Re: [sqlite] HELP: SQLException getErrorCode vs gerErrorMessage()
I've only used the xerial driver recently and haven't checked for the error code on exception. It does come with source, so you may be able to walk into the code to see how the value is set/retrieved. ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
Re: [sqlite] HELP: SQLException getErrorCode vs gerErrorMessage()
Any one with java/JDBC experience please have a look at the snippet and
let me know why I am not able to get the exact errorCode.
Thanks

Re: [sqlite] HELP: SQLException getErrorCode vs gerErrorMessage()
I am on windows 7 and this is my test code
try
{
Statement stat = mconn.createStatement();
stat.execute(sql);
resultSet = stat.getResultSet();
mconn.close();
break;
}
catch (SQLException e)
{
retryCount++;
switch(e.getErrorCode())
{
case SQLITE_BUSY :
/* falls through */
case SQLITE_LOCKED :
/* falls through */
case SQLITE_PROTOCOL :
if ( mlogger != null )
{
mlogger.logWarn(0, "getResultSet() ",
String.format("%s, Error code : %d", e.getMessage(),e.getErrorCode()));
}
/*
* swallow the exception and retry once again
*/
break;
default :
if ( mlogger != null )
{
mlogger.logError(0,"getResultSet()
",String.format("Insert query returned error: %s Error code : %d",
e.getMessage(), e.getErrorCode()));
}
/*
* The old driver was throwing SQLException with
message "database locked" or "database is locked" with
* error code 0. Even though we moved to new driver, we
may need to have a fall back for a while.
*/
if (!("database
locked".equalsIgnoreCase(e.getMessage()) || "database is
locked".equalsIgnoreCase(e.getMessage(
{
return null;
}
/*
* swallow the exception and retry once again
*/
}
}
This is my connection code
try {
Class.forName("org.sqlite.JDBC");
mconn = DriverManager.getConnection("jdbc:sqlite:"+
connectionString);
} catch (SQLException e) {
if ( mlogger != null ) mlogger.logError(0, "openConnection() ",
e.getMessage());
e.printStackTrace();
return false;
} catch (Exception e) {
if ( mlogger != null ) mlogger.logError(0, "openConnection() ",
e.getMessage());
e.printStackTrace();
}
I tried this test using the driver from xerial and also from sqlite.
Both of them are returning the wrong error codes. Let me know if any
further information helps.
Thanks

Re: [sqlite] HELP: SQLException getErrorCode vs gerErrorMessage()
Hello Sridhar, please tell us more: what interface are you using? what OS? SQLException is not a part of the sqlite library, so obviously you use an additional layer.
