need a sql expert

. Identify the differences in the population size estimates for each U.S. state the Census Bureau provided in two consecutive years using the most current data and the latest historical data datasets for the national total population in two different SQL tables.

J. Write a code to join the two tables on the year and state fields into one SQL table that identifies the absolute differences (in whole rounded hundreds) in the estimates of 10,000 individuals or more between the two datasets. If the earlier estimates are larger than 10,000, the cells should indicate a negative value. Provide a screenshot of your tested code showing successful execution.

K. Explain how you prepared the data and how the datasets were imported into two SQL tables. Provide a screenshot of the successfully executed SQL code.

L. Export the data from the SQL table into a CSV file, with rows representing the states and columns representing the years that both datasets estimate, that only shows the differences between the datasets (in whole rounded tens of thousands) that exceed 10,000 individuals.
