/**
 *<B>Title:</B> Execute Query with Map
 *<BR>
 *<B>Keywords:</B> query
 *<BR>
 *<B>Assertion ID:</B> A14.6.1-5.
 *<BR>
 *<B>Assertion Description: </B> The <code>Query.executeWithMap</code> method is
 *similar to the <code>execute</code> method, but takes its parameters from a
 *<code>Map</code> instance. The <code>Map</code> contains key/value pairs,
 *in which the key is the declared parameter name, and the value is the value
 *to use in the query for that parameter. Unlike <code>execute</code>, there is
 *no limit on the number of parameters.
