Final answer:
The SQL query selects code, inflation rate, and unemployment rate from the 'economies' table for 2015, excluding records with a specified government form from the 'countries' table.
Step-by-step explanation:
The SQL query to select the code, inflation rate, and unemployment rate from the 'economies' table for the year 2015, while excluding the codes from the 'countries' table where the government form is like 'gov_form LIKE', can be written as follows:
SELECT e.code, e.inflation_rate, e.unemployment_rate
FROM economies AS e
WHERE e.year = 2015
AND e.code NOT IN (
SELECT c.code
FROM countries AS c
WHERE c.gov_form LIKE '%
specific government form%
'
);
In this query, replace specific government form with the appropriate government form you wish to exclude. This query fetches the desired data from the economies table for a particular year and filters out records that match certain criteria in the countries table.
