<p><strong>Special Parameters</strong>: the special parameter <additionalLimitations>, is provided to allow a program to filter more limited information based upon the user running the report. For example, if a user should only see a subset of the total report, and a second user see a different subset, this parameter will allow runtime modification of this. To use this parameter, you must do the two following things:</p>
|
- |
|
93 |
<ul>
|
- |
|
94 |
<li>In your query, surround all of your where clause (exclusive of the keyword <em>where</em>) in parentheses. At the outside of this block, place the special token <additionalLimitations></li>
|
- |
|
95 |
<li>In your call to Report->run, include the first parameter (empty, if need be), then pass the additional values to be use to limit in the second parameter.</li>
|

|

</ul>

The parameters column is actually a series of one or more lines, with each line corresponding to one parameter in the query column. Each line (parameter entry) consists of four values, delimited by the special string <em>++</em> (this may be redefined by QueryParameters->parametersDelimiter). The four values are defined in the following table
