To handle null timestamps using COALESCE in Teradata, you can use the following syntax:
1 2 |
SELECT COALESCE(timestamp_column, current_timestamp) AS new_timestamp FROM your_table; |
In this syntax, timestamp_column
is the column in your table that may contain null timestamps. COALESCE
is a function that returns the first non-null value in the list of arguments. In this case, if timestamp_column
is null, it will be replaced with the current timestamp.
This will ensure that you do not have null values in your timestamp column and instead have them replaced with the current timestamp.
