Question

When using this statement

create table demo (
    ts timestamp
)

insert into demo select current_timestamp

I get the following error:

Cannot insert an explicit value into a timestamp column. Use INSERT with a column list to exclude the timestamp column, or insert a DEFAULT into the timestamp column

How do I insert the current time to a timestamp column?

Answer 1

According to MSDN, timestamp

Is a data type that exposes automatically generated, unique binary
numbers within a database. timestamp is generally used as a mechanism
for version-stamping table rows. The storage size is 8 bytes. The
timestamp data type is just an incrementing number and does not
preserve a date or a time. To record a date or time, use a datetime
data type.

You’re probably looking for the datetime data type instead.
