VARCHAR is of variable length but we need to specify the max length of the field (example : name VARCHAR(64)). If you want to modify the content of the string through the string pointer, you can try the following code: string* str_ptr = &str; str_ptr->at(0) = 'D'; When a variable of a class type is created, or instantiated, the variable that is created is known as an object. The corresponding type in the .NET Framework is the System.String class. The first 128 code points (0–127) of Unicode correspond to the letters and symbols on a standard U.S. keyboard.

Once you assign a string to a String variable, that string is immutable, which means you cannot change its length or contents. These options include finding string length, converting to upper or lower case, trimming text, or replacing text within the string. The XML processor does not replace line feeds, carriage returns, and tab characters in the content with space and keep them intact.

The syntax for specifying a RAW data item is: RAW (maximum_size) For example: RAW(256) The maximum_size, … Boolean type BooleanType: Represents boolean values. Returns a pointer to an array that contains a null-terminated sequence of characters (i.e., a C-string) representing the current value of the string object. MariaDB supports the following character sets and collations. It is represented by str class. There is no null-terminating character at the end of a C# string; therefore a C# string can contain any number of embedded null characters ('\0'). The string is different from the char type string in the C language. >>> type ('I am too.') Unicode uses the remaining code points (256-65535) for a wide variety of symbols. (1) Primitive Datatypes (ii)Reference Datatypes. In fact, VBScript has only one data type called Variant. A string can also be thought of as plain text. The timestamp value represents an absolute point in time. Sequences maintain a left-to-right order among the items and are stored and fetched by their relative positions.
