The description of each procedure or function is broken down into the following parts. Note that items for which no "generates" entry is shown are available only as procedures.
cname in varchar2
The "c" in cname indicates a character data type (varchar2).
nsize in integer
The "n" in nsize indicates a number data type (integer).
dbuf in date
The "d" in dbuf indicates a date data type (date).
As in BNF notation, a vertical bar (|) in the syntax diagram means "or".
Note: Many HTML 3.0 tags have a large number of optional attributes that, if passed as individual parameters to the hypertext procedures or functions would make the calls quite cumbersome. In addition, some browsers support non-standard attributes. Therefore, each hypertext procedure or function that generates an HTML tag has as its last parameter cattributes, an optional parameter. This parameter enables you to pass the exact text of the desired HTML attributes to the PL/SQL procedure.
For example, the syntax for htp.em is:
htp.em (ctext, cattributes);
A call that uses HTML 3.0 attributes might look like the following:
htp.em('This is an example','ID="SGML_ID" LANG="en"');This line would generate the following:
<EM ID="SGML_ID" LANG="en">This is an example</EM>
`<` with '<`
Note: Although this section shows hypertext procedures (HTP), all of them are also available as hypertext functions (HTF).
Note: If cbackground and cattributes are NULL, this tag generates <BODY>.
This line produces:
<BODY background="/img/background.gif">
