoot,@MssqlRoot) -- clarion date - the difference between root dates set @SqlTime = (@ClaTime / 100) * @OneMssqlSecond -- clarion time / 100 * day value of mssql seconds if @ClaDate > 2994626 -- invalid Clarion Date return 1 if @ClaTime > 8640000 -- invalid Clarion Time return 2 if @ClaDate = 0 begin if @ClaTime = 0 return -1 -- zero date and time else set @SqlDateTime = convert(datetime,@SqlTime,0) -- convert to datetime type with only time - date = root end else begin if @ClaTime = 0 set @SqlDateTime = convert(datetime,@SqlDate,0) -- convert to datetime type with only date - time = root else begin set @SqlDateTime = @SqlDate + @SqlTime -- add date + time set @SqlDateTime = convert(datetime,@SqlDateTime,0) -- convert to datetime end end GO
