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 tried to attach database in Android Room like this: How to select from multiple databases in Android Room(How to attach databases) but i got error when building project:
error: There is a problem with the query: [SQLITE_ERROR] SQL error or missing database (no such table: database.table)
Error concerns
#Query("select t.id as tid from mydatabase.mytable t")
public List<MyPojo> getMyTableIds();
When I added #SkipQueryVerification, error changed on: error: Not sure how to convert a Cursor to this method's return type.
Error dissapears when I remove "mydatabase." from Query.
How to attach database in Android Room and make cross databases query?
You can attach your another database in onOpen callback. For details see the answer of another post here.
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'm getting a weird error in DDMS, it appears just after the innocent "Finalizing a Cursor that has not been deactivated or closed", comming from my own DataAdapter (about that in next question)
Error:
"Finalizing a Cursor that has not been deactivated or closed. database = /data/data/net.toload.main/databases/lime, table = null, query = SELECT _id, code, code3r, word, score FROM mapping WHERE code3r = '0' AND code ='HTT' ORDER BY cod"
I didn't create any tables with such columns in my app! And my localdatabase isn't stored there... /databases/lime, but this error seems to come just after my real error from my own DataAdapter. I tried to pull the lime.db file to read the contents of the database but the pulled file is always of 0 bytes, though on DDMS-FileExplorer is much more, now 26624bytes.
So ... im thinking that maybe android/google is tracking my every move!! and the app doesnt run in a isolated process...
Anyway can you explain this error?
Your project must be using this Lime IME (Lightweight Input Method Editor):
http://code.google.com/p/limeime/
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?

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.
