问题描述

我有带有时间戳格式的表列的SQL Server数据源。

I have SQL Server data source with table column with timestamp format.

我有Azure SQL DW目标,它不支持时间戳。所以用bigint创建了列。

推荐答案

根据此链接。

https://docs.microsoft.com/en-us/sql/t-sql/data-types/rowversion-transact-sql?view=sql-server-2017

A nonnullable  rowversion   column
在语义上等同于 
binary(8)  列。
可以为空的
rowversion  列
在语义上等同于 
varbinary(8)   column。

A nonnullable rowversion column is semantically equivalent to a binary(8) column. A nullable rowversion column is semantically equivalent to a varbinary(8) column.

这是我试过的,我把sink列类型作为二进制(8)和source(SQL Server)作为时间戳,它对我有效。 

This is what I tried , I had the sink column type as binary(8) and the source ( SQL Server ) as timestamp and it worked for me . 

接收器:

创建表Testtimesatamp_sink



id int identity(1,1),

name varchar(100),

timestampcolumn binary( 8)

$

create table Testtimesatamp_sink
(
id int identity(1,1) ,
name varchar(100) ,
timestampcolumn binary(8)

)

来源: 

我还尝试使用&time:timestampcolumn  varbinary(8)它工作得很好。 

I also tried with timestampcolumn  varbinary(8) and it just worked fine . 

请告诉我它是怎么回事。

Please do let me know how it goes .
