// 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.
