I now sure what i'm doing wrong because java and SQLite for me new. So I need to make check when user is entering new data to DB if data with such "day" and "week_type" exists it need to be updated , else create new row.
public long creatEntry(int day2, int week_type2,
String desc2, String place2, String lessnum2) {
// TODO Auto-generated method stub
ContentValues cv = new ContentValues() ;
String update = "SELECT * FROM info WHERE day="+day2+" AND week_type="+week_type;
Cursor cr = ourDatabase.rawQuery(update, null);
if(cr!= null){
cv.put(day, day2);
cv.put(week_type, week_type2);
cv.put(desc, desc2);
cv.put(place, place2);
cv.put(lessnum, lessnum2);
return ourDatabase.update(DATABASE_TABLE,cv, day+ "=" +day2+ " AND "+week_type+ "=" +week_type2, null);
}
else{
cv.put(day, day2);
cv.put(week_type, week_type2);
cv.put(desc, desc2);
cv.put(place, place2);
cv.put(lessnum, lessnum2);
return ourDatabase.insert(DATABASE_TABLE, null, cv);
}
}
Use replace. It'll try to insert first, and if it happens to conflict due to a key constraint, it'll delete and insert those values. In your case, these two columns must be unique . Check it out:
