COLUMN NAMES IN LOWERCASE
To get the column names in lowercase you can use ‘as column_name’ in the SQL statement.
Query: SELECT ID as "id", FIRST_NAME as "first_name", LAST_NAME as "last_name", PHONE_NUMBER as "phone_number" FROM contacts WHERE last_name = 'Kumar' Result: id first_name last_name phone_number 345 Anand Kumar 8967537252 123 Naveen Baby 7658908333 674 Arthi Ranjith 7856341209 124 Rani Selvi 9994456345 76 Chandra Ambi 9345678211
