### Typed Literals in ABAP SQL
Typed literal:
- Literal whose data types is defined by specifying a [built-in dictionary type](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenddic_builtin_types.htm) explicitly.
- Available for most but not all ABAP Dictionary data types.
- Can be used in ABAP SQL and in ABAP CDS.
- More information: Typed literals in [ABAP SQL](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenabap_sql_typed_literals.htm) ([cast expressions in ABAP SQL](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abensql_cast.htm)) and [ABAP CDS](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abencds_typed_literal_v2.htm)
