// The signature of the stored procedure SQLCAMessage I have come out so far is as follows:
// SQLCAMessage (
// IN SQLCode INTEGER,
// IN SQLErrml SMALLINT,
// IN SQLErrmc VARCHAR(70),
// IN SQLErrp CHAR(8),
// IN SQLErrd0 INTEGER,
// IN SQLErrd1 INTEGER,
// IN SQLErrd2 INTEGER,
// IN SQLErrd3 INTEGER,
// IN SQLErrd4 INTEGER,
// IN SQLErrd5 INTEGER,
// IN SQLWarn CHAR(11),
// IN SQLState CHAR(5),
// IN Locale CHAR(5),
// IN BufferSize SMALLINT,
// IN LineWidth SMALLINT,
// OUT Message VARCHAR(2400))
//
// Some issues have been identified:
// 1. What would be the schema name of the stored procedue SQLCAMessage?
// 2. What is the format and type of the Locale parameter? If there does, I would really like to know the format of the locale in order to decide the type of the Locale parameter. Even there does not either, the Locale parameter probably still needs to be kept there for future extension, and we need to figure out the format of the locale.
// 3. What would be the format of the output message? Is this full message text ok or do we only need the explanation message corresponding to an SQL code. This somehow matters whether we need the Buffersize and Linewidth parameters for the stored procedure.
// 4. What if the invocation of stored procedure failed (due to, eg, connection dropping)? In this case, we probably need to return some client-side message.
//
// Note that this class does NOT extend java.sql.SQLException. This is because
// in JDBC 4 there will be multiple subclasses of SQLException defined by the
// spec. So we can't also extend SQLException without having to create our
// own mirror hierarchy of subclasses.
//
// When Derby is ready to throw an exception to the application, it catches
// SqlException and converts it to a java.sql.SQLException by calling the
// method getSQLException.
//
// It is also possible that internal routines may call public methods.
// In these cases, it will need to wrap a java.sql.SQLException inside
// a Derby SqlException so that the internal method does not have to throw
// java.sql.SQLException. Otherwise the chain of dependencies would quickly
// force the majority of internal methods to throw java.sql.SQLException.
// You can wrap a java.sql.SQLException inside a SqlException by using
// the constructor <code>new SqlException(java.sql.SQLException wrapMe)</code)
