hive sql cast

H SQL provides the CAST operator to convert data from one type to another. You can use it in your queries to ensure proper type conversions. Here's an example:

SELECT(column_name AS data_type) FROM table_name;

In the above query replace `column_name` the name of the column you to cast, and `_type` with the desired target data type. For instance, if you want to cast a column named `age` to an integer type, the query would be:

SELECT CAST(age AS INT) FROM table_name;

Hive supports various data such as INT, STRING, BOOLEAN, FLOAT, DOUBLE, etc. Make sure to choose the appropriate data type for your casting operation.
