  1. Not as cast target: cast(… as <target>). Use cast(… as signed)
  2. Accepts character strings (not statically typed or generously cast)

Normative References

ISO/IEC 9075:2016-2 does not define a precision for these data types.0 The bit numbers above correspond to the data type mappings for the C programming language.1

The data types smallint, integer and int where already required for Entry SQL-92.
