How to set other values when the Oracle field is empty?

You can use Oracle’s COALESCE function to set a field to another value when it is empty. The COALESCE function accepts multiple parameters and returns the first non-empty parameter in order. If the first parameter is empty, it will return the second parameter, and so on.

For instance, if you have a field named “column1” and you want to replace it with “other_value” if it is empty, you can use the following query:

SELECT COALESCE(column1, 'other_value') AS new_column
FROM your_table;

This will return a new column called “new_column” with a value of “other_value” if “column1” is empty, or the value of “column1” otherwise.

You can also use other columns or expressions as replacement values in the COALESCE function. For example, if you have two fields “column1” and “column2”, and you want to replace the empty values in “column1” with the values in “column2”.

SELECT COALESCE(column1, column2) AS new_column
FROM your_table;

This will create a new column called “new_column”, where the value will be the value of “column2” if “column1” is empty, otherwise it will be the value of “column1”.

I hope this is helpful to you!
