Could be anything. Depend on the context. Vaguely one could say it is a defined unit separating data without (necessarily) being part of the data itself.

I.e. in the string "what is", the quotes delimit the string, but are not a part of it. A data stream can have a defined byte-sequence/flag/etc delimiting records; i.e a comma delimited list:

record1,record2 ,record3

And so on...

One can separate it into two major groups being; 1. string literals, and 2. data.

In the broad sense it can include x^n definitions. A space can be a separator for words. Newline for records in a list, - and so on.

Important to notice and not mix is the term operator, sorted by precedence and associativity:

Expand|Select|Wrap|Line Numbers

  
----------------------------------------------

Operators                        Associativity

----------------------------------------------

() [] -> .                       left to right 

! ~ ++ -- + - * (type) sizeof    right to left 

* / %                            left to right 

+ -                              left to right 

<<  >>                           left to right 

< <= > >=                        left to right 

== !=                            left to right 

&                                left to right 

^                                left to right 

|                                left to right 

&&                               left to right 

||                               left to right 

?:                               right to left 

= += -= *= /= %= 

&= ^= |= <<= >>=                 right to left 

,                                left to right 

----------------------------------------------

Also note that in C, semicolon is a statement terminator and not a separator. While i.e. pascal defines it as a statement separator.

mysql delimiter

by: j-marvin | last post by:

The example uses the mysql client delimiter command to change the statement delimiter from ; to // while the procedure is being defined. This allows the ; delimiter used in the procedure body to be passed through to the server rather than being interpreted by mysql itself. hi - i am using cli in interactive mode. i tried changing the delimiter to // but everytime i type a ; i get an error. what could i be doing wrong?

How to establish a delimiter pattern for input streams

I am trying to set up a delimiter character string for the input stream such that the delimiter string is "skipped over" in the input stream. Can someone suggest how to do this with some sample code?

Character delimiter ....

by: Raquel | last post by:

Could someone explain to me what the reason is for having a character delimiter (which is double quotes by default) for performing Loads/Imports on UDB? I would think that column delimiter along should have sufficed (of course it is the responsibility of the person performing the Load to ensure that the character he has chosen as column delimiter does not exist as a part of data). The problem I am facing is that I have a file generated...

I've been trying to coax this class to use something other than the default '$' but it seems setting it to something else has no discernible effect. Is it necessary to inherit from the class to do this? I've only been using Python for a couple of weeks so I'm not sure what the best approach is here. Thanks in advance.
