在复制中经常会使用到16进制的LSN,但在日志fn_dblog中的LSN是数字形式，于是从网上找到以下转换函数
CREATE FUNCTION
dbo.fn_convertnumericlsntobinary(
@numericlsn numeric(25,0)
) returns
binary(10)
AS
BEGIN
-- Declare components to be one step larger than
the intended type
-- to avoid sign overflow problems. For example,
convert(smallint, convert(numeric(25,0),65535)) will fail but convert(binary(2),
-- convert(int,convert(numeric(25,0),65535))) will give the
-- intended
result of 0xffff.
declare @high4bytelsncomponent
bigint,
@mid4bytelsncomponent bigint,
@low2bytelsncomponent int
select
@high4bytelsncomponent = convert(bigint, floor(@numericlsn /
1000000000000000))
select @numericlsn = @numericlsn - convert(numeric(25,0),
@high4bytelsncomponent) * 1000000000000000
select @mid4bytelsncomponent =
convert(bigint,floor(@numericlsn / 100000))
select @numericlsn = @numericlsn
- convert(numeric(25,0), @mid4bytelsncomponent) * 100000
select
@low2bytelsncomponent = convert(int, @numericlsn)
return convert(binary(4),
@high4bytelsncomponent) +
convert(binary(4), @mid4bytelsncomponent)
+
convert(binary(2), @low2bytelsncomponent)
END
