 +<h1>Inline Parameter Maps</h1>
 +
 +<p>If you prefer to use inline parameters instead of parameter maps, you can add
 +extra type information inline too. The inline parameter map syntax lets you
 +embed the property name, the property type, the column type, and a null value
 +replacement into a parametrized SQL statement. The next four examples shows
 +statements written with inline parameters.</p>
 +
 +<com:TTextHighlighter Language="xml" CssClass="source">
 +<statement id="insertProduct" parameterClass="Product">
 +  insert into PRODUCT (PRD_ID, PRD_DESCRIPTION)
 +  values (#id#, #description#)
 +</statement>
 +</com:TTextHighlighter>
 +
 +<p>The following example shows how <tt>dbTypes</tt> can be declared inline.</p>
 +
 +<com:TTextHighlighter Language="xml" CssClass="source">
 +<statement id="insertProduct" parameterClass="Product">
 +  insert into PRODUCT (PRD_ID, PRD_DESCRIPTION)
 +  values (#id, dbType=int#, #description, dbType=VarChar#)
 +</statement>
 +</com:TTextHighlighter>
 +
 +<p>The next example shows how <tt>dbTypes</tt> and null value replacements can also
 +be declared inline.</p>
 +
 +<com:TTextHighlighter Language="xml" CssClass="source">
 +<statement id="insertProduct" parameterClass="Product">
 +  insert into PRODUCT (PRD_ID, PRD_DESCRIPTION)
 +  values (#id, dbType=int, nullValue=-999999#, #description, dbType=VarChar#)
 +</statement>
 +</com:TTextHighlighter>
 +
 +<p>A more complete example.</p>
 +
 +<com:TTextHighlighter Language="xml" CssClass="source">
 +<update id="UpdateAccountViaInlineParameters" parameterClass="Account">
 + update Accounts set
 + Account_FirstName = #FirstName#,
 + Account_LastName = #LastName#,
 + Account_Email = #EmailAddress,type=string,dbType=Varchar,nullValue=no_email@provided.com#
 + where
 + Account_ID = #Id#
 +</update>
 +</com:TTextHighlighter>
 +
 +<div class="note"><b class="tip">Note:</b>
 +Inline parameter maps are handy for small jobs, but when there are a lot of
 +type descriptors and null value replacements in a complex statement, an
 +industrial-strength, external <tt>parameterMap</tt> can be easier.
 +</div>
 +
 +<h1>Standard Type Parameters</h1>
 +<p>In practice, you will find that many statements take a single parameter, often
 +an <tt>integer</tt> or a <tt>string</tt>. Rather than wrap a single value in another
 +object, you can use the standard library object (string, integer, et cetera)
 +as the parameter directly. The following example shows a statement using
 +a standard type parameter.</p>
 +
 +<com:TTextHighlighter Language="xml" CssClass="source">
 +<statement id="getProduct" parameterClass="System.Int32">
 +  select * from PRODUCT where PRD_ID = #value#
 +</statement>
 +</com:TTextHighlighter>
 +
 +<p>Assuming <tt>PRD_ID</tt> is a numeric type, when a call is made to this Mapped
 +Statement, a standard integer can be passed in. The <tt>#value#</tt> parameter
 +will be replaced with the value of the integer. The name <tt>value</tt> is simply
 +a placeholder, you can use another moniker of your choice. Result Maps support
 +primitive types as results as well.</p>
 +
 +<p>For your convenience, the following PHP primitive types are supported.</p>
 +<ul>
 +  <li><tt>string</tt></li>
 +  <li><tt>float</tt> or <tt>double</tt></li>
 +  <li><tt>integer</tt> or <tt>int</tt></li>
 +  <li><tt>bool</tt> or <tt>boolean</tt></li>
 +</ul>
 +
 +<h1>Array Type Parameters</h1>
 +<p>You can also pass in a array as a parameter object. This would usually be a an
 +associative array. The following example shows a <tt><statement></tt> using
 +an array for a <tt>parameterClass</tt>.</p>
 +
 +<com:TTextHighlighter Language="xml" CssClass="source">
 +<statement id="getProduct" parameterClass="array">
 +  select * from PRODUCT
 +  where PRD_CAT_ID = #catId#
 +  and PRD_CODE = #code#
 +</statement>
 +</com:TTextHighlighter>
 +
 +<p>In the above example, notice that the SQL in this Mapped Statement
 +looks like any other. There is no difference in how the inline parameters are
 +used. If an associative array is passed, it must contain keys named <tt>catId</tt>
 +and <tt>code</tt>. The values referenced by those keys must be of the appropriate
 +type for the column, just as they would be if passed from a properties object.</p>
