Hi. My question as said in the title is how to insert only one value into a single column of a table. INSERT statement doesn't seem to suffice since it always does its insertion row by row and fills the rest of the columns with null values.
Thanks in advance.

(P.S. i know dynamic SQL so your answer can include it if you want.)

You cannot insert a single column, only a full row.
If all your columns int the table allow null, you can use a query like this

SQL

INSERT INTO table_name (single_column) VALUES (some_value);

Otherwise you can only update an existing row and this can be done for a single column.

SQL

UPDATE table_name SET single_column = some_value WHERE primary_key = a_value;

(Or a natural key)

Maybe do some reading on your own.
