Most of {es} <<mapping-types, data types>> are available in {es-sql}, as indicated below: Most of {es} <<mapping-types, data types>> are available in {es-sql}, as indicated below.
As one can see, all of {es} <<mapping-types, data types>> are mapped to the data type with the same
name in {es-sql}, with the exception of **date** data type which is mapped to **datetime** in {es-sql}:
