I have taken String value from a EditText and set it inside SELECT QUERY after WHERE condition

As

TextView tv = (TextView) findViewById(R.id.textView3);
EditTextet2 et = (EditText) findViewById(R.id.editText1);

String name = et.getText().toString();

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE name = '"+name+"'", null); 

c.moveToNext();

tv.setText(c.getString(c.getColumnIndex("email")));

But it doesn't work. Any suggestions?

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

How to use SELECT Query in Android sqlite?, Before getting into example, we should know what sqlite data base in android is.

SQLiteDatabase, Android SQLITE query selection example. In this example we are going to learn how to create a SQLite database adapter that will perform the basic operations  Android SQLITE query selection example In this example we are going to learn how to create a SQLite database adapter that will perform the basic operations such as creating the table, upgrading the database as well as providing access to the data based on given input parameters.

Try using the following statement:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE name = ?", new String[] {name});

Android requires that WHERE clauses compare to a ?, and you then specify an equal number of ? in the second parameter of the query (where you currently have null).

And as Nambari mentioned, you should use c.moveToFirst() rather than c.moveToNext()

Also, could there be quotations in name? That could screw things up as well.

166 Android SQLite SELECT query Part 3 |, SQLite is an open-source social database i.e. used to perform database operations on android gadgets, for example, putting away, controlling  Select the rows using List & lt; & Gt; On Android sqlite Hi I need help with getting list of rows using a list values. I was wondering if i could have a search query using list of strings. If so, how should that be implemented? For example. I have these values inside my List<Info> info. Jan 10, 2015

 public User searchUser(String name) {
    User u = new User();
    SQLiteDatabase db = this.getWritableDatabase(); //get the database that was created in this instance
    Cursor c = db.rawQuery("select * from " + TABLE_NAME_User+" where username =?", new String[]{name});
    if (c.moveToLast()) {
        u.setUsername(c.getString(1));
        u.setEmail(c.getString(1));
        u.setImgUrl(c.getString(2));
        u.setScoreEng(c.getString(3));
        u.setScoreFr(c.getString(4));
        u.setScoreSpan(c.getString(5));
        u.setScoreGer(c.getString(6));
        u.setLevelFr(c.getString(7));
        u.setLevelEng(c.getString(8));
        u.setLevelSpan(c.getString(9));
        u.setLevelGer(c.getString(10));
        return u;

    }else {
        Log.e("error not found", "user can't be found or database empty");
        return u;
    }

}

this is my code to select one user and one only so you initiate an empty object of your class then you call your writable Database use a cursor in case there many and you need one here you have a choice Use : 1-

   if (c.moveToLast()) { } //it return the last element in that cursor 

or Use : 2-

 if(c.moveToFirst()) {  } //return the first object in the cursor 

and don't forget in case the database is empty you'll have to deal with that in my case i just return an empty object

Good Luck

Comments
  • print name and make sure you are getting valid name. use c.moveToFirst(); instead of C....next() and try.
  • This example is very bad and allows for SQL Injections. Why not use the second parameter correctly instead of inserting null?
  • Solved my problem.
  • Please note that using c.getString(c.getColumnIndex("column1")) is better than c.getString(0): you won't have to update indexes if you change your query.
  • I would also escape name parameter to avoid SQL injection
  • This has an SQL Injection Problem
