Inserting values to SQLite table in Android

I am new in android app developement. I tried to insert values to SQLite database through the below code;

public class cashbook extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        SQLiteDatabase db;

        db = openOrCreateDatabase(
            "cashbookdata.db"
            , SQLiteDatabase.CREATE_IF_NECESSARY
            , null
            );

        final String Create_CashBook =
            "CREATE TABLE CashData ("
            + "id INTEGER PRIMARY KEY AUTOINCREMENT,"
            + "Description TEXT," 
            + "Amount REAL,"
            + "Trans INTEGER," 
            + "EntryDate TEXT);";

        db.execSQL(Create_CashBook);  
        final String Insert_Data="INSERT INTO CashData VALUES(2,'Electricity',500,1,'04/06/2011')";
        db.execSQL(Insert_Data);

It shows error on emulator开发者_如何转开发 - The application CashBook has stopped unexpectedly.

The database and table created , but the value insertion is not working. Please help me to resolve this issue. Thanks.

Seems odd to be inserting a value into an automatically incrementing field.

Also, have you tried the insert() method instead of execSQL?

ContentValues insertValues = new ContentValues();
insertValues.put("Description", "Electricity");
insertValues.put("Amount", 500);
insertValues.put("Trans", 1);
insertValues.put("EntryDate", "04/06/2011");
db.insert("CashData", null, insertValues);

okk this is fully working code edit it as per your requirement

public class TestProjectActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    SQLiteDatabase db;
    db = openOrCreateDatabase( "Temp.db"        , SQLiteDatabase.CREATE_IF_NECESSARY        , null          );
    try {
        final String CREATE_TABLE_CONTAIN = "CREATE TABLE IF NOT EXISTS tbl_Contain ("
                + "ID INTEGER primary key AUTOINCREMENT,"
                + "DESCRIPTION TEXT,"
                + "expirydate DATETIME,"
                + "AMOUNT TEXT,"
                + "TRNS TEXT," + "isdefault TEXT);";
        db.execSQL(CREATE_TABLE_CONTAIN);
        Toast.makeText(TestProjectActivity.this, "table created ", Toast.LENGTH_LONG).show();
        String sql =
            "INSERT or replace INTO tbl_Contain (DESCRIPTION, expirydate, AMOUNT, TRNS,isdefault) VALUES('this is','03/04/2005','5000','tran','y')" ;       
                db.execSQL(sql);
    }
    catch (Exception e) {
        Toast.makeText(TestProjectActivity.this, "ERROR "+e.toString(), Toast.LENGTH_LONG).show();  
}}}

Hope this is useful for you..
do not use TEXT for date field may be that was casing problem still getting problem let me know :)Pragna

You'll find debugging errors like this a lot easier if you catch any errors thrown from the execSQL call. eg:

 try 
 {
      db.execSQL(Create_CashBook);  
 }
 catch (Exception e) 
 {
       Log.e("ERROR", e.toString());
 }

I recommend to create a method just for inserting and than use ContentValues. For further info https://www.tutorialspoint.com/android/android_sqlite_database.htm

public boolean insertToTable(String DESCRIPTION, String AMOUNT, String TRNS){

    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues contentValues = new ContentValues();
    contentValues.put("this is",DESCRIPTION);
    contentValues.put("5000",AMOUNT);
    contentValues.put("TRAN",TRNS);
    db.insert("Your table name",null,contentValues);

    return true;
}

public class TestingData extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    SQLiteDatabase db;
    db = openOrCreateDatabase(
        "TestingData.db"
        , SQLiteDatabase.CREATE_IF_NECESSARY
        , null
        );
 }

}

then see this link link

okkk you have take id INTEGER PRIMARY KEY AUTOINCREMENT and still u r passing value... that is the problem :) for more detail see this still getting problem then post code and logcat

Since you are new to Android development you may not know about Content Providers, which are database abstractions. They may not be the right thing for your project, but you should check them out: http://developer.android.com/guide/topics/providers/content-providers.html

I see it is an old thread but I had the same error.

I found the explanation here: http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html

void execSQL(String sql)
Execute a single SQL statement that is NOT a SELECT or any other SQL statement that returns data.

void execSQL(String sql, Object[] bindArgs)
Execute a single SQL statement that is NOT a SELECT/INSERT/UPDATE/DELETE.
