StringBuilder WordToReverse = new StringBuilder() StringBuilder ReversedString = new StringBuilder() Ĭhar ArrStr = StringToReverse.ToCharArray() You can use ToCharArray().Īnswer private static string ReverseEachWord(string StringToReverse) Question 8: Write a method to reverse each word of a string without using predefined functions. This can be done by both AJAX and postback. You can cache the element on the page, process data on the user control, and then write the response on the cached element.

But, for case 2 and case 3 union and union, all will behave differently. In case 1 both union and union will behave the same. Select name, id from Emp1 union all select name, id from Emp2 Select name, id from Emp1 union select name, id from Emp2 So union and union all will behave the same when each record is distinct in all the participating tables. Union all will give a record as many times as it occurs. Union will give a record only once even if it occurs several times. Question 2: When will union and union all behave the same?
