Data Types
Impala supports a set of data types that you can use for table columns, expression values, and function arguments and return values.
Note:
Currently, Impala supports only scalar types, not composite or nested types. Accessing a table containing any
columns with unsupported types causes an error.
For the notation to write literals of each of these data types, see Literals.
See SQL Differences Between Impala and Hive for differences between Impala and Hive data types.
