Question

I wanna execute a Query for 10 times to get random values,
but my code never stops,

it keeps looping and gives no response.

This is my code

int j = 0;
do {
    DataSet AVATARLINE = new DataSet();
    SqlDataAdapter AVATARLINE_1 = new SqlDataAdapter("DECLARE
            @Random INT,@Upper INT,
            @Lower INT SET @Lower = (select MIN(ID)from MastryID)SET
            @Upper = (select MAX(ID)from MastryID)+1 SELECT
            @Random = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)SELECT @Random", connection);
    AVATARLINE_1.Fill(AVATARLINE);
    foreach (DataRow row in AVATARLINE.Tables[0].Rows)
    {
        for (int i = 0; i < AVATARLINE.Tables[0].Columns.Count; i++)
        richTextBox1.Text += row[i].ToString() + Environment.NewLine;
    }
}
while (j < 10); // 0-9

Any idea how to make it work for ONLY 10 times.

Here you go :)…
you dont seem incrementing j in your loop

int j = 0;
    do {
            DataSet AVATARLINE = new DataSet();
            SqlDataAdapter AVATARLINE_1 = new SqlDataAdapter("DECLARE @Random INT,@Upper INT,@Lower INT SET @Lower = (select MIN(ID)from MastryID)SET @Upper = (select MAX(ID)from MastryID)+1 SELECT @Random = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)SELECT @Random", connection);
            AVATARLINE_1.Fill(AVATARLINE);
            foreach (DataRow row in AVATARLINE.Tables[0].Rows)
            {
                for (int i = 0; i < AVATARLINE.Tables[0].Columns.Count; i++)
                    richTextBox1.Text += row[i].ToString() + Environment.NewLine;
            } 
        j++; 
        }
    while (j < 10); // 0-9
