Insert error android.database.sqlite.sqliteconstraintexception code error 19 failed

Question

I know there are so many threads in this problem, but not one of my own problems. I have a counter connected in a database that displays the foreign key of a specific table. And an error insert appears.

Insert method encoded into my databaseconnector

  public void insertConsumption(String meter_number, String current, String previous, String kWh, String date, String consumer_name) { ContentValues newCons = new ContentValues(); newCons.put("_id", meter_number); newCons.put("Current", current); newCons.put("Previous", previous); newCons.put("kWh", kWh); newCons.put("Date", date); newCons.put("ConsumerName", consumer_name); open(); database.insert("Consumptions", null, newCons); close(); }

I am stuck in this problem. Please help me. Thanks for the future reply.

Answer 1

It looks like some of the values ​​you insert may be NULL for the NOT NULL fields (username in your case) or PK (_id in your case) already exists. Error code 19 means that during the operation the table restriction (NOT NULL, UNIQUE, etc.) (INSERT, etc.) was violated. The following is a list of SQLITE error codes

android.database.sqlite.SQLiteCursor@4144fa58 - The spam value assigned by ConsumerName. Therefore, please do some workaround to get the correct FK for ConsumerName from the cursor.

Something is wrong with you with SimpleCursorAdapter. So please look at that. If you get the correct values ​​in a spinner, then please get the selected value from spineer spinner.getSelectedItem spinner.getSelectedItem().toString(); instead of spinner.getItemAtPosition(mSpinnerSpeciesId).toString() .

Hope this helps you.

Answer 2

A constraint failure usually indicates that you did something like passing a null value to a column that you declare non-zero when creating your table.

So, Remove not null and put null when creating the table.

Answer 3

I got the same error and solved it by setting ID NULL to the code. Since the PK SqlLite identifier auto-increments its value, it does not need to be set.

 public void insertConsumption(String meter_number, String current, String previous, String kWh, String date, String consumer_name) { ContentValues newCons = new ContentValues(); //newCons.put("_id", meter_number); newCons.put("Current", current); newCons.put("Previous", previous); newCons.put("kWh", kWh); newCons.put("Date", date); newCons.put("ConsumerName", consumer_name); open(); database.insert("Consumptions", null, newCons); close(); } 

Answer 4

you specified the column "colAccountID" as PRIMARY KEY, so the SQLite db throw error when trying to insert the same identifier over and over again.
