Can I use… smallint (column type)

1. Accepts character strings (generously cast or not statically typed)
2. Use int64

The SQL type smallint is typically no shorter than a 16 big signed integer (-32768 to 32767).

CREATE TABLE table_name (
   column_name SMALLINT
)

Note that the SQL language has no unsigned modifier (see: domain, check).

• Smallint in other places: cast target.

• Other integer types: integer/int, bigint

• Restricting the value range (e.g. unsigned): domain, check

• SQL types for decimal numbers: numeric, decimal, decfloat

• Numeric types with approximate arithmetic: float, real, double precision

• Product specific integer types: tinyint, mediumint, int2, int4, int8, int64, unsigned, signed

The type smallint is defined in ISO/IEC 9075:2016-2 (E011-01, “INTEGER and SMALLINT data types (including all spellings)”) with an implementation defined precision.0 The corresponding data type of the C programming language is short,1 which corresponds to the above mentioned value range.2
