To create a SQL query where a string field is empty, you can use the IS NULL
or =''
conditions. Here's an example query using both conditions:
SELECT * FROM your_table_name
WHERE your_string_field IS NULL
OR your_string_field = '';
This query will return all rows from your_table_name
where your_string_field
is either null or an empty string. Replace your_table_name
and your_string_field
with your actual table and column names.
