Timestamp issues about inserting a large number of records at once

Riley 380 Reputation points

Here is what I am concerned:

If I have a transaction inserts 1 million records using the getdate() function, will there be different timestamp, or will the inserted create_time always be the same?

insert into table1(id,create_time)  select id,getdate() from table2

Thanks in advance!

    Hi @Siver

    As far as I know, Getdate() returns the same value in one single statement.

    If you want to ensure the same inserted create_time, it is recommended to assign getdate to a parameter and then use this parameter in the insert statement.
