In SQL, to indicate that a column’s value is not empty (not null), you can use the IS NOT NULL condition. This condition is used to filter out records where a specific column is not NULL.

Here is a simple example:

SELECT * FROM table_name WHERE column_name IS NOT NULL;

In the example above:

  1. table_name is the name of the table.
  2. The column_name is the name of the column that needs to be checked for being not empty.

This query will return all the records in the table_name table where the value in the column_name column is not empty (non-NULL).
