<concept id="GUID-F40E34F4-5B8B-523E-82B6-7717D8FD26AB" xml:lang="en"><title>Executing

SQL statements</title><shortdesc>The <codeph>RDbDatabase</codeph> class provides a member function, <codeph>Execute()</codeph>,

which directly executes <i>both</i> DDL and DML statements on the database.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>As most of these statements can take an extended time to complete, there

are also interfaces to execute these statements incrementally. </p>

<ul>

<li id="GUID-D73DC76D-6E12-542D-9E60-81A7CDDF221F"><p><codeph>RDbIncremental</codeph> provides

a member function, <codeph>Execute()</codeph>, which executes a DDL statement

incrementally.</p> </li>

<li id="GUID-AA5D4133-B777-5F3E-8DD1-3398D5012B11"><p><codeph>RDbUpdate</codeph> provides

the functionality for executing a DML statement incrementally.</p> </li>

</ul>

<p>DML statements need a different interface because it is not always possible

to know how many steps a DML operation is going to need.</p>
