 128 <br>&nbsp;<br><h3><a class=none name="usage">Usage</a></h3>
 129
 130 <p>Two functions and a macro are used to manage connections to the database:</p>
 131 <ul>
 132 <li>Function <a href="#connect">connect</a> connects to the database</li>
 133 <li>Function <a href="#disconnect">disconnect</a> disconnects from the database</li>
 134 <li>Macro <a href="#with-open-database">with-open-database</a> opens the database and ensures that it is properly closed after the code is run</li>
 135 </ul>
 136
 137 <p>To make queries to the database the following functions are provided:</p>
 138 <ul>
 139 <li><a href="#execute-non-query">execute-non-query</a> executes the query and returns nothing</li>
 140 <li><a href="#execute-single">execute-single</a> returns the first column of the first row of the result</li>
 141 <li><a href="#execute-one-row-m-v">execute-one-row-m-v</a> returns the first row of the result as multiple values</li>
 142 <li><a href="#execute-to-list">execute-to-list</a> returns all rows as the list of lists</li>
 143 </ul>
 144
 145 <p>Macro <a href="#with-transaction">with-transaction</a> is used to execute code within transaction.</p>
 146
 147 <p>Support for <a href="http://common-lisp.net/project/iterate/">ITERATE</a> is provided. Use the following clause:
 148   <blockquote><pre>(for (<i>vars</i>) in-sqlite-query <i>sql</i> on-database <i>db</i> &optional with-parameters (<i>&rest parameters</i>))</pre></blockquote>
 149 This clause will bind <i>vars</i> (a list of variables) to the values of the columns of query.</p>
 150
 151 <p>Additionally, it is possible to use the prepared statements API of sqlite. Create the prepared statement with <a href="#prepare-statement">prepare-statement</a>, bind its parameters with <a href="#bind-parameter">bind-parameter</a>, step through it with <a href="#step-statement">step-statement</a>, retrieve the results with <a href="#statement-column-value">statement-column-value</a>, and finally reset it to be used again with <a href="#reset-statement">reset-statement</a> or dispose of it with <a href="#finalize-statement">finalize-statement</a>.</p>
 152
 153 <p>Positional parameters in queries are supported (sqlite supports named parameters but this package does not support them). Parameters are denoted by question mark in SQL code.</p>
 154
 155 <p>Following types are supported:</p>
 156 <ul>
 157   <li>Integer. Integers are stored as 64-bit integers.</li>
 158   <li>Float. Stored as double. Single-float and double-float may be passed as a parameter, and double-float will be returned.</li>
 159   <li>String. Stored as an UTF-8 string.</li>
 160   <li>Vector of bytes. Stored as a blob.</li>
 161   <li>Null. Passed as NIL to and from database.</li>
 162 </ul>
