Term: COMMENT

Definition:
In Oracle, comments may be placed in source code in two different ways:

Using a C-style slash-star to begin a comment and a star-slash to end the comment, like this:

/* this is a simple C-style comment block */



 /* this is another C-style comment 

block that spans

multiple lines. 

*/

Using a line that begins with a double-dash (-), like this:
```
-- a single line comment
```

A C-style comment (/*...*/) can span multiple lines if necessary, but cannot contain nested C-style comments. It can contain double-dash style comments.

The double-dash cannot span multiple lines.
