security.HexBinary.ToStringWithCharset

Decodes an hexadecimal string to a clear, human-readable string, based on a given charset.

Syntax

security.HexBinary.ToStringWithCharset(
   hexVal STRING,
   charset STRING )
  RETURNS STRING
  1. hexVal defines the string in hexadecimal.
  2. charset defines the character set to be used.

Usage

Decodes the given hexadecimal string and returns it in its clear human readable form, based on a given charset.

The original hexadecimal encoded string is first decoded to a string that will then be converted from the specified charset to the local DVM charset. In case of charset conversion error, the error -15700 is raised.

If the hexadecimal string does not contain a human readable string, the method will raise an exception.

In case of error, the method throws an exception and sets the status variable. Depending on the error, a human-readable description of the problem is available in the sqlca.sqlerrm register. See Error handling in GWS calls (status).
