如何将 DB2 时间戳转换为 SQL Server datetime2？

Question

I am converting DB2 stored procedures to SQL Server. One of the common issue is that DB2 use a time date format timestamp very commonly, for which the closest SQL Server equivalent appears to be datetime2 .

What is an easy way to convert DB2 timestamp to datetime2 ?

I found this question but there was not any answer.

Answer 1

DB2 timestamp is very similar to SQL Server datetime2 , except a hyphen and using periods instead of colons.

You can use stuff() to change those characters and then convert() to datetime2 .

Examples:

declare @DB2_timpstamp varchar(30)
declare @SQL_datetime2 datetime2
set @DB2_timpstamp = '2019-02-02-11.22.33.456789'

set @SQL_datetime2 = try_convert(datetime2, stuff(stuff(stuff(@DB2_timpstamp, 17, 1, ':'), 14, 1, ':'), 11, 1, ' '))
select @SQL_datetime2
