Explain what is a Hive variable. What do we use it for?..

Answer / Sudil Kumar

A Hive variable is a placeholder that can hold a value during the execution of a query. It allows for dynamic SQL queries by allowing you to store and reuse values inside the query. Variables are declared using the SET command.nnExample: SET var_name = 'value'; SELECT var_name as var, column_name FROM table;
