help you fix your problem I want to create a function that returns a random string of numbers and letters, In form (2 letters + 4 numbers + 2 letters) Example AD1256Cv , Use this-
private string RandomString()
        {
            var chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
            var numbers = "0123456789";
            var stringChars = new char[8];
            var random = new Random();

            for (int i = 0; i < 2; i++)
            {
                stringChars[i] = chars[random.Next(chars.Length)];
            }
            for (int i = 2; i < 6; i++)
            {
                stringChars[i] = numbers[random.Next(numbers.Length)];
            }
            for (int i = 6; i < 8; i++)
            {
                stringChars[i] = chars[random.Next(chars.Length)];
            }

            var finalString = new String(stringChars);
            return finalString;
        }

Mysql Sorting mixed strings of letters and numbers, letters before numbers


Tag : mysql , By : Alex Bartzas

around this issue Assuming all letters are upper case (as per your examples), use a case-sensitive (ie binary) order by after converting digits '0' through '9' to letters 'a' through 'j' respectively:
...
order by binary replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(
  name, '0', 'a'), '1', 'b'), '2', 'c'), '3', 'd'), '4', 'e'), '5', 'f'), '6', 'g'), '7', 'h'), '8', 'i'), '9', 'j')

Query is returning only numbers or numbers+letters combination from table. How to modify it to show records with letters


Tag : java , By : ap.
Date : March 29 2020, 07:55 AM
hope this fix your issue I want to receive records from column KEY_EXAMPLE only. When KEY_EXAMPLE column have records like "1234", or "1234a", code shows this kind of records, but when it have record like "abcd" it's not shown. ,
Why it's showing numbers or numbers+letters records only?
SELECT _id,Example FROM mytable WHERE Example; 
public Cursor showRecordsFromExample(){
    String[] selectedColumn = new String[]{_id, KEY_EXAMPLE};
    Cursor selectedCursor = sqLiteDatabase.query(MYDATABASE_TABLE, selectedColumn,
            null, null, null,
            null, null);
    return selectedCursor;
}
public Cursor showRecordsFromExample(){
    String[] selectedColumn = new String[]{_id, KEY_EXAMPLE};
    Cursor selectedCursor = sqLiteDatabase.query(MYDATABASE_TABLE, selectedColumn,
            KEY_EXAMPLE + " LIKE '%a%'", null, null,
            null, null);
}
