Sybase IQ supports the SQLSTATE error code defined by SQL/92.
Each SQL State (SQLSTATE) value is a 5-character string containing a 2-character class followed by a 3-character subclass. Each character can be one of the uppercase letters A through Z or the digits 0 through 9. A class that begins with A through H or 0 through 4 has been defined by the ANSI standard; other classes are implementation defined. Similarly, subclasses of standard classes that start with the same characters (A-H, 0-4) are standard. The subclass 000 always means that no subclass code is defined. The most common SQLSTATE value is 00000, which indicates successful completion.
Implementation-defined classes and subclasses start with 'Q'.
