Sqlite Delete Query syntax in Android

I want to write a Query to delete a row from the table. I am confused of writing the statement. I need some help开发者_JS百科 in writing this. I am providing my requirement here with plain sql statement.

(Pseudo code)

delete from tablename where value =="string1" && value2 == "string2" && value3 == "string3";

I want to write this in the Sqlite syntax for android db.delete(tablename, whereclause, whereargs);.

I would be thankful for your help.

a better way would be to use

String where = "value1 = ?"
+ " AND value2 = ?"
+ " AND value3 = ?";
String[] whereArgs = {string1,string2,string3};

---

String table_name = "myTable";
String where = "value1 = 'string1'"
    + " AND value2 = 'string2'"
    + " AND value3 = 'string3'";
String whereArgs = null;
mDb.delete(table_name, where, whereArgs);

---

mdb.delete("tablename",new String("value1=? and Value2=? and value3=?"),new String[]{value1,value2,value3});

---

SQLiteDatabase db = this.getWritableDatabase();
db.execSQL("DELETE FROM tablename WHERE value1='"+string1+"' AND value2='"+string2+"' AND value3='"+string3+"' "); //delete  row in a table with the condition
db.close();
