@ </pre></blockquote>
@ <h3>Notes</h3>
@ <ul>
@ <li><p>The SQL must consist of a single SELECT statement</p></li>
@
@ <li><p>If a column of the result set is named "#" then that column
@ is assumed to hold a ticket number. A hyperlink will be created from
@ that column to a detailed view of the ticket.</p></li>
@
@ <li><p>If a column of the result set is named "bgcolor" then the content
@ of that column determines the background color of the row.</p></li>
@
@ <li><p>The <b>user()</b> SQL function returns a string
@ which is the login of the current user.</p></li>
@
@ <li><p>The first column whose name begins with underscore ("_") and all
@ subsequent columns are shown on their own rows in the table. This might
@ be useful for displaying the description of tickets.
@ </p></li>
@
@ <li><p>The <b>aux()</b> SQL function takes a parameter name as an argument
@ and returns the value that the user enters in the resulting HTML form. A
@ second optional parameter provides a default value for the field.</p></li>
@
@ <li><p>The <b>option()</b> SQL function takes a parameter name
@ and a quoted SELECT statement as parameters. The query results are
@ presented as an HTML dropdown menu and the function returns
@ the currently selected value. Results may be a single value column or
@ two <b>value,description</b> columns. The first row is the default.</p></li>
@
@ <li><p>The <b>cgi()</b> SQL function takes a parameter name as an argument
@ and returns the value of a corresponding CGI query value. If the CGI
@ parameter doesn't exist, an optional second argument will be returned
@ instead.</p></li>
@
@ <li><p>If a column is wrapped by the <b>wiki()</b> SQL function, it will
@ be rendered as wiki formatted content.</p></li>
@
@ <li><p>If a column is wrapped by the <b>tkt()</b> SQL function, it will
@ be shown as a ticket id with a link to the appropriate page</p></li>
@
@ <li><p>If a column is wrapped by the <b>chng()</b> SQL function, it will
@ be shown as a baseline id with a link to the appropriate page.</p></li>
@
@ <li><p>The <b>search()</b> SQL function takes a keyword pattern and
@ a search text. The function returns an integer score which is
@ higher depending on how well the search went.</p></li>
@
@ <li><p>The query can join other tables in the database besides TICKET.
@ </p></li>
@ </ul>
@
@ <h3>Examples</h3>
@ <p>In this example, the first column in the result set is named
@ "bgcolor". The value of this column is not displayed. Instead, it
@ selects the background color of each row based on the TICKET.STATUS
@ field of the database. The color key at the right shows the various
@ color codes.</p>

@ </blockquote>
#endif
@ <p>To see the TICKET.DESCRIPTION and TICKET.REMARKS fields, include

@ that begin with an underscore. Like this:</p>
@ <blockquote><pre>
@ SELECT
@ tn AS '#',
@ type AS 'Type',
@ status AS 'Status',
@ sdate(origtime) AS 'Created',

@ priority AS 'Pri',
@ title AS 'Title',
@ description AS '_Description', -- When the column name begins with '_'
@ remarks AS '_Remarks' -- the data is shown on a separate row.
@ FROM ticket
@ </pre></blockquote>

@ <p>Or, to see part of the description on the same row, use the
@ <b>wiki()</b> function with some string manipulation. Using the
@ <b>tkt()</b> function on the ticket number will also generate a linked
@ field, but without the extra <i>edit</i> column:
@ </p>
@ <blockquote><pre>
@ SELECT
@ tkt(tn) AS '',
@ title AS 'Title',
@ wiki(substr(description,0,80)) AS 'Description'
@ FROM ticket
