Question

I have a database table in mysql with a field that is of “TIMESTAMP” type. I need help writing the SQL query to update the field with the current timestamp.

UPDATE tb_Test set dt_modified = ?????

Answer 1

Use:

UPDATE tb_Test 
   SET dt_modified = CURRENT_TIMESTAMP
 WHERE ? -- if you don't specify, ALL dt_modified values will be updated

You can use NOW() instead of CURRENT_TIMESTAMP, but CURRENT_TIMESTAMP is ANSI standard so the query can be ported to other databases.
