SQL Query to Retrieve Specific URL Value

To write an SQL query that returns the value 'http://localhost/blah/' from a specific field, you would need to know the table name and column name where this value is stored. Assuming the table is named 'example_table' and the column is named 'url_field', you can use the following query:

SELECT url_field
FROM example_table

This query will return all the values stored in the 'url_field' column of the 'example_table' table. If you specifically want to retrieve the value 'http://localhost/blah/' from the field, you can add a WHERE clause to filter the results:

SELECT url_field
FROM example_table
WHERE url_field = 'http://localhost/blah/'

This query will only return rows where the 'url_field' column has a value of 'http://localhost/blah/'.
