火神中间件的一些用法
<h3>打开数据集：</h3>
<pre><code class="language-delphi">FireQuery1.close;
FireQuery1.DataInfo.SQL.Text := 'Select * from bArea';
if FireQuery1.OpenData then
begin
end
else
ShowMessage(Firequery1.DataInfo.ErrMsg);</code></pre>
<h3>保存数据到服务器</h3>
<p>对于单表来说，使用下面的方法：
有两项必须设置：</p>
<pre><code class="language-delphi">DataInfo.TableName :='bArea'; //表名
DataInfo.PrimaryKey :='Id'; //主键</code></pre>
<h3>问题解答：</h3>
<h4>1.如何获取一个GUID：</h4>
<pre><code class="language-delphi">function TFireConnection.GetGUID:String;</code></pre>
<h4>2.如何获取服务器时间：</h4>
<pre><code class="language-delphi">function TFireConnection.GetServerTime:TDateTime;</code></pre>
<h4>3.如何获取整型ID（雪花id）：</h4>
<pre><code class="language-delphi">function TFireConnection.GetInt64:Int64;</code></pre>
<h4>其他的一些常用方法：</h4>
