Hi all.
It is difficult to debug user functions with SQLiteJDBC. For example I
have got a NullPointerException, but I don't know, why.
So… it is easy if you want to handle it. Just add to the Function.java:
private static Throwable lastException;
public static Throwable getLastException() {
Throwable e = lastException;
lastException = null;
return e;
}
final protected void internalxFunc() throws SQLException {
try {
xFunc();
} catch (Throwable e) {
lastException = e;
throw new SQLException(e.getMessage());
}
}
And call internalxFunc() instead of xFunc() in the Nested/Native driver.
Add in DB.java (on line 274)
case SQLITE_LOCKED:
throw new SQLException("database locked");
case SQLITE_MISUSE:
throw new SQLException(errmsg());
default:
finalize(stmt);
* * SQLException exception = new SQLException(errmsg());*
exception.initCause(Function.getLastException());
* throw exception;*
*
And similar with xStep() and xFinal().
Thank you for SQLiteJDBC and thank you for reading my email.
Just one thing: in JDBC world value_<type>() it not familiar. Why don't
use *get<type>()*? And *setResult(…)* instead of result(…)?
Thank you again,
Máté.
