Write a SQL Query that uses the annual growth to get a projection for total population for the years 2022-2023 for each county. The calculation to be used is: current year total population * (1+annual growth). The annual growth is a percentage. For example the calculation using these two tables would be: 100,000*(1+.005) = result for 2022 population population projection result for 2022 population projection *(1+.006) = result for 2023 population projection CountyName A B C CountyName A B C I need a table that outputs: CountyName Year 2021 2022 2023 A A B B C C Year 2021 2021 2021 Year 2023 2022 2023 2022 2023 Annual Growth .005 .006 .003 Cumulative Growth .005 .011 .014 Total Population 100,000 200,000 300,000 Population Projection Result from calculation Result from calculation Result from calculation Result from calculation Result from calculation Result from calculation

Problem Your task is to write an SQL query that uses SQL's time constants to dynamically determine the timezone the database server is configured to use. Your query should return the timezone as a single string value with the timezone offset relative to the Coordinated Universal Time (UTC). The single output column should be named tz_offset, and the value should be in the form: UTC: where and use two digits in 24-hour format, padded with leading zeroes if necessary. Example: if the server used India's timezone the output should be: | tz_offset | | UTC+05:30 (1 row) query.sql> init.sql 1
