TO_BYTE is an overloaded scalar function. It is defined with the following parameter data types:

  • BYTEINT
  • SMALLINT
  • INTEGER
  • BIGINT

All expressions passed to this function must either match these declared data types or can be converted to these types using the implicit data type conversion rules that apply to UDFs.

The UDF implicit type conversion rules are more restrictive than the implicit type conversion rules normally used by Vantage. If an argument cannot be converted to one of the declared data types by following UDF implicit conversion rules, it must be explicitly cast.

If the argument cannot be converted to one of the declared data types, an error is returned indicating that no function exists that matches the DML UDF expression submitted.
