<p><b><font face="Arial">virtual void Execute();<br>
throw (SAException);</font></b></p>
<p> Executes the
current command.
</p>
<h3>Remarks</h3>
<p> Use the <strong>Execute</strong> method to execute the query
or stored procedure specified in the command text.
<strong>Execute</strong>
method calls <A href="Command_Prepare.html">Prepare</A> method implicitly if needed. If the
command has input parameters, they should be bound before calling
<strong>Execute</strong>
method. Input parameters represented by <strong>SAParam</strong> object. To bind input
variables assign a value to <b>SAParam</b>
object returning by <A href="Command_Param.html">Param</A>
or
<A href="Command_ParamByIndex.html">ParamByIndex</A>
methods or bind input
variables using stream <A href="Command_operator_bind.html">operator <<</A>.<br>
</p>
<p>A command (an SQL statement or procedure)
can have a result set after executing. To check whether a result set
exists use <A href="Command_isResultSet.html">isResultSet</A> method. If result set
exists, a set of <b>SAField</b>
objects is created after command execution. Rows from the result
set can be fetched one by one using <A href="Command_FetchNext.html">FetchNext</A>
method. To get field
description or value use <A href="Command_Field.html">Field</A>
method.
</p>
<p>
Output parameters represented by <strong>SAParam</strong> objects. They are available
after command
execution. To get parameter description or value use
<A href="Command_Param.html">
Param
</A>
or <A href="Command_ParamByIndex.html">ParamByIndex</A>
methods.
