character sets, the display length of a character string can differ from the number of CHARACTE RS in the string. When you specify a value for length that's shorter than the length of text-exp, then this function truncates the expression to the specified length. The bold part of the main idea is: The total length of the return value as they appear on your terminal screen the same length, note that is the length of the terminal display , not the actual length of the string in the data

is the number of strings returned, and if this number is shorter than the length of the original string, the Lpad function will intercept the string as a left-to-right n character;Pad_stringOptional parameter, this string is to be pasted to the right of the string, if this argument is not written, the Lpad function will paste a space on the right side of the string.Rpad (' Tech ', 7); will return ' tech 'Rpad (' Tech ', 2); will return ' Te '

Use of the padding function lpad/rpad in oracle, lpadrpadLpad 1. Syntax Lpad (string, pad_length, [pad_str])2. ExplanationThis function indicates filling the specified character to the specified length from the left side of the string. The space of the string is also included in the length.String: the length of the string to be filled. If the value is smaller than the length of the original string, the retu

The bold part indicates the total length of the returned values, just as they are displayed on your terminal screen.Terminal display LengthThe actual length (in bytes) not displayed in the database ). This is particularly evident in Multi-byte supported databases (such as simplified Chinese and AL32UTF8. The following example is used to understand this sentence: SQL LENGTHB (RPAD

the string is also counted into the length.String Pad_length: The length of the string to be populated, and if the value is smaller than the length of the original string, the string after that length that is intercepted from the left of the string is returned. PAD_STR: The string to be populated, an optional function, or, if there is no value, padding the right with a space.Example 1:select rpad (' abc ', ' 5 ', ' # ') from dual; -------------------

Lpad () function usage: The lpad function fills the string on the left with some specific characters. The syntax format is as follows: Lpad (string, n, [pad_string]) String: but a character or Parameter N: the length of the character, which is the number of returned strings. If the number is shorter than the length of the original string, the lpad function splits the string into n characters from left to right; Pad_string: it is an optional parameter. This string is to be pasted to the left of t

In mysql, The LPAD (s1, len, s2) function fills string s2 at the beginning of s1, so that the string length reaches len, and then returns string s1. Unlike LPAD, RPAD is filled at the end of the string. This article introduces how to use the padding function of mysqlLPAD and RPAD with insufficient digits. For more information, see.

What is "R "? R is a language and environment designed for Statistical Computing and graphic display. It is similar to the S system developed by Bell Laboratories John Chambers. It provides a series of statistical and graphical display tools (linear and nonlinear models, statistical tests, time series analysis, classification, clustering ,......). With regard to R, I am fortunate to have collected from the Internet the Chinese Document "introduction to R" Translated by Mr. Ding Guohui (g
