Before jumping on the tools introduction. let us understand why the SQL code formatting is important?

Why do you want to format SQL code?

As explained earlier, the formatted SQL code will makes your life easy. For example, consider below code that is extracted from the database. This query is to get information on customer return details from TPCDS benchmark tables.

select sr_customer_sk as ctr_customer_sk ,sr_store_sk as ctr_store_sk ,sum(SR_REVERSED_CHARGE) as ctr_total_return from store_returns ,date_dim where sr_returned_date_sk = d_date_sk and d_year =1999 group by sr_customer_sk ,sr_store_sk limit 10;

As you can see from above example, SQL code is messy and hard to understand. Now let us format it.

select 
  sr_customer_sk as ctr_customer_sk, 
  sr_store_sk as ctr_store_sk, 
  sum(SR_REVERSED_CHARGE) as ctr_total_return 
from 
  store_returns, 
  date_dim 
where 
  sr_returned_date_sk = d_date_sk 
  and d_year = 1999 
group by 
  sr_customer_sk, 
  sr_store_sk 
limit 10;
