One common task when working with databases is checking for null values in queries. In PostgreSQL, you can easily check for null values using the **IS NULL** or **IS NOT NULL** operators.<\/p>\n

To check for null values in a PostgreSQL query, you can use the following syntax:
\n“`
\nSELECT * FROM table_name WHERE column_name IS NULL;
\n“`<\/p>\n

This query will return all rows where the value in the specified column is null.<\/p>\n

If you want to check for non-null values, you can use the **IS NOT NULL** operator:
\n“`
\nSELECT * FROM table_name WHERE column_name IS NOT NULL;
\n“`<\/p>\n

Using these operators, you can easily filter out null values from your query results and perform any necessary operations on the non-null data.<\/p>\n
