Question

I have a text view in which user enters a string. I need to search for that string in a table and return a boolean value if a string matches.

I am not into SQL, so can anyone please help me figure out how to do it.

Answer 1

Assuming that you know the basics & the object db of type SQLiteDatabase exists in your DataAccessLayer, below is the function which returns true false based on whether the location exists or not?

public boolean IsRecordExists(long empid) throws SQLException
{
     String where = "empid =" + empid;
     Cursor mCursor = db.query(true, "employeeinfo", new String[] {"empid"}, where, null,null, null, null, null);

      if (mCursor != null) 
      {
           if(mCursor.moveToFirst())
                return true;
          else
                return false;
       }
    return false;
}
