Collating Order for U.S. English Data
If you are using the default locale (U.S. English), the database server uses the code-set order of the default code set when it compares the character expressions that precede and follow the relational operator.
On UNIX™, the default
code set is the ISO8859-1 code set, which consists of the following
sets of characters:
- The ASCII characters have code points in the range of 0 to 127.
This range contains control characters, punctuation symbols, English-language characters, and numerals.
- The 8-bit characters have code points in the range 128 to 255.
This range includes many non-English-language characters (such as é ;, ö, and ñ) and symbols (such as £, ©, and ¿).
In Windows™, the default code set is Microsoft™ 1252. This code set includes both the ASCII code set and a set of 8-bit characters.
This table lists the ASCII code set. The Num columns
show ASCII code point numbers, and the Char columns display
corresponding ASCII characters. In the default locale, ASCII characters
are sorted according to their code-set order. Thus, lowercase letters
follow uppercase letters, and both follow digits. In this table, ASCII
32 is the blank character, and the caret symbol ( ^ ) stands for the
CTRL
key.
For example, ^X means CONTROL-X
