Im getting this error:
10-05 19:36:09.904: WARN/System.err(1039): android.database.sqlite.SQLiteConstraintException: error code 19: constraint failed
Is there a way to the class SQLiteDatabase show queries created in insert and update methods?
Ty
You are probably inserting two items with the same primary key, which is supposed to be unique. There is no way that I know of to get verbose SQL logs, sorry.

I use insertOrThrow in my android code to insert rows in to sqlite database. I use try catch to trap SQLiteException. I have set unique constraint in a column other than _id.
In case of errors i get exception message like the following and that is what i wanted.
"column word is not unique (code 19)"
Now, if the error is about duplicate insertion then i get the above error. And i would get messages like that for different errors.
What i need is an error number like in mysql. I was searching for a property of the android DB object which would have an error code but could not. I think in this case i need to parse the error message to get the error code.
The reason to have an error code is to identify the errors. In this case i can find duplicates if the error code is 19. If the entry is a duplicate then i will display 'Data already exists' message else i will display a generic error info like 'Unable to save information'.
Is there any other way to find the error code other than parsing?
Will the error code be consistent?
I downloaded the demo code.
After running the code :
I am getting this screen. I signed in with same username and id on other device, but nothing is happening.
On entering text, I'm getting the following error :

Please help if anyone knows about it!
The demo app relies on the soft keyboard to add new items, so make sure to have it enabled in your emulator or device.
I'll research the sql error, but it appears to only show in the emulator log and not on a real device.
The error states:
UNIQUE constraint failed: changeVersions.bucketName
bucketName has a UNIQUE constraint, which means that each new inserted value has to be unique.
So you tried to insert an object with a bucketName which already existed in the database.
If you think you can have multiple objects with the same bucketName, remove the constraint.
If you shouldn't, check before inserting if there's already one, and handle it gracefully.
How do I get the name of the constraint which caused the SQLiteConstraintException.
Calling toString() on the exception just gives me: "error code 19: constraint failed"
And there is no method in the exception to get the cause. This makes it rather difficult to debug my sql.
Beginning with version 3.7.17, SQLite shows the name of the constraint in error messages:
sqlite> create table t(x, constraint x_positive check (x>0));
sqlite> insert into t values(-1);
Error: constraint x_positive failed
However, it will be some time before this version shows up in Android.
In the meantime, you could replace the constraint with a trigger that can use whatever message it likes:
CREATE TRIGGER check_x_positive
BEFORE INSERT ON t -- also UPDATE
FOR EACH ROW
WHEN NEW.x <= 0
BEGIN
SELECT RAISE(ABORT, 'RED ALERT! database on fire because x <= 0');
END;
One of my tables in my SQLite database is returning this error code below:
sqlite returned: error code = 17, msg = prepared statement aborts at
32[sql statement]
As far as I know, the data was successfully inserted. Is this something I should be concerned about? Or is it just a false error? Based on this post, it says:
The database schema changed
What exactly does it mean? Any suggestions?
Try insetting more elements it seems false error, once you inserted values your database schema recognized and stops giving this false error..
I'm getting the same error. Are you dropping your database and then re-populating it? This "warning" appears when I wipe out my database and then insert about 200 rows again ... but all works fine. It's strange. There is a thread in the sqlite forum about this.
I have a common problem, and have looked at several solutions but haven't seen one that fits this case.
I have a temporary table that is defined as follows:
public static final String GROUP_TABLE_CREATE =
"CREATE TEMP TABLE "+GROUP_TABLE_NAME+" ("
+GROUP_ID_COLUMN_NAME+" INTEGER PRIMARY KEY AUTOINCREMENT, "
+GROUP_GROUP_ID_COLUMN_NAME+" INTEGER NOT NULL UNIQUE, "
+GROUP_COLUMN_NAME+" VARCHAR(64) NOT NULL)";
The table is created without any problems. I then download some data to insert into it and use the following query to insert it:
ContentValues contentValues = new ContentValues();
contentValues.put(WhereWolfOpenHelper.GROUP_GROUP_ID_COLUMN_NAME, groupID);
contentValues.put(WhereWolfOpenHelper.GROUP_COLUMN_NAME, groupName);
db.insert(WhereWolfOpenHelper.GROUP_TABLE_NAME, null, contentValues);
And then I get the following error:
08-05 08:52:37.791: ERROR/Database(847): Error inserting group_name=Friends group_id=2
08-05 08:52:37.791: ERROR/Database(847): android.database.sqlite.SQLiteConstraintException: error code 19: constraint failed
The error appears twice, and the only data in the database is the group named Friends (there should be two more entries).
I have another table with very similar code that works without any problems, so I'm guessing it's just some silly mistake that I haven't spotted. Anyone got any ideas?
If "constraint failed" than something in table scheme should tell us what is wrong.
I see what it show data what it want to insert, this means what NOT NULL constraint is OK.
In this case I've only one assumption what you already inserted some GROUP_GROUP_ID_COLUMN_NAME with value 2 and UNIQUE constraint is failed because of that.
Are you using a temporary table on purpose? A temporary table dies once the DB connection is closed. If this is the case, the table will get created and the insert will not correspond to any table. So the constraint 19 can correspond to 'Table not found'
You shouldn't pass null values in insert method. Pass empty strings.
