Class and subclass codes
To determine the success of an SQL statement, your program
must be able to interpret the value in the SQLSTATE variable. SQLSTATE consists
of a two-character class code and a three-character subclass code.
In the following figure,
IX
is the class code and 000
is
the subclass code. The value "IX000"
indicates an
error specific to HCL
OneDB™. SQLSTATE can contain only digits and capital letters. The class code is unique but the subclass code is not. The meaning of the subclass code depends on the associated class code. The initial character of the class code indicates the source of the exception code, which the following table summarizes.
Initial class- Code value | Source of exception code | Notes® |
---|---|---|
0 - 4 A - H |
X/Open and ANSI/ISO | The associated subclass codes also begin in the range 0 - 4 or A - H. |
5 - 9 | Defined by the implementation | Subclass codes are also defined by the implementation. |
I - Z | Any of the error messages specific to HCL
OneDB (those
that the X/Open or ANSI/ISO reserved range does not support) have
an SQLSTATE value of "IX000". If a user-defined routine returns an error message was defined by the routine, the SQLSTATE value is "U0001". |
