bookChallenge: Creating B-tree Index

Task

We have considered in the previous chapter that the B-tree index can be created using the following syntax:

Now let's continue working with the BankAccounts table as in the previous chapter. Given that we frequently work with balance ranges when dealing with bank accounts, it would be beneficial to create a B-tree index on the balance column.

Your task is to create a new B-tree index on the balance column of the BankAccounts table. Please ensure that you directly specify a B-tree index and do not rely on the default index:

  • specify balance_index as the name of the index.
  • the index is created for BankAccounts table.
  • the index is created using balance column.
